Steel connections are used to join steel members like beams and columns. There are different types of connections classified by connecting medium like bolted, welded, and riveted. Bolted connections are common and cost-effective. Welded connections provide rigidity but require careful welding and inspection. Common connections include single and double plate angle connections for beams to columns, and seated and top-and-bottom angle connections for moments. Proper connections allow complex steel structures to be designed and fabricated.

Methods for designing tension members, including consideration of cross-sectional area and end connections, are outlined.
The document discusses bolted connections, describing different types of bolts according to material, strength, shear type, fit, pitch, and head shape. It outlines advantages like strength, speed of installation, and easy removal compared to rivets. Disadvantages include reduced strength in axial tension and from loosening under vibration. Types of bolted joints include lap, butt, shop, and field joints. Analysis and design of bolted connections is similar to rivets, accounting for bolt strength based on nominal diameter. Design of bolted shear connections uses laws of friction to calculate load capacity based on number of interfaces and clamping force. An example problem is given to design a doubly bolted lap joint.
Connections are devices used to join structural elements together to safely transfer forces between them. There are different types of connections classified by their means of connection, such as welded, riveted, and bolted, and by the forces transferred, such as truss connections, fully restrained connections, and partially restrained connections. Fully restrained connections provide continuity between structural members and allow over 90% of moment to be transferred to provide greater flexural resistance. Partially restrained connections have less rigidity than fully restrained connections and allow some percentage of moment and full shear to be transferred. Semi-rigid connections provide rigidity between fully restrained and simple connections and transfer approximately 20-90% of moment.
Connections are critical structural elements that join members in steel structures. Common connection types include bolted, welded, and bolted-welded combinations. Connections are classified based on the connecting medium, type of forces transmitted, and elements joined. Riveted connections were previously common but have been replaced by bolted connections which are faster and cheaper to install. Welded connections provide rigidity but require careful design to avoid cracking. Modern connections often combine bolting and welding for strength and economy. Shear and moment connections behave differently in transmitting forces between members like beams and columns. Proper connection design is important for structural integrity and safety.
This presentation summarizes different types of bolted connections. It discusses bearing bolts, which can be unfinished or finished.

Connections are structural elements used to join members in a steel framework. Common types include bolted connections, welded connections, and bolted-welded combinations. Bolted connections use bolts loaded in tension, shear, or a combination, while welded connections fasten members primarily through welding. Various connection configurations are used for beams to beams, beams to columns, column splices, and attaching columns to foundation plates with anchor bolts. Proper connection design considers the forces and structural role of the connecting members.
This document discusses types of bolt connections based on arrangement of bolts and plates, mode of load transmission, and nature and location of load. There are two main types of joints subjected to axial loads: lap joints and butt joints. Butt joints are preferable to lap joints because the load is split between members, eliminating eccentricity and bending. Bolt connections can fail due to shear, bearing, or tension failures of bolts or plates. The design strength of bolts is governed by their strength in shear, bearing, or tension with safety factors applied.

Steel Structures - Building technology.pptxNikhil Raut
Steel structures are commonly used for high-rise buildings, long-span structures, industrial and warehouse buildings, and temporary structures due to steel's strength, light weight, speed of construction, and ability to create large spaces. Steel structures have advantages such as strength, flexibility, ductility, stability, earthquake resistance, and lighter weight compared to other materials. However, steel loses strength at high temperatures and is susceptible to corrosion. Common steel sections include angles, channels, I-beams, T-beams, round/square bars, and plates. Steel connections are made through bolting, riveting, and welding. Portal frames provide wide spans and are lightweight but require large members and cranes for erection.
Coupling is one kind of mechanical device which is used to connect two shafts together at their
ends for the purpose of transmitting power.
The primary purpose of couplings is to join two pieces of rotating equipment while permitting
some degree of misalignment or end movement or both.
A rigid coupling is a unit of hardware used to join two shafts within a motor or mechanical system.
It may be used to connect two separate systems, such as a motor and a generator, or to repair a
connection within a single system. A rigid coupling may also be added between shafts to reduce
shock and wear at the point where the shafts meet.
Flanged coupling is a type of rigid coupling in which two co-linear shafts are connected by the
flanges. The coupling enables torque transmission between the shafts & prevents relative rotation
between them.
In the project work a flanged coupling was made by local material available & the analysis of
various stresses & safety factor was also performed.
The outcome of analysis is there’s no danger of failure by pure shear, even if a fatigue strength
reduction factor is included, but this same section may have severe & undefinable bending stresses
on it if the flanges are imperfectly aligned, and they surely will be. The bolts bending was neglected
since they were too small compared to the result outcome.
Finally, the computed factor of safety of the flanges suggest that it would withstand repeated
bending if the misalignment is small.
This document discusses specifications for structural steel design published by organizations like AISC and AASHTO. It covers the two main design methodologies: Allowable Strength Design (ASD) and Load and Resistance Factor Design (LRFD). ASD divides the nominal strength by a safety factor while LRFD uses load and resistance factors. The document also classifies steel sections as compact, non-compact, or slender based on width-to-thickness ratios. It describes hot rolled, cold rolled, and built-up steel sections as well as their uses and properties. Built-up members are constructed by connecting plates or shapes and may be needed for large areas, rigidity, or connection requirements.

The document discusses ductility and ductile detailing in reinforced concrete structures. It states that structures should be designed to have lateral strength, deformability, and ductility to resist earthquakes with limited damage and no collapse. Ductility allows structures to develop their full strength through internal force redistribution. Detailing of reinforcement is important to avoid brittle failure and induce ductile behavior by allowing steel to yield in a controlled manner. Shear walls are also discussed as vertical reinforced concrete elements that help structures resist earthquake loads in a ductile manner.
The document discusses steel structures and structural drafting. It covers various topics related to steel including properties, structural joints, technical terms, and design elements.

The document provides information needed for structural drafting and elementary structural design.
Resistance welding is a welding process that uses heat generated by resistance to electric current passing through the workpieces. There are several types of resistance welding including spot welding, seam welding, projection welding, flash welding, upset welding, percussion welding, and high frequency resistance welding. Spot welding is commonly used in automotive manufacturing to join vehicle body parts and involves applying pressure and electric current between two electrodes to weld metal sheets together.
This document summarizes steel roof trusses. Most building roofs can be framed with prefabricated light-gauge steel trusses, which offer a high-strength, lightweight roof system that can be installed quickly. Steel trusses are manufactured from C-shaped galvanized steel and are stronger than wood trusses. They are constructed by connecting chord and web members made of steel into triangular shapes, then bolting or welding them together on the ground before installing the completed truss on the roof. All steel roofing has a protective metallic coating to prevent rusting.

A high-Speed Communication System is based on the Design of a Bi-NoC Router, ...DharmaBanothu
The Network on Chip (NoC) has emerged as an effective
solution for intercommunication infrastructure within System on
Chip (SoC) designs, overcoming the limitations of traditional
methods that face significant bottlenecks. However, the complexity
of NoC design presents numerous challenges related to
performance metrics such as scalability, latency, power
consumption, and signal integrity. This project addresses the
issues within the router's memory unit and proposes an enhanced
memory structure. To achieve efficient data transfer, FIFO buffers
are implemented in distributed RAM and virtual channels for
FPGA-based NoC. The project introduces advanced FIFO-based
memory units within the NoC router, assessing their performance
in a Bi-directional NoC (Bi-NoC) configuration. The primary
objective is to reduce the router's workload while enhancing the
FIFO internal structure. To further improve data transfer speed,
a Bi-NoC with a self-configurable intercommunication channel is
suggested. Simulation and synthesis results demonstrate
guaranteed throughput, predictable latency, and equitable
network access, showing significant improvement over previous
designs

Covid Management System Project Report.pdfKamal Acharya
CoVID-19 sprang up in Wuhan China in November 2019 and was declared a pandemic by the in January 2020 World Health Organization (WHO). Like the Spanish flu of 1918 that claimed millions of lives, the COVID-19 has caused the demise of thousands with China, Italy, Spain, USA and India having the highest statistics on infection and mortality rates. Regardless of existing sophisticated technologies and medical science, the spread has continued to surge high. With this COVID-19 Management System, organizations can respond virtually to the COVID-19 pandemic and protect, educate and care for citizens in the community in a quick and effective manner. This comprehensive solution not only helps in containing the virus but also proactively empowers both citizens and care providers to minimize the spread of the virus through targeted strategies and education.
3. • Introduction to topic
• Components of connections
• Classification
• Advantages Disadvantages
• conclusions
4. Connections are structural elements used for joining different
members in steel framed structures.
Steel structure is assemblage of different members such as “beams,
columns” which are connected to each other usually at member ends
that shows one composite unit.
6. On the Basis of Connecting Medium.
According to the type of internal
forces.
According to the type of structural
Elements.
According to the type of members
joining
8. Used for very long time.
Made up of:
Round Ductile steel bar called shank.
A head at one end
The length of the rivet should sufficient to
form the second head.
Design - very similar to bearing type of
bolted connection.
9. Heating of the rivet
Inserting it to an oversize hole pressure to the
head.
Squeezing the plain End by Pneumatic driver
Round
head.
On Cooling Reduces in
Length–Clamping Force
10.
11. The introduction of high strength structural bolts.
The labour costs associated with large riveting
crews
The cost involved in careful inspection and
removal of poorly installed rivets.
The high level of noise associated with driving
rivets.
Riveting was a very dangerous and time
consuming process
12. Bolting is a very common method of fastening
steel members.
Bolting is particularly cost effective in the field.
Fastened Together primarily by Bolts.
Bolts may be loaded in:
• Tension
• Shear
• Both Tension & Shear
13. Advantages
1. The bolting operation is very silent
2. Bolting is a cold process hence there is no risk of
fire
3. Bolting operation is more quicker than riveting.
4. Less man power is required in making the
connections.
Disadvantages
1. If subjected to vibratory loads, results in reduction
in
strength get loosened.
2. Unfinished bolts have lesser strength because of
non uniform diameter
15. Groove weld(more reliable than others).
Fillet weld(mostly use weaker than groove and
others).
Plug(expensive-poor transmission of tensile
forces).
Slot (expensive-poor transmission of tensile
forces)
16.
17. Advantages
Economical – Cost of materials and labors.
Efficiency is 100% as compared to rivets (75- 90%)
Fabrication of Complex Structures – Easy – like
Circular Steel pipes.
Provides Rigid Joints – Modern Practice is of Rigid
Joints.
Disadvantages
× No provision for expansion or contraction
therefore
× greater chances of cracking.
× Uneven heating and cooling - member may distort
–may result in additional stresses.
× Inspection is difficult and more costlier than rivet
18. Most connections are Shop Welded and Field
Bolted types.
More Cost Effective
Better Strength &
Ductility characteristics –Fully welded
19. Shear (semi rigid, simple) connections
Allows the beam end to rotate without a
significant restraint.
Transfers shear out of beam
Moment (rigid) connections
Designed to resist both Moment and Shear.
Often referred - rigid or fully restrained connections
Provide full continuity between the connected members
Designed to carry the full factored moments.
Principal Reason - buildings has to
resist theeffect of lateral forces.
20. Single plate angle Connections
A plate is welded to secondary
section (beam)
An Angle is welded to Primary
Section (column or Beam)
Double web angle connections
Two angles welded
After erection the angles are bolted or
site welded to the primary member.
Two angles welded
21. Top and seated angle connections
Generally used in case of moment connections.
Two angles are provided at top and bottom
of the beam to resist moment.
Generally used for lesser moments where
heavy loads are not acting
22. Seated beam connection
Generally used in case of shear connections.
A seating angle - at bottom of secondary
beam - shop welded to the primary member.
Seating angle resists vertical shear coming
from the beam.
23. Beam to beam connections
Column to column connections (column splices)
25. From above discussion we conclude that with the help
of connection we come up with:
Complex design and digital modelling.
ease of fabrication and erection
The desirable structure (any shape we can design).
Connection are Designed for Seismic Ductility
Demands
Connections are Designed for Fire Ductility
Demands etc.
