Plastic analysis

Adnan. Ali

This presentation introduces plastic analysis concepts. It discusses stress-strain curves and the difference between elastic and plastic analysis. Key assumptions of plastic analysis are that plane sections remain plane and the stress-strain relationship is identical in compression and tension. Plastic hinges form where the moment equals the plastic moment. Shape factors determine the plastic modulus for different cross-sections. Methods of plastic analysis include static and kinematic approaches. Failure mechanisms involve forming plastic hinges until collapse. Beam examples and problems are provided to demonstrate plastic analysis methods.

WSM and LSM steel structures

Civil Insider

Get PPT here What is the WSM method? In the working stress method, the stress-strain curve is assumed to be linear to the yield stress. To overcome the problems and damages due to uncertainty in design, permissible stress is kept as a fraction of the yield stress. As factor of safety is the ratio of yield stress to working stress, the members of the structure are sized to keep stresses within the permissible value. The working stress method is the oldest systematic analytical design method. Although IS 800-2007 gives more details and preferences to limit state method, it also permits the use of the working stress method wherever the limit state method is not practically adaptable. In Limit State Method, structure should be able to carry and withstand all the loads which will act on it throughout its life. Structure should not suffer total collapse under any kind of accidental loads such as explosions.

Structural analysis 2

R VIJAYAKUMAR

This document discusses various concepts related to structural analysis of arches: 1. An arch is a curved girder supported at its ends, allowing only vertical and horizontal displacements for arch action. 2. The general cable theorem relates the horizontal tension and vertical distance from any cable point to the cable chord moment. 3. Arches are classified based on support conditions (3, 2, or 1 hinged) or shape (curved, parabolic, elliptical, polygonal). 4. Horizontal thrust in arches reduces the bending moment and is calculated differently for various arch types (e.g. parabolic) and loading (e.g. UDL).

Soil stabilisation (1)

Safiullah Khan

This document discusses different methods for soil stabilization, including mechanical, physical, chemical, and bituminous stabilization. Mechanical stabilization involves compacting soil to increase density and strength. Physical stabilization involves blending soils or adding admixtures to improve properties. Chemical stabilization uses lime, cement, or other chemicals like calcium chloride to react with soils and modify their characteristics. Bituminous stabilization involves adding bitumen or asphalt to seal soil pores and increase cohesion between particles. The document provides details on appropriate soil types, required quantities, and construction methods for each stabilization technique.

Design & Analysis of G+2 Residential Building Using STAAD Pro

PARAS TANEJA

Concrete is a widely used construction material consisting of cement, water, and aggregates. The strength of concrete is specified using its 28-day cube strength in N/sq.mm. Formwork is used to mold wet concrete into desired shapes and allow it to cure. Formwork design involves choosing traditional or systematic approaches using wood or steel components like props, beams, sheathing to form columns, walls, and beams until the concrete gains sufficient strength. Proper formwork is important for quality concrete finish and structural integrity.

It also describes the development of modern codes of practice, which have expanded the use of loadbearing masonry beyond empirical rules to the rational design of multi-storey buildings. The document outlines basic design considerations for loadbearing masonry, such as compatible building typologies, and provides a high-level classification of masonry wall systems.

Bituminous penetration macadam base course

Aglaia Connect

This document discusses the process of constructing a bituminous penetration macadam base course. Aggregate is first spread and compacted dry, then hot bitumen binder is sprayed over it. Alternatively, a bituminous macadam mix can be prepared in a hot mix plant and transported to the construction site, where it is laid down in layers using a paver and compacted to the specified thickness and level. The base course provides a flexible pavement base for short roads or small projects where a hot mix plant is not available.

Diaphragm wall: Construction and Design

Umer Farooq

The document discusses diaphragm walls, which are concrete or reinforced concrete walls constructed below ground using a slurry-supported trench method. Diaphragm walls can reach depths of 150 meters and widths of 0.5-1.5 meters. They are constructed using tremie installation or pre-cast concrete panels. Diaphragm walls are suitable for urban construction due to their quiet installation and lack of vibration. The document discusses different types of diaphragm walls based on materials and functions, and provides details on their design, construction process, and material requirements.

Coffer dam and its type

Gaurang Kakadiya

Coffer dams are temporary structures built to retain water and soil in order to create a dry work area for construction projects. There are several types of coffer dams suited to different conditions, including earth-filled, sheet pile, and cellular designs. Key considerations in selecting a coffer dam include water depth, area size, soil/river bed conditions, and potential for erosion or flooding. Proper design is needed to withstand hydrostatic pressures and ensure structural integrity until the permanent structure is complete.

Design of slender columns as per IS 456-2000

PraveenKumar Shanmugam

The document discusses the design of slender columns. It defines a slender column as having a slenderness ratio (length to least lateral dimension) greater than 12. Slender columns experience appreciable lateral deflection even under axial loads alone. The design of slender columns can be done using three methods - the strength reduction coefficient method, additional moment method, or moment magnification method. The document outlines the step-by-step procedure for designing a slender column using the additional moment method, which involves determining the effective length, initial moments, additional moments, total moments accounting for a reduction coefficient, and redesigning the column for combined axial load and bending.

Slope stability

Dr. Pallavi Badry

This document provides an overview of slope stability and analysis. It defines different types of slopes as natural, man-made, infinite and finite. Common causes of slope failure like erosion, seepage, drawdown, rainfall, earthquakes and external loading are described. Key terms used in slope stability are defined, including slip zone, slip plane, sliding mass and slope angle. Types of slope failures are identified as face/slope failure, toe failure and base failure. Methods for analyzing finite slope stability, like Swedish circle method, Bishop's simplified method and Taylor's stability number are introduced. Infinite slope analysis is described for cohesionless, cohesive and cohesive-frictional soils. Example tutorial problems on slope stability calculations are

Prestressed Concrete

Ravi Savani

Prestressed concrete is concrete that is placed under compression using tensioned steel strands, cables, or bars. This is done through either pre-tensioning or post-tensioning. In pre-tensioning, the steel components are tensioned before the concrete is poured, while in post-tensioning, the steel components are tensioned after the concrete has hardened. Prestressed concrete provides benefits over reinforced concrete like lower construction costs, thinner structural elements, and longer spans between supports.

DESTRUCTIVE AND NON-DESTRUCTIVE TEST OF CONCRETE

Karan Patel

The standard method of evaluating the quality of concrete in buildings or structures is to test specimens cast simultaneously for compressive, flexural and tensile strengths. The main disadvantages are that results are not obtained immediately; that concrete in specimens may differ from that in the actual structure as a result of different curing and compaction conditions; and that strength properties of a concrete specimen depend on its size and shape. Although there can be no direct measurement of the strength properties of structural concrete for the simple reason that strength determination involves destructive stresses, several non- destructive methods of assessment have been developed.
