Slab is a flat piece of concrete used as a walking surface or load bearing element. It can be supported by walls, beams, or columns. Slabs provide a flat surface and act as insulators while supporting loads. Slabs are classified as one-way, two-way, flat plate, or waffle depending on their reinforcement configuration and load distribution. One-way slabs are reinforced in one direction while two-way slabs carry load in two directions. Flat plate slabs do not use beams but instead rely on slab reinforcement to carry loads. Waffle slabs contain ribs to increase stiffness. Common slab issues include cracking from inadequate design or construction, and dampness from moisture penetration.
Slab is a thin concrete structure used for flooring that can be square, rectangular, or circular. Slabs vary in thickness from 4-6 inches depending on load and are made of cement, coarse aggregate, fine aggregate, and reinforcement bars. There are several types of slabs including one-way slabs which carry load in one direction, two-way slabs which carry load in two directions, joist slabs which have concrete ribs for support, and precast slabs which are constructed off-site and transported. Other slab types include flat plates, flat slabs, waffle slabs, hollow core slabs, and composite slabs which incorporate a steel deck.
The document discusses different types of slabs used in construction. It defines a slab as a thin concrete structure used for flooring that can be square, rectangular or circular in shape. The main types discussed are:
1. Flat slab - A beamless slab constructed directly on columns for a simpler design.
2. Conventional slab - Supported by beams on columns, which can be one-way or two-way depending on load direction.
3. Sunken slab - Used below washrooms to hide pipes below the floor level.
4. Hallow core slab - A precast slab with voids that requires less concrete and provides service ducts.
Coffered ceilings and slabs are rigid, planar structures that use a series of intersecting ribs to distribute loads across a space. The document discusses the history and architectural uses of coffered ceilings. It also describes different types of coffered slab structures like waffle slabs and drop slabs that are used for their load bearing capacities in long span structures like schools and hospitals. Various coffered slab construction techniques are outlined, including the use of precast elements and how services can be run through the coffered spaces.
The entire process of structural planning and design requires not only imagination and conceptual thinking but also sound knowledge of practical aspects, such as recent design codes and bye-laws, backed up by ample experience, institution and judgment.
It is emphasized that any structure to be constructed must satisfy the need efficiency for which it is intended and shall be durable for its desired life span. Thus, the design of any structure is categorizes into following two main types:-
1. Functional design
2. Structural design
Once the form of the structure is selected, the structural design process starts. Structural design is an art and science of understanding the behavior of structural members subjected to loads and designing them with economy and elegance to give a safe, serviceable and durable structure.
This document discusses different types of reinforced concrete slabs, including one-way slabs, two-way slabs, flat slabs, and ribbed slabs. One-way slabs are supported on two sides and bend in one direction, while two-way slabs are supported on all four sides and bend in both directions. Flat slabs do not have beams and loads are transferred directly to columns, providing a plain ceiling. Ribbed slabs contain reinforced concrete ribs spaced no more than 1 meter apart between which the slab spans.
Flat slabs are reinforced concrete slabs that are supported directly by columns without beams. They provide minimum depth, fast construction, and flexible column placement. There are four main types: slabs without drops and with column heads, slabs with drops and without column heads, slabs with both drops and column heads, and typical flat slabs. Column heads increase shear strength while drops increase shear strength and negative moment capacity. Flat slab systems can be either one-way or two-way depending on span ratios and load distribution. Advantages include simple formwork, no beams, and minimum depth, while disadvantages include potential interference from drops.

This document provides information about space frames, cable structures, and folded plate structures. It defines a space frame as a truss-like, lightweight rigid structure constructed from interlocking struts in a geometric pattern. Space frames can span large areas with few interior supports. Folded plates are assemblies of flat plates rigidly connected along their edges to form a structural system without additional beams. Cable structures derive their strength from tension forces in the cables rather than from bending or compression. Common cable structures include suspension bridges, cable-stayed bridges, and cable-supported roofs.

This document provides information on various types of foundations used in construction, including isolated footings, grillage foundations, raft foundations, and rebar (reinforcing steel). Isolated footings are independent footings used to support single columns. Grillage foundations consist of steel beams in tiers to distribute loads over a large area for heavy structures. Raft foundations are concrete slabs that extend across a building footprint to spread loads. Rebar is steel reinforcement embedded in concrete to increase its tensile strength. The document discusses construction details and reinforcement for these foundation types.
Waffle slabs are reinforced concrete slabs reinforced in two orthogonal directions, forming a ribbed plate. They are characterized by their total edge height, lightening block height, rib spacing, rib thickness, and compression layer thickness. Waffle slabs can adequately support distributed and point loads in two directions. Benefits include flexibility, light weight allowing longer spans, fast construction, slim depths, robustness, vibration control, thermal mass, and durability. Waffle slabs are constructed with ribs forming a grid pattern and solid fills at supports. Larger spans may use post-tensioning or joist construction. Proper design considers loads, materials, deformations, and tile installation compatibility.
This document discusses different types of slabs used in construction. It defines slabs as structural members that provide flat horizontal surfaces.

This document summarizes the post-slab structural system. In a post-slab system, a reinforced concrete slab is supported directly by concrete columns without beams. C.A.P Turner invented the first post-slab structure in 1906. Le Corbusier popularized the system after World War I. Load is transferred from the slab to posts and then to the ground. Slab thickness and column size are based on span length. Post-slab allows for variable floor plans and large openings. Advantages include reduced height and flexibility, while limitations include large dead loads and lack of stability against lateral forces.
The document discusses flat grid or waffle slab systems. It defines waffle slabs as having two-directional reinforcement on the outside, giving it a waffle-like shape. This provides stability without using much material, making it suitable for large flat areas like foundations and floors. Waffle slabs are used in industrial and commercial buildings where large spans are needed with few columns. They provide features like using less concrete and steel than traditional slabs while providing strength and resistance to cracking and sagging. The document outlines the production, design, and construction process for waffle slabs and notes some iconic landmarks that have utilized this system.
The document discusses reinforced concrete floor and roof systems. It describes one-way systems that have reinforcement running in one direction and two-way systems that have reinforcement running in two perpendicular directions. One-way systems include slabs supported by beams or joists and are suitable for shorter spans and lighter loads. Two-way systems include flat plates and slabs supported on all sides that can support intermediate to heavy loads over longer spans.
Slabs are structural members that support transverse loads and transfer them to supports via bending. They are commonly used as floors and roofs. One-way slabs bend in only one direction across the shorter span like a wide beam, while two-way slabs bend in both directions if the ratio of longer to shorter span is less than or equal to 2. Design of one-way slabs involves calculating bending moment and shear force, selecting reinforcement ratio and bar size, and checking deflection, shear, and development length.
The document discusses foundations and roof structures. It describes foundations as having substructures below ground level that transmit loads to the soil, and superstructures above ground. It outlines different types of shallow foundations like isolated footings, strip footings, combined footings, and raft foundations. Deep foundations include pile foundations. The document also defines key terms for roofs like pitch, eaves, ridges, and discusses roof structural elements like purlins, battens, and trusses. Roof design considerations include strength, weather resistance, insulation, and drainage.
Building materials and construction Technology Roofs.pptxAdarshChatra
A roof provides structural covering to protect a building from weather. The main functions of a roof are to provide protection from weather, enclose space, and protect interior from moisture and heat loss. Roofs can be flat, pitched, or curved. Common roof types include simple slab, lean-to, couple close, collar beam, double purlin, and framed trussed roofs using king post or queen post designs. Roof design considers span, materials, loads, wind pressure, and weather resistance.
The document provides information on different types of foundations used in construction.

Reinforced concrete is well-suited for constructing stairs due to its fire resistance, durability, strength, and pleasing appearance. R.C.C. stairs can be designed in various forms including straight flights, inclined slabs with half landings, string beams, cranked slabs, cantilevers, and spirals. The type of stair adopted depends on the space and loading conditions. Common stair arrangements include single straight flights, inclined slabs spanning longitudinally, string beams with horizontal slab spanning, cranked slabs inducing bending and torsion stresses, cantilever stairs with central supporting walls, and spiral or helical stairs used in prestige buildings.
Foundations transmit loads from structures to the ground. Shallow foundations have depths less than their widths and include footings and rafts. Deep foundations have greater depths and include piles and caissons/wells. Footing types include isolated, wall, combined, cantilever, inverted arch, and raft. Piles can be end-bearing, friction, or composite. Requirements for good foundations include distributing loads over large soil areas without exceeding bearing capacity and minimizing settlement. Methods to improve soil bearing capacity include increasing depth, draining water, compacting, grouting, and chemical treatment.
A grid slab or waffle slab is a reinforced concrete floor system with a waffle-like pattern of ribs. The ribs form a grid that runs in two directions, giving the underside a waffle-like appearance. This allows the slab thickness to be minimized while maintaining strength. Waffle slabs provide good load distribution, vibration control, and structural stability, making them suitable for use in airports, hospitals, and other large structures.
This document discusses lime, which is a general term for calcium-containing inorganic materials like calcium carbonates, oxides, and hydroxides. Limestone or chalk rocks are primarily made of calcium carbonate and can be processed through calcination to produce quicklime, which is calcium oxide. Quicklime is then mixed with water in a process called slaking to produce slaked lime or hydrated lime, which is calcium hydroxide. Slaked lime is used to produce mortars and renders for building construction when mixed with sand and water. Hydraulic lime is a type of slaked lime that can set under water.
Professional ethics for architects and interior designers were discussed. The presentation defined ethics as moral philosophy involving concepts of right and wrong conduct.

• One-way slabs are those slabs with an aspect ratio in
plan of 2:1 or greater, in which bending is primarily
about the long axis. So, the slab is one way where
L/B ≥ 2.
• The Slab supported on two opposite side only in
which the structural action of the slab is essentially
one way.
• Direction of load carried by the slab is perpendicular
to the supporting beams.
• Slab depths are usually 4-10 inches (100-150mm).
• Uneconomical on spans of more than 20’(6000mm) .
9. Provides useful flat surface
One way slab may be used when
there is architectural limitations
It is the simplest form of slab
design
Main reinforcement placing is
one way, so there is a little
congestion than two way slab
APPLICATION OF ONE WAY SLAB
10. Two-way slab
There may be beams on all
four side , so two way slab
action is obtained.
Two-way slabs carry load in
two directions.
“Generally, two way floor
systems are more
economical than one-way
systems in buildings where
columns can be spaced in
bays that are square or
nearly square in proportion”
12. • In slab the corners may be held down by restraints or may be allowed to
lift up
• Additional torsion reinforcement is required at corners when it is
restrained against uplifting as shown .
13. Solid Flat Slab System.
• Floor systems can made without beams. Instead,
“the slab is reinforced in such a way that the varying
stresses in the different zones of the slab are
accommodated within a uniform thickness of
concrete”
• Slab depth =250 MM
• Suitable span 6 to 9m
Advantages
– Low cost formwork
– Exposed flat ceilings
– Fast
14. Disadvantages
•Due to continuous pressure at point (less surface area), it
create punching shear cracks at joints.
•Require more form work for panels and Capitals.
17. • “In more lightly loaded buildings, such as hotels,,
dormitories, and apartment buildings, the slab need
not be thickened at all over the columns.”
• Slab depth =.
• Suitable span 4.5m to 6.0m
Advantages
– Low cost formwork
– Exposed flat ceilings
– Fast
Disadvantages
– Low shear capacity
– Low Stiffness (notable deflection)
Flat Plate System
28. • Thickness of the slab is decided based on
span to depth ratio for mild steel bars.
• The maximum diameter of bar used in slab
should not exceed 1/8 of the total thickness
of slab
• Maximum spacing of main bar is restricted to
3 times effective depth or 300 mm which
ever is less
• For distribution bars the maximum spacing is
specified as 5 times the effective depth or
450 mm which ever is less
DESIGN CRITERIA FOR REINFORCEMENT
29. TYPES OF SLAB PROBLEM
Cracking Of The Slab
Damp Or Wet
Floor Slab
30. CRACKING OF THE SLAB : CAUSES
Inadequate structural strength of concrete
Improper placement of reinforcing & mesh
Poor construction
techniques and
practices
Differential / Uneven
settlement
31. Damp or Wet Floor Slab : Causes
Moisture migration through the slab
Poor site drainage
