Types of Supports for Loads | Roller, Hinge, Fixed
Roller supports are free to rotate and translate along the surface upon which the roller rests. The surface may be horizontal, vertical or slopped at any angle. Roller supports are commonly located at one end of long bridges in the form of bearing pads. This support allows bridge structure to expand and contract with temperature changes and without this expansion the forces
Frame Structures - Types of Frame Structures
Frame structures are the structures having the combination of beam, column and slab to resist the lateral and gravity loads. These structures are usually used to overcome the large moments developing due to the applied loading. Types of Frames: Frames structures can be differentiated into: 1. Rigid frame structure Which are further subdivided into:Pin ended, FixedDesign & Analysis of Slab in SAP2000

Bending moment at a point or at a section is the algebraic sum of Moments caused by forces action to the left or right of that point or section. Mathematically it can be written as
Analysis of Statically Indeterminate Beams by Force Method
While analyzing indeterminate structures, it is necessary to satisfy (force) equilibrium, (displacement) compatibility and force-displacement relationships. Force equilibrium is satisfied when the reactive forces hold the structure in stable equilibrium, as the structure is subjected to external loads. Displacement compatibility is satisfied when the various segments of the
Analysis & Design Report for Store & Generator Room
It is a frame structure single storey unit & includes areas for various purposes, such as transformer generator space. Ultimate Strength Design (USD) or Load and Resistance Factors Design (LRFD) method is used for structural design of all the components. The concrete used for all structural members should have a minimum 28 days cylinder crushing strength of 3,000 Psi.
Approximate Analysis of Indeterminate Structures
Conventional design process is normally based on the ‘local’ structural elements (column, beam, floor slabs, wall, etc.) But theoretical and experimental studies have shown that structural systems cannot be considered to be a simple collection of individual elements. The responses of the structure is often more than the ‘sum’ of the responses of individual elements sinceFrame Design and Analysis using SAP2000

Advantages and Limitations of Prestressed Concrete
The pre-stressing of concrete has several advantages as compared to traditional reinforced concrete (RC) without pre stressing. A fully prestressed concrete member is usually subjected to compression during service life. This rectifies several deficiencies of concrete. The following text broadly mentions the advantages of a pre-stressed concrete member with an
Minimum Steel Reinforcement in Concrete
The minimum amount of steel reinforcement is defined as that for which "peak load at first concrete cracking" and "ultimate load after steel yielding" are equal. In this way, any brittle behavior is avoided as well as any localized failure, if the member is not over-reinforced. In other words, there is a reinforcement percentage range, depending on the size-scale,
Concrete Shear Wall Strength and Properties
Shear wall is a structural member used to resist lateral forces i.e parallel to the plane of the wall. For slender walls where the bending deformation is more Shear wall resists the loads due to Cantilever Action and for short walls where the shear deformation is more it resists the loads due to Truss Action. These walls are more important in seismically active zones because
Excess Steel Reinforcement: Problems and Remedies
Reinforcement is generally put into concrete to cater for its relative weakness in tension compared with compression. The term 'cross-sectional area' (CSA) is used to refer to the area of the section under consideration, both for the concrete and for the steel. The ratio of the area of the steel to that of the concrete is the percentage of reinforcement, which for concrete
