## Analysis Methods for Buildings Frames

Elastic analysis deals with the study of strength and behavior of the members and structure at working loads. Frames can be analyzed by various methods. However, the method of analysis adopted depends upon the types of frame, its configuration (portal ...

## What is Shear Center – Location of Shear Center with Examples

Shear center is a point on the beam-section where the application of loads does not cause its twisting. The shear center position is dependent on the cross-section of the beam. For instance, shear center and center of gravity are the ...

## What is Tributary Area in Columns?

Tributary area is the area surrounding the column that is bounded by a panel centerline. In order to calculate the forces and static loads transferred from floor slabs to the columns tributary area method is used. Commonly, designers use tributary ...

## Modulus of Rupture of Concrete Beam

Modulus of rupture is a measure of the tensile strength of concrete beams or slabs. Flexural strength identifies the amount of stress and force an unreinforced concrete slab, beam or other structure can withstand such that it resists any bending failures. ...

## Assumptions in Strength Calculation of Building Materials with Explanations

Strength, resistance against failure is the important property of any civil engineering material. Every material is to be tested for its strength before going to use it. There are various external forces which acts on materials in different ways. To ...

## Stress in Structural Materials, Their Types and Sign Conventions

Stress is resistance provided by structural material against deformation. Stress is measured in terms of load per unit area and is expressed in MPa or N/mm2. Types of stresses and their sign convetions for calculations are discussed.

## Types of Supports and Reactions and Their Applications in Structures

Support in a structure is a member which helps others member to resist loads. Different types of supports, their reactions and applications in structures.
