Structural Analysis, which is an integral part of any structural engineering project is the process of predicting the performance of a given structure under a prescribed loading condition. The performance characteristics usually of interest in structural design are
a. Stresses or stress resultants (i.e. axial forces, shear forces and bending moments)b. Deflectionsc. Support reactions
Thus the…
What is the difference between working stress approach and limit state approach?
February 27, 2016
For working stress approach, service loads are used in the whole design and the strength of material is not utilized in the full extent. In this method of design, stresses acting on structural members are calculated based on elastic method and they are designed not to exceed…
Type of beams, Cantilever, Simply Supported, Overhanging, Fixed, Continuous, Propped Cantilever Beam
December 25, 2015
A lot of times, while solving structural engineering problems, we found difficulty in understanding different types of beams.
This is very crucial to understand because different types of beams have different types of internal stresses and reactions to solve.
As explained…
A beam transfers the load to the supports that in actual might be a column or a wall which in turn transfers the load to the foundation.
Different Type of Structure / Beam Supports
The supports are actually the conditions in which this load is distributed. The supports that are normally used in a beam are ;-
a) Roller Supportb) Hinge or Pin Supportc) Fixed Support
Roller Support
Roller Support…
The algebraic sum of the vertical forces at any section of a beam to the right or left of the section is known as shear force. It is briefly written as S.F.
The algebraic sum of the moments of all the forces acting to the right or left of the section is known as…

Prior to the development of quantitative structural theories in the mid-18th century and since, builders relied on an intuitive and highly developed sense of structural behavior. The advent of modern mathematical modeling and numerical methods has to a large extent replace…
