Finite element analysis using Staad-Pro for irregular L-shape Building by Time History Analysis

Abstract

To perform well in an earthquake, a building should possess four main attributes, namely
simple and regular configuration, and adequate lateral strength, stiffness and ductility.
Buildings having simple regular geometry and uniformly distributed mass and stiffness in
planes well as in elevation, suffer much less damage than buildings with irregular
configurations. Impairment can be in the form of loss of non-structural element, damage to
structural components, and collapse of structural element leading to progressive failure of
section or whole building. This failure usually happens in a domino effect and leads to a
progressive collapse failure in the construction.
The Linear Static Analysis is carried out by using STAAD-PRO software. From the results
obtained, it is observed that the vulnerability of a multi-storey structure is least for a low
intensity blast generated at a comfortably longer standoff distance.
