## How to Determine Torsional Irregularities in Buildings

One of the code requirements in structural analysis is to review the structural arrangement of the elements as a whole for any type of building irregularities. The most popular among these types and perhaps the most complex is…

## Scaling of Base Shear Results of Static and Dynamic Analysis

Base shear is an estimate of the maximum expected lateral force that will occur at the base of the structure due to the seismic ground motion. During the analysis, the codes required for the use of the equivalent…

## Basics of Diaphragm Action

DIAPHRAGM DIAPHRAGM is horizontal or nearly horizontal system acting to transmit lateral forces to the vertical resisting elements. The term “diaphragm” includes horizontal bracing systems. There are two popular types of diaphragm namely rigid diaphragm and semi-rigid Diaphragm. The…
