Many buildings in the present days have irregular shapes in both elevation and plan. Past earthquake studies show that buildings suffer severe destruction during earthquakes due to torsional irregularity.When and how to consider torsion effects is depended on the criterion andrelative restrictions for torsional irregularity. Relationship between the degree of irregularity and the change in behavior could developed which allows guidance as to a) When the effect of structural irregularity can be…

Earthquake induced torsion in buildings:critical review and state of the art
The problem of earthquake induced torsion in buildings is quite old and although it has received a lot of attention in the past several decades, it is still open. This is evident not only from the
Evaluation of Torsional Provisions in Seismic Codes
The effects of plan asymmetry on the earthquake response of code-designed, one-story systems are identified with the objective of evaluating how well these effects are represented by torsional
Effects of Building Configuration on Seismic Performance of RC Buildings by Pushover Analysis
In the recent earthquakes, concrete structures have been severely damaged or collapsed, which has raised questions against the seismic adequacy of existing buildings. These existing reinforced
