Pushover analysis for cold formed storage rack structures

الملخص EN

This study investigated the progressive collapse of cold formed storage rack structures subjected to seismic loading, using pushover analysis.

A simple storage rack cold formed steel structure was analyzed with static, non-linear procedure in accordance with FEMA 356 specifications and progressive collapse recorded such as occupancy, immediate occupancy, life safety and collapse prevention.

Pushover analysis was found to be a useful analysis tool for the conventional storage racking systems giving good estimates of the overall displacement demands, base shears and plastic hinge formation.
