Simulation performance of low damage base connection on Abaqus

Current design codes can provide life safety performance level based on observations from recent earthquakes. However, buildings experience some damage that could be very costly to recover. Low damage control systems have been developed in recent years to minimize damage in severe earthquakes. The a...

The aim of this study is to improve the understanding of the performance of low damage steel structures especially in regard to column base connections and the friction connection with Grade 8.8 bolts.
