ENHANCING THE SEISMIC RESPONSE OF A MULTIFUNCTIONAL STADIUM EQUIPPED WITH LRB ISOLATORS UNDER NEAR-FIELD EARTHQUAKES

Abstract

Disasters have always coexisted with civilization, and it is impossible to prevent earthquakes from occurring; however, it is possible to reduce the effects and decrease the loss of life, as well as injuries and damage to structures and infrastructure facilities. Investigating the safety of crowded places, such as stadiums, where many people gather for special events is of utmost importance. One of the most effective methods to counter an earthquake’s force is the use of seismic isolators. Therefore, the seismic performance of a multifunctional stadium with and without lead rubber bearings (LRBs) during near-field earthquakes was studied in this research. It was found that the seismic isolators dissipated the input earthquake energy, and the isolated stadium received less base shear force and drift during the earthquake. It was observed that adding seismic isolators to the stadium had a significant positive effect on its behavior, and this technique is highly recommended to ensure residents’ safety in near-field regions.
