Application of Buckling Constrained Bracing in Reinforcement Engineering of Open Building Structures
Buckling restrained braces,abbreviated as BRBs,have been widely used in new buildings after nearly 50 years of development and have been proven to have significant earthquake resistance and disaster reduction effects in multiple earthquakes both domestically and internationally.Compared to new construction projects,reinforcement and renovation projects have more constraints.In order to achieve eco-nomic and feasible goals in structural seismic reinforcement design,the application of seismic reduction components such as buckling re-strained braces has gradually increased in reinforcement and renovation projects in recent years.This article takes the reinforcement and renovation project of a theater in Xiamen as an example,compares the structural forms before and after adding buckling restrained braces,explores the practical application of buckling braces in the reinforcement and renovation of open buildings,and aims to provide reference for similar engineering projects.
