结合工程实例,对框排架结构进行了动力分析,评估了框排架结构的安全性和抗震性能。研究表明,框排架结构存在平面布置不规则、竖向布置不规则以及扭转效应等,总体上不利于抗震。提出了设计思路和增设屈曲约束支撑的处理措施,使其满足现行抗震规范的要求,方法可供同类工程参考。
Combined with the engineering examples, the dynamic analysis of the frame-framed structure was carried out to evaluate the safety and seismic performance of the frame-framed structure. The research shows that the framed structure has irregular layout, irregular vertical arrangement and torsional effect, which are not conducive to earthquake resistance. Proposed design ideas and additional buckling restraint support measures to meet the requirements of the current seismic code, the method for similar projects for reference.
