摘要
针对某三层钢框架结构,通过底部剪力法与符合规范的手算方法相比较,验证了SAP2000结构模型的可靠性;采用三种侧向荷载加载方式分别对结构进行了Pushover分析,对结构抗倒塌性能水准进行了划分,并对原结构设计给出了优化建议.结果表明:在罕遇地震作用下结构处于弹性状态,结构抗震性能良好,原结构设计具有进一步优化的空间.
The principle and operating steps of pushover method are presented, and it is applied to one three-sto- rey steel frame structure. The comparison between equivalent base shear method with SAP2000 and manual com- putation in the book verifies finite element model in SAP2000. Then pushover analysis is carried out in detail with three different loading patterns, performance levels during structural anti-collapse are classified, and suggestions for optimization are put forward. The results indicate that this structure stays elastic under rare earthquake, and it can be optimized further.
