本文主要以某拟建工程为例,采用Perform-3D软件对新型钢筋混凝土空间网格盒式“成束筒”结构进行大震下的动力弹塑性时程分析,得到各地震波下的楼层位移、层间位移角和楼层剪力,并对结构进行性能分析。结果表明,在大震作用下,该结构仍具有较好的刚度,大部分构件处于弹性阶段,可满足所设定的性能目标。 Taking a certain project as an example, this paper uses Perform-3D software to analyze the dynamic elasto-plastic time-history of the new reinforced concrete space lattice box-type “beam-tube” structure under large earthquakes. Displacement, drift angle and floor shear, and analyze the structure performance. The results show that under the action of large earthquake, the structure still has good rigidity, most of the components are in the elastic phase, which can meet the set performance targets.
