| 摘 要： | 本文主要以某拟建工程为例,采用Midas/gen大型有限元软件,对新型钢筋混凝土空间网格盒式“成束筒”结构进行大震下的静力弹塑性分析,从层间位移曲线、层间位移角曲线和塑性铰分布等方面对结构的抗震性能进行综合的评估,并揭示出结构的薄弱处.计算结果表明,该新型结构符合“强柱弱梁”的原则,能够满足“大震不倒”的抗震设防要求.

| Abstract: | Taking a proposed project as an example, a new structure called RC spatial grid cassette ＂ bundled tube＂ structure was analyzed by pushover analysis under strong earthquake with Midas/gen. The study proves that the storey drift curve, the storey drift angle curve and the distribution of plastic hinges are obtained to give a general assessment of the new structure and reveal the weak points of the structure. The results show that the new structure conforms with the principle of strong-column-weak-beam and will not collapse under strong earthquake. |
