This paper mainly focused on some basic research as follows:(1) ANSYS finite element calculation software and the APDL design language were used to set up two model structures—the reinforced concrete floor model and the prestressed space composite trass model.

本文就该结构做了以下几点基础性研究工作：(1)利用ANSYS有限元分析软件和APDL参数设计语言建立了两个模型：钢筋混凝土楼板模型和预应力空间组合结构模型，对楼板模型和预应力空间组合结构模型分别进行了非线性静力分析，模态分析和竖向动力荷载下的非线性瞬态分析，并对两种结构的力学行为做了比较，得到了一些初步结论。
