摘　　要：考虑预应力混凝土空心板的构造特点 ,推导了进行板内力分析的各向异性有限元法公式。用在此基础上编写的壳体有限元分析程序进行算例比较 ,说明了采用各向异性四边形壳体有限元分析现浇预应力混凝土非规则空心楼板的必要性与可行性。In order to design irregular prestressed concrete floor, formulas of anisotropic finite element method to analyze the internal force of prestressed concrete hollow slab have been presented. At last, practical examples of cast-in-place prestressed concrete floors have been checked with the program Pres-Hift compiled with anisotropic shell finite element method to verify its necessity and feasibility.
