摘要: 在对预应力混凝土十形柱框架结构的非线性有限元分析方法进行了深入研究后,得到了能较正确、全面描述预应力混凝土十形柱框架结构工作性能的方法,用FORTRAN90编制得到相应的计算程序。用该程序在计算机上进行大量的计算分析,将预应力混凝土十形柱框架结构性能与矩形柱框架结构性能进行了比较研究,得到这两种结构各自的特点。Abstract: After nonlinear finite analysis method on prestressed concrete frame with cross column was studied, a quite correct and general method to describe the mechanical feature of a working prestressed concrete frame with cross column was obtained. And the computer programme was designed with FORTRAN90. After the programme was validated, the structure feature of prestressed concrete frame with cross column was compared with that of prestressed concrete frame with rectangular column by plenty of results by computer. Then the characteristics of the two structures are obtained.
