摘　　要：在对预应力混凝土十字形柱框架结构非线性有限元分析理论进行研究后,得到了能描述预应力混凝土十字形柱框架结构工作时的受力及变形性能的方法,用FORTRAN90编制相应的计算程序。用该程序在计算机上进行大量的计算分析,分别在各种不同方式荷载作用下和不同的柱截面、跨度、柱纵筋量、梁预应力筋量等因素的情况下,对预应力混凝土十字形柱框架结构体系结构性能进行了探讨研究,使得在设计工程中能有所把握。After nonlinear finite analysis theory on prestressed concrete frame with cross section column was studied,a method to describe the mechanical feature of a working prestressed concrete frame with cross section column was obtatained.And the computer programme was designed with FORTRAN90.Then the structure feature of prestressed concrete frame with cross section column was analyzed and discussed with various kinds of loading and with defferent factors such as column section?span?quantity of steel in column?quantity of prestress steel in beam by plenty of result of calculating with computer.That will do great help when in design.
