摘要: 在深入研究预应力混凝土T型柱框架结构非线性有限元分析理论后,得到了描述预应力混凝土T型柱框架结构工作性能的方法,用FORTRAN 90编制相应的计算程序。用该程序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T型柱框架结构体系结构性能进行了探讨研究。可为设计工作提供参考。Abstract: After nonlinear finite element analysis theory on prestressed concrete frame with T-section column was studied,a method to describe the mechanical feature of a working prestressed concrete frame with T-section column was obtained.And the computer programme was designed with FORTRAN 90.Then the structure feature of prestressed concrete frame with T-section column was analyzed and discussed under various kinds of loadings and with different factors such as column section,span,quantity of steel in column and quantity of prestress steel in beam by plenty of results of calculating with computer.That will do contribution to design.
