【摘要】 对预应力混凝土T形柱框架结构的非线性有限元分析进行了深入的研究后,得到了能较正确、全面描述预应力混凝土T形柱框架结构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,将预应力混凝土T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,得到这两种结构的优缺点。更多还原

【Abstract】 After nonlinear finite analysis method on prestressed concrete frame with T-section column was studied,a quite correct and general 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 FORTRAN90.Then after the programme was validated,the structure feature of prestressed concrete frame with T-section column was compared with that of prestressed concrete frame with rectanglular section column by plenty of result of calculating with computer.Then obtained their merit and shortcoming according to the result of study.更多还原
