| 摘 要： | 基于撑杆式预应力钢压杆正对称和反对称两个基本屈曲模态, 给出了相应的屈曲形态函数, 通过3个典型算例并变化关键参数着重研究了模拟曲线项数, 同时给出了不对称屈曲的形态函数. 研究表明, 取形态函数模拟项数为预应力钢压杆节间数, 可以很好满足工程精度.

| Abstract: | The mode function is the key for obtaining the critical load of astayed steel column. Based on two basic modes, symmetric and anti-symmetric,the basic buckling mode functions are obtained, and three examples areconsidered for the performance of simulation curves by varying their keyparameters. At last, the buckling mode function for asymmetric bucklingis obtained. The results indicate that the engineering requirements canbe met when the number of simulation curves is equal to the total sectionnumber of the stayed steel column. |
