| 摘 要： | 针对在计算模型中可以用梁单元来描述的钢框架结构，本文运用ＳＡＰ５有限元计算程序，进行了大量的计算分析。在此基础之上，总结了单元划分的特点、结构的变形特征及水平地震动作用下结构动力反应中的振型参与情况，并给出了相对计算误差作为检验。本文最后计算了一个有实测数据的高２２ｍ的复杂钢框架。这一工作为有效地完成钢框架震害预测中的结构计算分析，提供了一定的初步经验。

| Abstract: | In this paper,numerous calculations and analyses are conducted by means of afinite element program of code-SAP5 for steel frame structures which may be divided intobeam elements in calculation models.On this basis,the characteristics of element discretionand structural deformation are summarized,and the influence degrees of different vibrationmodes on the dynamic responses of structures under the horizontal earthquake motion arepresented with relative errors calculating.Finally as an examination,a practical steel framewith a height of 22 meter and other measured values is analyzed.This research presents somepreliminary experiences for the structural calculation and analysis in the earthquake damagepredction of steel frames. |
