摘要
考虑节点剪切变形和二阶效应的影响 ,提出了建立在带半刚域杆元二阶分析基础上的钢框架结构自由振动分析方法 ,同时 ,进行了 5层足尺钢框架结构的动力试验。通过与试验结果的比较 ,表明该方法的分析结果准确性高 。
Based on the second\|order analysis of the beam element with semi\|rigid regions at ends,a new method of the free vibration analysis of steel frame structures is developed,which accounts for the second\|order effect and the joint shear deformation.A full\|scaled 5\|storey steel frame structure is tested for investigating its dynamic characteristics.The calculation values from the new method are compared with the test results,which shows a very good accuracy.Other example problems are also analyzed by the new method and other methods for further comparison.
