摘要
介绍了杆系结构动力响应的弹性波分析的方法——回传波射矩阵法 ,并将其应用于受阶跃函数加载的钢屋架的瞬态响应分析 .与有限元法进行比较 ,结果表明 ,用弹性波方法所得到的动态响应含有丰富的高频分量 。
The reverberation ray matrix method, proposed by Pao, et al. to analyze the dynamic response of truss type structures in terms of wave propagation, was introduced and used to investigate the transient response of a steel roof truss subjected to a step load. Comparing the results with the conventional finite element method, it is found that the transient response of elastic wave method contains rich higher frequency components, providing a more accurate description of the transient process.
