摘要
提出了一种改进的建筑结构分析算法,在建立建筑结构动力分析的二阶传递矩阵模型基础上,应用传递矩阵算法于建筑结构的固有频率和固有振型计算,得到了与实验测试相一致的结果.通过分析,说明传递矩阵法应用于建筑结构分析是正确可靠的,且具有运算量小、速度快捷。
In this paper,an improved algorithm of building structural dynamic analysis was presented.The two ranks′ transfer-matrix model of building structure was built according to the shear layer model,then the transfer-matrix algorithm was applied in calculating building structural natural frequencies (or natural periods) and natural mode shapes.The computing result was in accordace with the experimental value obtained by the transient exciting test.By comparison it is proved correct,reliable and having high efficiency for the transfer-matrix algorithm to be applied in computing building structural natural properties.
