Natural vibration analysis of stiff cable structures;
劲性索结构固有振动分析
Natural vibration of stiff cable structures is analyzed based on FEM and the energy variation method,and the same is done to truss arch structures based on the new concept of upset stiff cable, from which the similarities of the two types of structures are obtained.
采用有限元法对劲性索结构及由其倒置而成的桁架拱结构进行了固有振动分析,并与采用能量变分法对这2类结构固有振动分析得到的结果进行了比较,得到劲性索及桁架结构的固有振动具有相似性。
