古代石塔地震安全性评价研究——以清净化城塔为例
|
摘要
本文采用反应谱分析法对西黄寺清净化城塔进行了地震安全性分析,找出其薄弱环节,得出对其结构抗震安全性评价有价值的结论。目前的反应谱分析多般基于线弹性应力应变模型,但结构一旦出现开裂,结构的应力应变关系将是非线形性的,若求解开裂结构的位移和应力,反应谱分析不再适用。但反应谱分析结果能够帮助分析人员找出结构的薄弱环节,判断结构在关键部位是否会出现裂缝以及其定性地判定裂缝开展的程度。从这个意义上讲,反应谱分析对结构的抗震分析具有重要的作用。
In this paper,the seismic Stability of the Qingjinghua Pagoda in Xihuang Monastery is analyzed with response spectrum,in order to identify its weaknesses,with valuable findings about its structure' s seismic stability.In this paper,the multi-event and the rare case of response spectrum on the pagodaare introducedto the seismic analysis.The current response spectrum analysis is usually basedon linear elastic stress-strain model,but with the event of cracking of structure,the structure of the stress-strain relationship will be non-linear in nature, so that theresponse spectrum analysis is no longer applicable to solve the displacement and stress of cracking structure.However,the results of response spectrum analysis can help analysts to identify weak links in the structure to determine whether the concerned parts of the structure emerge cracks,and to measure the extent of the cracks.In this sense,the response spectrum analysis is contributory to the seismic analysis of the structure.
