西安兴教寺塔抗震性能分析
|
摘要
为了对国家现存文物-砖石古塔进行有效的抗震保护,结合砖石古塔的震害规律,采用振型分解法对陕西省西安市兴教寺塔进行了抗震性能研究.结果表明,西安市兴教寺塔的各层抗震承载力均不够充裕,竖向地震作用下的抗震能力满足要求,塔的中轴面抗剪强度不足.这可作为有关部门古建保护的参考依据.
To carry on the effective seismic protection for the extant national cultural relic-masonry pagoda,with the earthquake damage rule,the study on the seismic performance of Xingjiao pagoda in Xi'an,Shaanxi Province has been done by mode-superposition method.The results indicate that seismic resistance of each floor of Xingjiao pagoda is insufficient,the seismic resistance capacity subjected to vertical seismic action satisfies the requerments,the shear strength of the pagoda medial axial surface is inadequate.This conclusion can be as relevant reference for the protection of ancient buildings.
