【摘要】:為了研究地震對儲罐造成的影響,結(jié)合歷史上儲罐的震害資料,將儲罐的損傷程度進行分級,通過采用Bayes方法估計Probit模型參數(shù),再轉(zhuǎn)化成儲罐的損傷概率,給出了各個損傷狀態(tài)下的模型參數(shù)及給定地震加速度下儲罐的損傷概率,提出了1種基于Probit-Bayes方法估計儲罐易損性的計算方法。結(jié)果表明:所提出的地震損傷計算方法,能夠有效的評估儲罐在不同地震加速度下的損傷程度,可為震后儲罐的安全評估提供理論依據(jù)。
[Abstract]:In order to study the influence of earthquake on storage tank, combined with the earthquake damage data of storage tank in history, the damage degree of storage tank is graded, and the parameters of Probit model are estimated by Bayes method, and then transformed into the damage probability of storage tank. The model parameters under each damage state and the damage probability of the tank under given seismic acceleration are given, and a calculation method based on Probit-Bayes method to estimate the vulnerability of the tank is proposed. The results show that the proposed seismic damage calculation method can effectively evaluate the damage degree of the storage tank under different seismic acceleration, and can provide a theoretical basis for the safety assessment of the storage tank after the earthquake.
