基于蒙特卡罗法的钢筋混凝土柱抗震可靠度分析
|
摘要
近年来各国地震的频繁发生,使基于建筑结构更具安全性的抗震可靠度研究计算方法备受关注。根据我国现行抗震规范的要求,运用蒙特卡罗法理论,对同一钢筋混凝土柱分别基于极限承载力和位移两种方法进行抗震可靠度分析,并比较不同偏心率下柱的抗震可靠度变化。计算结果表明:相同条件下基于位移的抗震可靠度值偏小;地震作用下的结构可靠度并非完全取决于构件的强度,还与构件的变形能力相关;采用位移可靠度分析方法控制构件抗震可靠度更为合理。
In recent years,the earthquakes occurred frequently in all over the world,the seismic reliability of calculation methods based on building structures more security is concerned.According to the requirement of current seismic code in our country,this paper analyses the seismic reliability of the same reinforced concrete column based on ultimate bearing capacity and displacement method by using Monte Carlo Method theory,and compares the change of seismic reliability on frame column under different eccentricity.The calculation result shows that the value of seismic reliability based on displacement under the same condition was small;The structural reliability under the influence of earthquake did not completely depend on the strength of component,which was also related with the deformation ability of component;The method of displacement control seismic reliability was more reasonable.
