摘要
用蒙特卡罗法和响应面法计算风荷载作用下型钢混凝土结构侧移控制的失效概率及其可靠指标时,蒙特卡罗法需要循环模拟次数太多,而响应面法无法准确求出小失效概率,提出的假定位移分布模式的直接积分法能较好地解决此问题.可靠度分析结果表明,现行《规程》可靠指标偏低.
<Abstrcat> When computing the invalid probability and reliability for SRC struc ture based on peak displacement under wind load by MC method and response surf ace method,MC method needs lots of calculating time and response method is incapable of computing little invalid probability accur ately occur. So direct integral method based on displacement model is brought o ut.
