| 摘 要： | 首先介绍了基于首超破坏准则和改进的一次二阶矩方法的可靠度计算,并给出了随机参数灵敏度的近似估算方法,比较了风、地震作用下,实际多高层结构的可靠度。分析说明,基于概率理论的可靠度比较,与基于响应量的直接比较不完全的相同,由于结构可靠度的比较可能涉及到响应控制阈值,结构系统的参数随机性等,因此可靠度的比较有其自身的特点。 |

| Abstract: | The reliability computations based on the first cross failure criterion and first order secondary moment are introduced and approximate computations of parameter sentivity are presented.Then several examples of reliability comparison of multi tall building structures are illustrated.The analysis shows that the reliability comparison is of special character and definite difference as compared with the direct response comparison due to the response valve and system parameters randomness. |
| Keywords: | reliability first-cross failure Jc method wind earthquake |
