Reliability and Risk-Based Design of Stuctures Under Multiple Hazards

人们越来越需要一种对关键结构进行安全和性能评估的方法，其中载荷组合效应很重要。 在许多情况下，结构所承受的动载荷在时间和空间上是随机的。 它们对结构可靠性的单独和综合影响不容易评估。 该项目研究荷载组合分析和设计的概率方法。 该研究将强调所开发的方法在设计中的应用。 主要研究任务包括：开发基于结构优化的设计方法、开发计算效率高的非线性组合问题的一阶和高阶方法、评估当前设计方法和开发替代设计公式。

There is an increasing need for a methodology for safety and performance evaluation of critical structures in which loads combinations effects are important. In many cases, dynamic loads to which a structure is subjected are stochastic in time and space. Their individual and combined effects on the reliability of structures are not easy to assess. This project investigates the probabilistic methods for load combination analysis and design. The study will emphasize the application of the methodologies developed to design. The major research tasks include: development of methods for design based on structural optimization, development of computationally efficient first and higher order methods for nonlinear combination problems, and evaluation of current design methods and development of alternative design formula.
