Reliability assessment of concrete-filled steel tubular frames designed by advanced analysis

钢管混凝土结构由于具有高强度、高延性和大的能量吸收能力等优点，在高层建筑、桥梁等基础设施中得到越来越多的应用。本计画将评估以高阶分析法设计之钢管混凝土框架之系统可靠度。将研究载荷、强度、材料特性和几何特性的固有不确定性对这种框架的系统可靠性的影响。该项目的成果将用于制定基于可靠性的规定，以实现钢管混凝土结构设计的目标可靠性范围。

Concrete-filled steel tubular structures have been increasingly used in high-rise buildings, bridges and other infrastructure due to their enhanced properties such as high strength, high ductility and large energy absorption capability. This project will evaluate the system reliability of concrete-filled steel tubular frames designed by advanced analysis. The influences of inherent uncertainties in loads, strength capacities, material properties and geometric properties on the system reliability of such frames will be studied. The outcomes of this project will be used to develop reliability-based provisions to achieve a target reliability range in the design of concrete-filled steel tubular structures.
