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.

钢管混凝土结构由于具有高强度、高延性、大吸能等增强性能，在高层建筑、桥梁等基础设施中得到越来越多的应用。本项目将对设计的钢管混凝土框架进行系统可靠性评估。研究了荷载、强度、材料性能和几何性能等固有不确定性对框架系统可靠性的影响。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度范围。
