Reliability and full-range analysis of joints in steel frameworks

该项目有两个主要组成部分，即建立一个以力学为基础的非线性模型，用于在结构分析中表示接头，以及考虑构件和接头强度和行为随机性的系统级可靠性框架。作为其主要目的，该项目旨在为在结构工程界引入基于计算机的钢框架直接设计铺平道路，从而消除了根据结构标准检查构件和接头强度的需要。直接设计方法比目前的设计实践更准确、更经济、更快，提供更统一的结构系统可靠性，并鼓励结构和建筑形式的创新。

The project has two main components, namely to establish a mechanics-based nonlinear model for representing joints in structural analyses, and a reliability framework at system level that considers randomness in the strength and behaviour of both members and joints. As its main aim, the project aims to pave the way for introducing computer-based direct design of steel frames in the structural engineering community, thus obviating the need for checking member and joint strengths to a structural standard. The direct design approach is more accurate, economical and faster than current design practice, provides more uniform structural system reliability, and encourages innovation in structural and architectural forms.
