The limit state design is to be in practice. The evaluation of the limit state and quantitative description of performance of connections are essential in structural design of steel constructions. Three major items of research are in this project :(1) The quantitative description of connection behavior in steel structures and mixed structures. The semi-rigid connections are included in these categories.(2) The loading load speed effect on inelastic behavior and fracture.(3) Causes of fracture in welds in connections and structural design method taking into account occurrence of fracture around connections.Experimental studies and theoretical approaches were carried out in several academic institutions for past three years. The outcomes of above research items were fully discussed by the project members each year. In the end of the project, these results were summarized and discussed by participants in the seminar.

极限状态设计要付诸实践。极限状态的评估和连接性能的定量描述在钢结构结构设计中至关重要。本课题主要研究三项内容：（1）钢结构及混合结构连接行为的定量描述。半刚性连接包括在这些类别中。（2）加载速度对非弹性行为和断裂的影响。（3）连接焊缝断裂的原因以及考虑连接周围断裂发生的结构设计方法。实验研究过去三年来，多个学术机构开展了理论研究。上述研究项目的成果每年都经过项目成员的充分讨论。在项目结束时，研讨会参与者对这些成果进行了总结和讨论。
