| Research Abstract |
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.
