I. Cyclic loading test of subassemblage specimens with semi-rigid connections using high-strength boltsIn order to experimentally investigate structural behavior of steel frame with semi-rigid connections, cyclic loading tests were performed for subassemblage specimens; the semi-rigid connection considered in this study consists of split-T stub and high-strength bolt connections. Column sections of the subassemblage specimens are square hollow section or H-shaped one, which are generally used for lowrise steel buildings.II. Numerical simulation of structural behavior of semi-rigid connection using high-strength boltsYield and ultimate strength of the semi-rigid connection is well predicted by yield line theory with assuming appropriate mechanism. Structural behavior of tested subassemblages are also numerically simulated by FEM analysis. The bending moment-rotational angle relationships of the semi-rigid connections are modeled as nonlinear rotational springs at beam ends by using the analytical results.III. Perfomace-baced design scheme of small steel buildings with semi-rigid connectionsAccording to the above study results, performace-baced design scheme of small steel building is introduced. In this design scheme, criteria for design of semi-rigid connection is presented, depending upon level of seismic load and whether the connection is full-strength or partial-strength.

I.为了研究半刚性连接钢框架的结构性能，对T形接头和高强螺栓连接的半刚性连接进行了低周反复荷载试验。组合试件的柱截面为方形空心截面或H形截面，一般用于低层钢结构建筑。高强螺栓半刚性连接结构性能的数值模拟采用屈服线理论，通过合理的机理假设，较好地预测了半刚性连接的屈服和极限承载力。试验组件的结构行为也通过有限元分析进行了数值模拟。利用分析结果，将半刚性连接节点的弯矩-转角关系模拟为梁端的非线性转动弹簧。基于上述研究成果，提出了半刚性连接小型钢结构房屋的性能化设计方案。在该设计方案中，半刚性连接的设计准则，根据地震荷载的水平，无论是全强度或部分强度的连接。
