In this study, feasibility of "weldless" column-to-beam semi-rigid connection in steel building structures is investigated. The following two subjects are studied : (1) feasibility of the weldless connections to high-rise buildings, (2) possibility of structural design of steel frameworks with the weldless connections. For the fist subject, the local behavior of the weldless beam-end connection in a high-rise building is investigated by loading tests and numerical simulations. According to the experimental and analytical investigations, the axial compressive ratio where the compression of the column has little effect on connection strength is determined. For the second subject, the applications of the weldless connections to multi-story building structures with reinforcing knee braces are studied. Subassemblage loading tests show that plastic hinge positions can be controlled by knee braces' design. Example designs of low-rise buildings are conducted.

本研究主要探讨建筑钢结构梁柱半刚性连接节点“无焊缝”的可行性。本文主要研究了以下两个问题：（1）高层建筑无缝连接的可行性;（2）高层钢框架无缝连接结构设计的可行性。第一个课题是通过荷载试验和数值模拟，对某高层建筑梁端无焊缝节点的局部受力性能进行研究。根据试验和分析结果，确定了柱的受压对节点强度影响不大时的轴压比。第二个课题研究了无焊缝节点在带加强支撑的多层建筑结构中的应用。拼装式加载试验表明，塑性铰的位置可以通过肘撑的设计来控制。进行了低层建筑的实例设计。
