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.

在这项研究中，研究了钢制建筑结构中“无焊”柱对梁半刚性连接的可行性。研究了以下两个主题：（1）与高层建筑物的无符号连接的可行性，（2）具有焊接连接的钢框架结构设计的可能性。对于拳头，通过加载测试和数值模拟研究了高层建筑物中无性梁末端连接的局部行为。根据实验和分析研究，确定柱压缩的轴向压缩比对连接强度几乎没有影响。对于第二个主题，研究了无焊接连接到具有增强膝盖括号的多层建筑结构的应用。子组合装载测试表明，塑料铰链位置可以通过膝盖括号的设计来控制。进行了低层建筑的示例设计。
