| Research Abstract |
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.
