Abstract This study presents the details of experimental investigations on a novel energy dissipative beam-column connection. This work is in line with the current research focused on developing resilient structures by confining inelastic actions or damage within easily replaceable select number of elements in a structure at predetermined locations. Towards this, a novel connection consisting of two fuse links and a standard shear tab is developed such that the beam, column, shear tab and connecting bolts remain elastic, while sufficient energy dissipation is provided by the fuse links alone. The experimental programme entails component level tests on fuse plates and full-scale exterior beam-column joint sub-assemblage studies by using the novel connection to demonstrate its performance and to prove its efficacy. For this purpose, monotonic and standard pseudo-static reversed cyclic loading protocol is used. It is observed that the connection exhibits good energy dissipation characteristics by confining the damage within the fuse links keeping the primary structural members in elastic state. The same column and beam sections are used for all the experiments as no damage is observed, except bolt thread marks in beam. Also, a damaged connection could be easily dismantled within about 10–15 min and replaced with a new one.

抗震框架的耗能梁柱连接

摘要 本研究详细介绍了新型耗能梁柱连接的实验研究。这项工作与当前的研究一致，该研究侧重于通过将非弹性作用或损坏限制在预定位置的结构中易于更换的选定数量的元件内来开发弹性结构。为此，开发了一种由两个熔断体和一个标准剪力片组成的新型连接，使得梁、柱、剪力片和连接螺栓保持弹性，而单独的熔断体提供足够的能量耗散。实验计划需要对保险丝板进行组件级测试，并通过使用新型连接来展示其性能并证明其有效性，从而进行全尺寸外部梁柱接头子组件研究。以此目的，使用单调和标准的伪静态反向循环加载协议。可以观察到，通过将损坏限制在熔丝链内，使主要结构构件保持在弹性状态，该连接表现出良好的能量耗散特性。除了梁中的螺栓螺纹标记外，所有实验都使用相同的柱和梁截面，因为没有观察到损坏。此外，损坏的连接可以在大约 10-15 分钟内轻松拆除并更换新的。除了梁中的螺栓螺纹标记。此外，损坏的连接可以在大约 10-15 分钟内轻松拆除并更换新的。除了梁中的螺栓螺纹标记。此外，损坏的连接可以在大约 10-15 分钟内轻松拆除并更换新的。
