ABSTRACT In modular construction, individual modules are constructed at a controlled industrial environment before being transported to site. They are then connected horizontally and vertically to form a structure. The vertical connections can be achieved by welding or bolting the columns of stacked modules. This study investigates the seismic performance of modular steel-braced frames (MSBFs) connected vertically using superelastic shape memory alloy (SMA) bolts. The study also identifies the required locations of SMA connections, in a typical MSBF, to optimize its seismic performance in terms of maximum inter-story drift (MID), maximum residual inter-story residual drift (MRID), and damage scheme.

在垂直模块连接中使用超弹性形状记忆合金螺栓的模块化钢支撑框架的抗震性能

摘要在模块化结构中，单个模块在运输到现场之前在受控的工业环境中构建。然后将它们水平和垂直连接以形成结构。垂直连接可以通过焊接或螺栓连接堆叠模块的柱子来实现。本研究调查了使用超弹性形状记忆合金 (SMA) 螺栓垂直连接的模块化钢支撑框架 (MSBF) 的抗震性能。该研究还确定了典型 MSBF 中 SMA 连接所需的位置，以根据最大层间漂移 (MID)、最大残余层间残余漂移 (MRID) 和损坏方案优化其抗震性能。
