Self-resetting steel frame beam-side column joint and construction method thereof
The invention provides a self-resetting steel frame beam-side column joint and a construction method thereof. The self-resetting steel frame beam-side column joint comprises a steel beam, wherein thesteel beam is horizontally arranged on one side of a steel column; a shape memory alloy plate is arranged between a flange of the steel beam and a flange of the steel column, and the shape memory alloy plate is arranged on the outer side of the flange of the steel beam; one end of the shape memory alloy plate is connected with the flange of the steel beam, and the other end of the shape memory alloy plate is connected with the flange of the steel column; and friction energy dissipaters are symmetrically arranged on the two sides of a web of the steel beam, one end of each friction energy dissipater is connected with the steel beam, and the other end of each friction energy dissipater is connected with the flange of the steel column. According to the self-resetting steel frame beam-side column joint and the construction method thereof, the shape memory alloy plate is arranged, and the self-resetting function of the joint is achieved by utilizing the plastic deformation of the shape memory alloy plate; and friction energy dissipation can be achieved between the friction energy dissipaters and the flange and the web of the steel beam, and the friction energy dissipaters and the shapememory alloy plate generate a synergistic effect to jointly absorb seismic energy at the joint, so that the structural ductility and energy dissipation capacity of the steel frame beam-side column joint are effectively improved, and the post-earthquake repair cost of the structure is reduced.
本发明提供了一种自复位钢框架梁‑边柱节点及其施工方法，包括钢梁，钢梁水平设置在钢柱的一侧；钢梁的翼缘与钢柱的翼缘之间设置有形状记忆合金板，且形状记忆合金板设置在钢梁的翼缘外侧；形状记忆合金板的一端与钢梁的翼缘连接，另一端与钢柱的翼缘连接；摩擦耗能器对称设置在钢梁的腹板两侧，摩擦耗能器的一端与钢梁连接，另一端与钢柱的翼缘连接；本发明通过设置形状记忆合金板，利用形状记忆合金板的塑性变形实现节点的自复位功能；通过摩擦耗能器与钢梁的翼缘及腹板之间能够实现摩擦耗能，并与形状记忆合金板产生协同作用，共同吸收节点处的地震能量，有效提高了钢框架梁‑边柱节点的结构延性和耗能能力，降低了结构震后修复成本。
