Coupled energy dissipation and shock absorption structure
The invention relates to a coupled energy dissipation and shock absorption structure. The coupled energy dissipation and shock absorption structure comprises a plurality of concrete filled steel tubular columns, at least one steel coupling beam and at least one steel plate shear wall, the steel coupling beams are connected between the two adjacent concrete filled steel tubular columns through steel corbels, and the steel plate shear walls are connected between the two adjacent concrete filled steel tubular columns through fishplates. According to the coupled energy dissipation and shock absorption structure, by reasonably distributing the size, rigidity and bearing capacity of the steel coupling beam and the steel plate shear wall, flexible adjustment and efficient matching of the elastic rigidity and the yield energy dissipation capacity of the structure are achieved, the steel coupling beam and the steel plate shear wall can sequentially generate shear yield under the action of a strong earthquake, and earthquake energy is fully dissipated, the good yield energy dissipation capacity and the good functional recovery after earthquake capacity are achieved, compared with a coupled energy dissipation column only provided with an energy dissipation steel coupling beam, the coupled energy dissipation and shock absorption structure has the advantages that coupled stress of the concrete filled steel tubular column can be fully achieved through the steel coupling beam and the steel plate shear wall under the action of a small earthquake, and the overall rigidity of the structure is remarkably improved.
本发明涉及一种联肢消能减震结构。该联肢消能减震结构包括多个钢管混凝土柱、至少一个钢连梁与至少一个钢板剪力墙；钢连梁通过钢牛腿连接于相邻的两个钢管混凝土柱之间，钢板剪力墙通过鱼尾板连接于相邻的两个钢管混凝土柱之间。该联肢消能减震结构，通过合理分配钢连梁和钢板剪力墙的尺寸、刚度和承载力，实现结构弹性刚度和屈服耗能能力的灵活调整和高效匹配，可以使得钢连梁和钢板剪力墙在强震作用下先后发生剪切屈服、充分耗散地震能量，具有较好的屈服耗能能力和震后功能可恢复能力，在小震作用下，相比仅设置耗能钢连梁的联肢耗能柱，可通过钢连梁和钢板剪力墙充分实现钢管混凝土柱的“联肢”受力，显著提高结构的整体刚度。
