Function-recoverable steel tube recycled concrete frame with replaceable connecting joints
The invention discloses a function-recoverable steel tube recycled concrete frame with replaceable connecting nodes, which comprises two steel tube recycled concrete columns and a steel beam positioned between the two steel tube recycled concrete columns, the bottom of each side surface of each steel tube recycled concrete column is connected with a lug plate, and the bottom of each steel tube recycled concrete column is connected with a foundation platform; the structure further comprises a plurality of weakening type steel plate type dampers, each weakening type steel plate type damper is connected with the foundation platform and the corresponding lug plate through bolts, a plurality of prestressed tendons are connected between the upper portion of each steel pipe recycled concrete column and the end of the corresponding steel beam through bolts in an anchoring mode, and each prestressed tendon is connected with a fishbone block. And an L-shaped connecting plate is connected between the upper part of each steel tube recycled concrete column and the end part of the steel beam. In an earthquake, the weakening type steel plate type dampers, the lug plates and the prestressed tendons can play a role in energy dissipation, bolt connection is mostly adopted in the structure, timely replacement can be carried out when the framework is damaged and fails in the earthquake, the maintenance cost of the framework is effectively reduced, and the service life of the framework is prolonged.
本发明公开了可更换连接节点的功能可恢复钢管再生混凝土框架，包括两个钢管再生混凝土柱和位于两个钢管再生混凝土柱之间的钢梁，钢管再生混凝土柱每个侧面底部连接耳板，每个钢管再生混凝土柱底部连接基础承台，还包括多个削弱型钢板式阻尼器，每个削弱型钢板式阻尼器通过螺栓连接基础承台、耳板，每个钢管再生混凝土柱上部与钢梁端部之间连接通过螺栓锚固连接多个预应力筋，每个预应力筋上连接鱼骨块，每个钢管再生混凝土柱上部与钢梁端部之间还连接L型连接板。在地震中，削弱型钢板式阻尼器、耳板、预应力筋均能起到耗能作用，且结构中多采用螺栓连接，当地震破坏失效时能够进行及时更换，有效降低框架的维护成本提高其使用寿命。
