Anti-seismic tough fabricated concrete frame structure and construction method thereof
The invention provides an anti-seismic tough fabricated concrete frame structure and a construction method thereof. The frame structure comprises prefabricated solid columns, prefabricated superposed beams, T-shaped shear connectors with notches and buckling-restrained energy consumption connecting plates. The prefabricated superposed beam is connected with the prefabricated solid column, and the prefabricated superposed beam comprises a prefabricated superposed middle beam and prefabricated superposed cantilever beams arranged on the two sides of the prefabricated superposed middle beam; the tops of the prefabricated superposed cantilever beam and the prefabricated superposed middle beam are connected through a T-shaped shear connector with a notch, and the notch in the T-shaped shear connector with the notch is located at the zero point of the bending moment of the frame structure under the action of a vertical load; the side faces of the prefabricated laminated cantilever beams and the side faces of the prefabricated laminated middle beams are connected through buckling-restrained energy dissipation connecting plates. A suspension rotating energy dissipation mechanism is adopted, and the method has the advantages of being easy and convenient to construct and install, weak in floor effect, controllable in component damage, sufficient in energy dissipation capacity, efficient in post-earthquake repair, remarkable in economic benefit and the like.
本发明提供一种抗震韧性装配式混凝土框架结构及其施工方法。所述框架结构包括预制实心柱、预制叠合梁、带缺口的T形抗剪连接件和防屈曲耗能连接板；预制叠合梁与预制实心柱连接，预制叠合梁包括预制叠合中间梁和设置在预制叠合中间梁两侧的预制叠合悬臂梁；预制叠合悬臂梁和预制叠合中间梁的顶部由带缺口的T形抗剪连接件连接，带缺口的T形抗剪连接件中的缺口位于框架结构竖向荷载作用下的弯矩零点处；预制叠合悬臂梁和预制叠合中间梁的侧面由防屈曲耗能连接板连接。本发明采用悬挂转动的耗能机制，具有施工安装简便、楼板效应微弱、构件损伤可控、耗能能力充分、震后修复高效和经济效益显著等优点。
