摘要
为获得预应力H型钢混凝土新型组合梁的恢复力模型,对7根跨度为3 800 mm、2根跨度为4 500 mm的预应力型钢混凝土简支梁的骨架曲线进行了仿真分析,探讨了综合配筋指标、预应力度、预应力筋合力点到梁下边缘距离及混凝土轴心抗压强度4个参数对截面单调弯矩-曲率曲线和构件单调荷载-位移曲线的影响,同时考察了综合配筋指标、预应力度对构件截面曲率延性和构件位移延性的影响;最后统计回归出预应力H型钢混凝土组合梁曲率延性和位移延性的计算公式,建立了预应力H型钢混凝土组合梁弯矩-曲率恢复力模型和荷载-位移恢复力模型。结果表明:预应力H型钢混凝土组合梁具有良好的抗震性能,建立的恢复力模型可为该类梁的结构弹塑性动力分析提供参考。
In order to acquire the restoring force models on the new prestressed H-steel reinforced concrete composite beams,the simulation analysis was performed on 7 span 3 800 mm and 2 span 4 500 mm prestressed steel reinforced concrete simple beams.The influences of four factors on the monotone moment-curvature curve of section and the monotone load-displacement curve of member were discussed,which were global reinforcing index,prestressing degree,the distance from the centre of prestressing tendon to the bottom of the beams and axial compressive strength of concrete,and the influences of two factors on curvature ductility of section and displacement ductility of member were investigated,which were the global reinforcing index and prestressing degree.The calculation formulas of the curvature ductility and the displacement ductility of prestressed H-steel reinforced concrete composite beams were given by the statistical regression.Finally,the restoring force models for the moment-curvature and the load-displacement of prestressed H-steel reinforced concrete composite beams were established.The results show that prestressed H-steel reinforced concrete composite beams possess good seismic performance,the restoring force models can provide references for elasto-plastic dynamic analysis on structures of this kind of beams.
