钢骨混凝土-钢板深梁-混凝土条带组合剪力墙抗震性能试验研究
|
摘要
提出钢骨混凝土-钢板深梁-混凝土条带组合剪力墙,该剪力由钢骨混凝土柱、钢板深梁、混凝土墙体条带3种不同耗能单元组合而成。钢骨混凝土-钢板深梁构成核心结构,混凝土墙体条带与核心结构共同工作,协同抗震耗能。进行了5个不同设计参数的钢骨混凝土-钢板深梁-混凝土条带组合剪力墙试件低周反复荷载试验。试验分2阶段进行:第1阶段,加载至1/50位移角,试件明显屈服损伤;第2阶段,对第1阶段损伤后的试件采用两侧贴焊薄钢板的措施进行修复,并作为5个新的组合剪力墙进行低周反复荷载试验。分析各试件的承载力、刚度、延性、滞回特性和破坏特征。研究表明:钢骨混凝土-钢板深梁-混凝土条带组合剪力墙,变形特征介于带竖缝剪力墙和整体剪力墙之间;在受力过程中,充分发挥了钢骨混凝土、钢板深梁、混凝土条带自身及相互作用消耗地震输入结构能量的作用;钢板深梁参数选择对剪力墙抗震性能影响明显;钢骨混凝土-钢板深梁作为核心结构,实现了延性屈服机制;位移角达1/50损伤修复后,仍具有良好的抗震性能。
A shear wall with SRC columns,steel plate deep beams and concrete strips was proposed.It combines three kinds of energy consumption members which are SRC columns,steel plate deep beams and concrete wall strips.The core structure of SRC columns and steel plate deep beams works together with the concrete strips to consume seismic energy.Five wall specimens with different design parameters were tested under low cyclic loading.The test included two stages.Firstly,the horizontal load was not applied to the specimens until the drift ratio reached 1 /50,when the specimens yielded and were damaged obviously.After that,the thinner steel plates were welded on both sides of the wall so as to strengthen the damaged specimens.The low cyclic loading was then applied to the retrofitted specimens until failure.The load carrying capacity,stiffness,ductility,hysteretic behavior and failure characteristics were discussed.Results show that deformation behavior of shear wall with SRC columns,steel plate deep beams and concrete strips is between that of the shear wall with silts and the overall shear wall.During loading,SRC columns,steel plate deep beams and concrete wall strips work together and consume the seismic energy.The design parameters of steel plate deep beams have an obvious effect on the seismic behavior of the walls.The core structure,SRC columns and steel plate deep beams show good ductile yielding mechanism.The new retrofitted walls still have good seismic behavior by strengthening after damaged at a drift ratio of 1 /50.
