摘　　要：普通钢板混凝土剪力墙塑性铰区相对薄弱,墙梁连接节点复杂。为此,提出了一种新型可高效建造的部分包裹钢板混凝土剪力墙,并对7片该剪力墙试件进行低周反复荷载试验,研究其破坏形态及抗震性能。结果表明:部分包裹钢板混凝土剪力墙具有良好的极限承载能力和变形性能,试件的破坏形态与剪跨比、内置钢板厚度有关。基于试验结果,建立有限元模型并分析不同参数(剪跨比、内置钢板厚度、PEC暗柱型钢翼缘厚度以及混凝土强度)对剪力墙承载力的影响,给出了提高承载力的工程建议。最后,提出了该类剪力墙的正截面、斜截面承载力计算公式,以期为工程应用提供参考。The plastic hinge zone of traditional steel plate reinforced concrete(SPC)shear walls is relatively weak and the connection nodes of wall-beam are complicated.A new type of partially encased SPC shear wall was proposed,which can be constructed efficiently.Cyclic loading tests were carried out on seven pieces of specimens to study the failure mode and seismic behavior of the specimens.The results showed that the partially encased SPC shear wall has good maximum bearing capacity and deformation performance,and the failure mode of the specimens is related to the shear-to-span ratio and the thickness of the built-in steel plate.Based on the test results,finite element models were established and the effects of different parameters(shear-to-span ratio,thickness of built-in steel plate,thickness of PEC hidden column-section steel flanges and concrete strength)on the bearing capacity of shear wall were analyzed in order to give engineering suggestions to improve the bearing capacity.Finally,the formulae to calculate the bearing capacity of the normal section and inclined section of the shear wall were proposed,which are expected to provide reference for engineering applications.
