摘　　要：保温砌模现浇钢筋混凝土网格剪力墙结构是一种新型模板保温一体化的住宅建筑结构体系。为将其用于单层农村住宅,提出一种在保证结构安全的前提下可降低工程造价的大砌模低配筋网格墙结构。通过1个试件的拟静力试验,研究大砌模低配筋网格墙的破坏形态、承载能力、变形能力等抗震性能,为工程应用提供试验依据。试验结果表明:大砌模低配筋网格墙的破坏形态为横肢两端出现竖向裂缝或交叉斜裂缝,竖肢水平开裂,两端根部混凝土压碎脱落;试件的承载力满足8度抗震设防要求。The cast-in-situ reinforced concrete grillage shear wall is a new type of structural system,which has the functions of formwork and heat-preservation at the same time.The grillage shear wall is built with heat preservation hollow blocks which are made of expanded polystyrene（EPS） concrete.For applying the wall to rural houses,a system of grillage shear wall with large grid size and low reinforcement ratio has been developed.Pseudo-static test of a specimen was carried out to study the seismic behavior of the grillage shear wall,such as failure mode,load-carrying capacity and deformation capacity.The test results indicate that： vertical and cross oblique cracks appear at the ends of horizontal limbs above the hole,while horizontal cracks occur at the vertical limbs,the concrete crushes at bottom of boundary limbs,the load-carrying capacity can meet the requirements for the one-story residential buildings with seismic fortification intensity 8.
