【摘要】 本文对大开间砖砌体结构采取在砖砌体中增设钢筋混凝土墙中柱和水平条带的加强措施。通过大比例模型试验,探讨大开间约束砖砌体结构的破坏形态,研究其抗剪承载力、变形能力和恢复力特性;论证了在7度区采取此项加强措施后七层大开间结构具有较高的承载力和变形能力,可满足相应的抗震设防要求。更多还原

【Abstract】 This paper presents the measures taken for strengthening a large bay masonry building with additional reinforced concrete columns and horizontal reinforcing strips to form a confined masonry structure. Through a 1/2 scale model test, the failure pattern, shearing capacity, deformation characteristic and the restoring force behavior of this structure are studied. The result shows that the 7 story building built in seismic intensity 7 area has good load bearing capacity and deformation resistant capacity, and the measures taken can meet the requirements of earthquake resistance.更多还原
