［摘要］通過對(duì)4片有上部結(jié)構(gòu)的帶構(gòu)造柱開洞組合墻在上部豎向荷載和樓蓋梁端集中荷載下出平面偏心受壓性能試驗(yàn)，了解了開洞對(duì)柱、圈梁與砌體墻共同工作性能的影響，揭示了開洞對(duì)截面應(yīng)力沿墻體水平和豎向的傳遞與分布規(guī)律以及對(duì)裂縫出現(xiàn)與發(fā)展、構(gòu)件變形與破壞機(jī)理的影響，找出了組合墻出平面偏心受壓性能的影響因素與規(guī)律。為補(bǔ)充和完善現(xiàn)行砌體結(jié)構(gòu)規(guī)范以及組合墻出平面偏心受壓的基本理論與計(jì)算方法提供了試驗(yàn)依據(jù)。

Abstract:Based on the tests of 4 pieces of composite masonry walls with holes which were subjected to vertical load and concentrated loading out-of-plane of the upper floor beam, the influences of holes on the coordination of columns, ring beams and masonry walls under upper floors and concentrated loading out-of-plane were discussed. The transfer and distribution of section stresses in the horizontal and vertical direction of the walls affected by holes, emergence and development of cracks, deformation and failure mechanism of members were revealed. The reasons and rules influencing the behaviors of the composite masonry walls were discovered, which will provide experimental basis for the basic theory and calculation methods of composite masonry walls under out-of-plane and eccentrical compression, in order to fill the blank of current code of masonry structures in those aspects.

Keywords:structural column; composit masonry walls; hole; upper structure; loads; out-of-plane; eccentric compression
