[提要]  通過(guò)大量組合砌體墻片的靜力試驗(yàn)，研究了豎向壓應(yīng)力和約束柱對(duì)組合墻剛度和強(qiáng)度的影響。試驗(yàn)結(jié)果表明，組合墻的側(cè)彎剛度隨豎向壓應(yīng)力的增大而增大，剪切剛度不受豎向壓應(yīng)力影響。豎向壓應(yīng)力對(duì)組合墻的承載能力有較大影響，豎向壓應(yīng)力增大則組合墻的抗剪強(qiáng)度提高。增大約束柱尺寸可以提高組合墻的抗裂強(qiáng)度，增大配筋率將提高組合墻的極限強(qiáng)度。

The static test of some pieces of composite wall which consist of masonry and concrete restraining columns has been carried out to investigate the effects of gravity on stiffness and strength of combined
masonry structures. It is shown that the heavier the pressure acting on the wall is, the bigger the flexu-
ral stiffness of the wall is, but gravity do nothing for the shearing stiffness of the wall. The gravity has
a significant affect on the shearing strength of the wall, the shearing strengthen with the pressure acting on the wall raised. The cracking load of the composite wall can be enhanced by enlarging the area of the restraining columns and the ultimate load of composite wall can be enhanced by enlarging reinforcement ratio of the restraining columns.
Keywords:  composite wall; vertical compress stress; experiment investigation; bending stiffness
