设置芯柱的混凝土小型空心砌块墙体抗震性能研究

Research on Seismic Behavior of Small-sized Hollow Concrete Block Masonry walls with Core Columns

本文通过对设置芯柱的混凝土小型空心砌块墙体的低周反复荷载试验，研究了填芯率对砌块墙体抗震性能的影响。研究表明，设置芯柱能够减轻砌块墙体的剪切摩擦破坏程度，提高开裂荷载与极限荷载，增强变形能力，是改善混凝土小型空心砌块墙体结构抗震性能的一项有效措施。

Through the low-cyclic reverse loading tests on masonry walls made up of small-sized hollow concrete blocks with core columns,this paper studies the effect of infilled ratioof core columns on the seismic behavior of masonry. The results shos that core columns canabate the shear-friction failure of masonry,raise the crack load and ultimate load, and enhance deformation ability.The establishment of core columns in concrete block masonry strocture is an effective method to improve its seismic behavior.
