为了研究黏土砖再生粗骨料混凝土短肢抗震墙的受力和变形性能,设计了2个黏土砖再生粗骨料混凝土短肢墙试件和1个普通钢筋混凝土短肢墙对比试件,试件的尺寸、配筋和轴压比等参数均相同。采用低周反复的加载方式,测试了各试件的受力与变形性能,并对试件的承载力、刚度、延性、耗能能力和破坏形态进行了对比分析。研究结果表明:在相同的配筋和轴压比下,黏土砖再生粗骨料混凝土短肢抗震墙试件比普通混凝土短肢抗震墙试件的承载力有所降低,延性和耗能能力也有所降低,但降低幅度较小;黏土砖再生粗骨料混凝土短肢抗震墙的承载力和变形性能均能满足结构的抗震要求。
In order to study the force and deformation performance of recycled concrete short-limbed seismic walls with clay brick, two clay-brick recycled coarse concrete short-limb wall specimens and one ordinary reinforced concrete short-limb wall specimens were designed. The size of the pieces, reinforcement and axial pressure ratio and other parameters are the same. The low-cycle repeated loading method was used to test the force and deformation performance of each specimen. The bearing capacity, stiffness, ductility, energy dissipation capacity and failure morphology of the specimens were compared and analyzed. The results show that under the same reinforcement and axial compression ratio, the bearing capacity of the recycled concrete short-leg earthquake wall with clay brick is lower than that of ordinary concrete short-limbed seismic wall. The ductility and energy dissipation capacity But the decrease is small. The bearing capacity and deformation performance of the recycled short-leg earthquake resistant wall with clay brick can meet the seismic requirements of the structure.
