摘 要:为研究不同内填材料对肋格单元抗震性能影响,对3个不同内填材料肋格单元及1个空肋格单元进行了1/2比例模型试验,分析了试件的破坏过程及破坏机理,探讨了不同材料内填砌块肋格单元承载力、变形及耗能能力等抗震性能。试验结果表明:填充加气混凝土砌块试件发生了砌块角部压碎破坏,破坏过程与生态复合墙板的分阶段破坏相对应,是一种合理的破坏形式;加气混凝土砌块与秸秆泥坯砌块对肋格承载力提高较大,但变形能力降低;填充再生EPS轻骨料混凝土砌块试件,砌块较早地退出了工作,对肋格的承载力提高不大;填充秸秆泥坯砌块肋格单元耗能性能较好。研究结果对于生态复合墙体多道抗震防线的优化设计具有一定的参考意义。To study the effects of different filling materials on the aseismic performance of the fib-grid unit, a 1:2 ratio model experiment of three specimens with different filling materials and one specimen unfilled was conducted. The failure process and modes of the specimens were analyzed and the bearing performance, deformation capacity and energy dissipa- tion of different rib - grid units were discussed. The results indicate that the rib-grid unit of aerated concrete block with the crushed comers presents a reasonable failure mode, because the failure develops in stages, which is in agreement with that of the eco-composite wall; the aerated concrete block and straw mud block can improve the capacity of rib-grid unit greatly, but reduce the deformability of the unit simultaneously; the regenerated EPS lightweight aggregate concrete block quits working too early to improve the bearing capacity of the specimen; the rib-grid unit of straw mud block has better energy dissipation performance. The results have certain referential value for the optimization of multi-channel aseismic design for eco-composite walls.
