【摘要】 制作2榀内填材料分别为植物纤维生土基砌块和植物纤维水泥基砌块的1/2比例模型植物纤维复合墙体,进行低周反复加载抗震试验,介绍模型试件的主要破坏过程及受力特点;对比2榀墙体的破坏机制、承载力、滞回特性、抗倒塌能力等抗震性能。试验结果表明,内填植物纤维生土基砌块复合墙体发生"强柱弱板"的剪切型破坏,内填植物纤维水泥基砌块的复合墙体发生"强板弱柱"的弯曲型破坏;内填砌块的抗压强度、抗裂能力和弹性模量等参数的大小是影响植物纤维复合墙体受力性能的主要因素;两种植物纤维复合墙体都具有良好的抗震性能,应用于工程实际是完全可行的。更多还原

【Abstract】 This study is conducted on the main failure process and loading characteristics of two plant fiber composite walls filled with plant fiber soil-based block and plant fiber cement-based block whose ratio is 1∶2 entirely,and a comparative study is conducted on the earthquake-resistant behaviors under low reversed cyclic repetitive loading.Emphasis was put on the evaluation of the failure mechanism,bearing capacity,hysteresis characteristics,ability of anti-collapse.The experiment results show that the shear failure of "strong column and weak plate" occurred in the model of composite wall filled with plant fiber soil-based block,while the bending failure of "strong plate and weak column" occurred in while the model of composite wall filled with plant fiber cement-based block,and the parametric size of compressive strength,anti-crack ability and elastic modulus of infill block are the main factors affecting stressing performance of the composite wall filled with plant fiber.The two types of composite wall filled with plant fiber both demonstrated the excellent earthquake-resistant performance,application of which in the practical engineering is feasible.更多还原
