摘要

摘要: 通过1/2比例双榀联肢生态复合墙体(ECW-6)在水平低周反复荷载作用下的试验研究,分析墙体的破坏形态、破坏过程;研究墙体的承载能力、延性、变形、耗能等抗震性能;针对不同单因素变化对联肢生态复合墙体斜截面受剪承载力的影响,建立墙体的非线性有限元模型进行分析。试验结果及理论分析表明:联肢生态复合墙体与标准墙体相比具有良好的抗震性能。具体表现为,承载能力、变形以及延性均有所提高,并有较好耗能和抗倒塌能力。根据墙体斜截面受剪承载力影响因素分析,提出适用于联肢生态复合墙结构的斜截面受剪承载力计算公式,给出公式的适用范围。能够较好地反映结构的真实受力性能,在实际工程应用中有一定的适用性。

Abstract: By researching on the test of a 1/2-scaled model of the united limb eco-composite wall under lowfrequency cyclic loading, the failure pattern, failure process of the wall were analyzed and the aseismatic capacity ofthe bearing capacity, ductility, deformation and energy dissipation was researched．A non-linear finite element modelof the wall was set up in allusion to the inclined section shear capacity of united limb eco-composite wall, with whichan analysis of different single-factor changes was done．Experimental results and theoretical research show that incontrast with single wall, the united limb eco-composite wall has better seismic performance．The specificperformance is that bearing capacity, deformation and ductility of the wall are increased, and it has a better energydissipation and anti-collapse capacity．According to the analysis of the oblique section bearing capacity factors, it wasput forward the equation of oblique section ultimate bearing capacity of the united limb eco-composite wall, and thescope of application of the formula was also given．The structural performance under load would be better factuallyreflected．It can be applied to practical projects．
