【摘要】 世界上许多国家在 20 世纪二、三十年代已着手墙体材料的改革，逐步推动墙体材料的环保化。我国的政策导向也是禁用实心黏土砖，发展新型墙材产品，速成墙板的出现迎合了时代发展的需要，并成为替代普通黏土砖的首选产品，因为它具有许多在建筑结构应用中的优势，具有广泛的应用前景。本文主要对速成墙板隔孔灌注混凝土时的偏心受压性能进行试验研究，试验对象为 7 组试件，分为三种，分别为隔一孔、隔两孔和隔三孔灌注混凝土，偏心距为 20mm 或 30mm；结合已有的澳大利亚试验结果，对此三种试件的抗压承载能力、破坏特征等作一系列分析与探讨，并利用非线性有限元方法用有限元软件建立力学模型，对其进行力学分析，将分析结果与试验结果对比。研究结果表明，速成墙板隔孔灌注混凝土偏心受压破坏形式为失稳破坏，其抗压承载力满足普通多层房屋建筑的承载力要求，理论分析结果与试验结果符合较好。更多还原

【Abstract】 Many countries have begun the revolution of the wall materials from 1920sto 1930s, and the wall materials were impeled to be environmental protected.The common bricks are also prohibited and new wall materials products areadvocated in our country. The appearance of the rapid wall caters for thedemands of new times, since it has many advantages when applied in buildings.It has amplitude foreground in application. In this paper, the performance of the rapid wall with concrete filled undereccentric axial load will be tested. There are three kind of test specimens withthe total number is seven. They are filled with concrete every one, two or threeholes separately, and the eccentricity is 20mm or 30mm.Some discussions of thecapacity of pressing force and failed characteristics are shown. Besides, byusing nonlinear finite-element method, this article will make a practicalmechanic analysis model and analyse the specimens of the test.The results of theanalysis will contrast with the results of the test. The research results shows that the failure mode of the test specimens isbuckling and the capacity of pressing force of the rapid wall with concrete filledone or more holes(less than three holes) is enough for the tier buildings. Theresults of the theoretical analysis inosculate well with the results of the test.更多还原
