黄河淤泥多孔砖砌体中长柱构件受压变形研究

Experiment Study on Mechanics and Deformation Performance of Samples with Yellow River Silt Cellular Bricking Structures Subjected to Compression

按照正交设计方法设计了18个黄河淤泥多孔砖中长柱构件,通过抗压试验,得到了各构件的试验承载力和变形数据.研究了砂浆强度、高厚比和偏心距等因素对构件在竖向荷载作用下承载力和变形性能的影响.结果表明,偏压构件的变形主要受高厚比和偏心距的影响,其截面变形基本符合平截面假定.根据构件内外力平衡的原则,对偏压构件截面变形规律进行了验证,验证结果表明所描述的试件截面变形规律真实可靠.

18 members of slender high column made of Yellow River cellular brick are made based on orthogonal experiment.By the means of compressive test,the limit bearing power and strain data of each member are obtained.Through measurement,the influence of mortar strength,eccentricity and ratio of width-thickness is studied.The result indicates that the major factors of the deformation of eccentric compressive members are eccentricity and ratio of width-thickness and the section deformation of these members can meet...
