摘要:

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.

Abstract:

According to the orthogonal design method, 18 medium and long column members of the Yellow River silt perforated brick were designed, and the test bearing capacity and deformation data of each component were obtained through the compressive test. The effects of mortar strength, high thickness ratio and eccentricity on the bearing capacity and deformation performance of components under vertical load were studied. The results show that the deformation of the biased member is mainly affected by the high aspect ratio and eccentricity, and the cross-sectional deformation basically conforms to the flat section assumption. According to the principle of internal and external force balance of the component, the section deformation law of the bias member is verified, and the verification results show that the section deformation law of the described specimen is true and reliable.
