摘要
为了研究空间钢构架-型钢混凝土组合柱的偏压受力性能,以偏心距、缀条间距为参数,进行了6根空间钢构架-型钢混凝土组合柱在偏心荷载作用下的静力试验,分析了各试件的破坏形态、承载力以及变形等受力特征。试验结果表明,加载过程中试件截面的平均应变基本满足平截面假定;随着偏心距的增大,试件峰值荷载减小,侧向位移和曲率增大;随着缀条间距的减小,试件峰值荷载增大,且变化幅度不如偏心距改变时显著。
In order to study the eccentric stress behavior of the spatial steel frame concrete column embedded with section steel,the static force test of six spatial steel frame concrete columns embedded with section steel under eccentric load was carried out with the eccentric distance and spacing of the attachment bars as parameters,and the damage morphology,bearing capacity and deformation and other force characteristics of each specimen were analyzed.The test results show that the average strain of the specimen cross-section during loading basically satisfies plane assumption;the peak load of the specimen decreases and the lateral displacement and curvature increase when the eccentricity distance increases;the peak load of the specimen increases when the spacing of the attachment bars decreases,and the change is not as obvious as when the eccentricity distance is changed.
