在钢结构建筑和桥梁中,为保证主次梁上翼缘对齐,次梁的梁端往往需要切角。在地震、风或温度等作用下,次梁中会出现轴力,从而影响其受力情况。当前关于切角梁在考虑轴力作用下的承载性能仍然缺乏系统研究,因此,本文旨在研究单切角梁在考虑轴力作用下的承载性能。设计并开展了4根足尺单切角梁的静力加载试验,并使用有限元软件对试件进行了深入分析,着重研究了切口区域轴力对承载力的影响。结果表明:所有试件破坏形式均为切口区域腹板局部屈曲破坏;轴向压力会加剧切口区域的应力集中效应,导致切口区域内主压应力增大 ...

海洋工程平台塔架结构中,圆形截面中空双钢管是主要受力构件,其受压性能和耐腐蚀性能工程界十分关注。为研究圆中空夹层不锈钢管水泥砂浆短柱的轴压力学性能,以外不锈钢管壁厚、内碳素钢管直径和是否含夹层水泥砂浆为试验变量,共设计了12根短柱试件。分析各试件的破坏情况、荷载-位移曲线、承载力、变形性能及应变特征,研究不同变量对极限承载力的影响规律。结果表明:试件破坏形式为外钢管端部或中部局部屈曲破坏;随着不锈钢管壁厚的增大,试件的轴压承载力近似呈线性增长;夹层水泥砂浆对试件力学性能影响较大,可有效提高试件承载力 ...
