圆中空夹层不锈钢管水泥砂浆短柱轴压性能研究

Jianzhu Gangjiegou Jinzhan
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 ...
