摘要

建筑物在服役期间,难免会受到一些偶然荷载,为研究钢管混凝土在横向冲击荷载作用下的破坏模式,对1940mm长、两端固定的空心钢管、普通钢管混凝土、管中管钢管混凝土和内置型钢管混凝土进行冲击模拟,提取了冲击力时程曲线、跨中位移时程曲线和局部变形时程曲线。研究结果发现:在相同冲击荷载作用下,钢管混凝土的抗冲击能力要远好于空心钢管,三种钢管混凝土中管中管钢管混凝土性能最优,空心率对钢管混凝土抗冲击能力影响较大。随着冲击能量的增大,钢管混凝土、管中管钢管混凝土、内置钢管混凝土的冲击力峰值增大,冲击力持续时间也变长。
During the period of their serves.concrete-filled steel structures are inevitable to endure accidental loading.For the study of concrete filled steel tube under lateral impact load failure mode,the paper simulated 1940 mm fixed-end hollow steel tubes,concrete-filled steel tubes,pipe in concrete-filled steel tubes and steel section in concrete-filled steel tubes to extract the impact displacement time history curve,cross and local deformation curve.The results indicate that under the same impact load,concretefilled steel tubes' impact resistant ability is much better than hollow steel tubes.Performance of pipe in concrete-filled steel tubes is best among the specimens.With the increase of impact energy,the peak force and impact duration of the concrete-filled steel tubes,pipe in concrete-filled steel tube,steel section in concrete-filled steel are increased.
