摘要:
为了研究新型蜂窝形钢空腹夹层板楼盖的竖向振动舒适度,以自振频率和加速度为双控指标,采用子空间迭代法计算结构基频和各阶振型;然后,采用行走路线法对结构进行时程分析,计算结构在人行荷载作用下的加速度响应.考虑跨高比,上覆混凝土板厚度和上、下肋刚度对结构基频和加速度响应的影响,对结构进行参数化分析.结果表明:蜂窝形钢空腹夹层板基频随着跨高比、上覆混凝土板厚度的增大而减小,随着上、下肋刚度的增大而增大;峰值加速度随着跨高比的增大而增大,随着上覆混凝土板厚度及上、下肋刚度的增大而减小.
Abstract:
In order to study the vibration comfort of the honeycomb shape steel open-web sandwich plate, taking natural frequency and acceleration as the double control index, using the subspace iteration method to calculate the fundamental frequency and every vibration mode. The time history analysis of the structure is carried out by the method of the walking route, and the acceleration response of the structure under the pedestrian load is calculated. Considering the influence of the span-to-depth ratio, the thickness of the overlying concrete slab, the upper and lower rib stiffness on the structural fundamental frequency and acceleration response, the parametric analysis is performed. The results show that the fundamental frequency of the honeycomb decreases with the increase of the span-to-depth ratio and the thickness of the concrete slab, but increases with the increase of the stiffness of the upper and lower ribs. The peak acceleration increases with the increase of the span-to-depth ratio, but decreases with the increase of the thickness of the concrete slab and the upper and lower ribs stiffness.
