摘要
高层工业厂房中钢梁和压型钢板-混凝土楼板的组合应用,由于强度高、截面少、经济节约,使楼盖结构整体较柔,存在刚度偏小的问题,从而导致楼盖结构有一定可能出现振动舒适度问题。本文以实际正在施工的高层工业厂房为背景,采用规范中规定的理论计算和现场实测两种方法相互对照,以国内规范中针对自振频率和加速度指标为标准,主要对组合楼盖的一阶竖向自振频率进行了评估,结果显示两种方法获得的频率值在误差允许范围内,同时满足国内规范不小于3Hz的标准。
The combined application of steel beams and profiled steel plates-concrete floor slabs,due to high strength,less cross-section,and economical savings,makes the overall floor structure relatively soft,and there is a problem of low rigidity,which leads to the possibility of vibration in the floor structure.Comfort issues.This paper takes the actual high-rise industrial plant under construction as the background,adopts the two methods of theoretical calculation and field measurement stipulated in the code to compare with each other,and takes the natural vibration frequency and acceleration index in the domestic code as the standard,mainly for the first order of the composite floor.The vertical natural frequency is evaluated,and the results show that the frequency values obtained by the two methods are within the allowable error range,and at the same time meet the domestic standard of not less than 3Hz.
