Vibration Comfort Analysis of Honeycomb Shape Steel Open-Web Sandwich Plate
摘要
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.关键词
