摘要
随着现代科技水平和工程技术的不断进步,现代工程的结构更加灵活和创新,比如材料更轻,建筑的跨度更大。但是技术进步的同时也带来了相应的挑战:在外部作用下很容易产生更显著的动态响应,引起楼板共振,导致人们在建筑内的舒适度下降。以某写字楼楼板设计为工程案例,根据楼板结构的自振频率和加速度极限,对节奏振动的大跨度建筑进行理论计算,从而控制楼板振动舒适度,研究结果可为类似建筑设计提供理论参考。
With the continuous progress of modern technology and engineering technology,modern engineering structures are more flexible and innovative,such as lighter materials and longer spans of buildings.However,technological progress also brings corresponding challenges:under the external action,it is easy to produce more significant dynamic response,causing the resonance of the floor,leading to the problem of people's comfort in the building.In this paper,the floor design of an office building is taken as an engineering case.According to the natural vibration frequency and acceleration limit of the floor structure,the theoretical calculation of the long-span building with rhythmic vibration is carried out,so as to control the vibration comfort of the floor and provide theoretical reference for similar building design.
