摘要:
随着城市人口的增加,越来越多的超高层建筑在中国各大城市涌现,在其全寿命周期内不可避免的会遭受风甚至地震等多灾害的作用。以上海中心大厦为分析模型,根据其场地条件,采用Benowitez在2015年提出的1种基于随机波的模型方法模拟不同高度处具有空间相关性的脉动风荷载时程。通过对Perform 3D有限元软件建立的上海中心大厦模型进行非线性动力时程分析,研究地震和风耦合作用下对于结构性能的影响,并基于多灾害需求生成结构在地震和风耦合作用下的易损性曲面来研究结构的抗振可靠度。结果表明:结构的响应和易损性随着风速和PGA的增大而显著增大;随着风速的增大结构的响应和易损性均有增大的趋势,但随着地震动的增大,风荷载对结构响应和易损性影响逐步减小。
Abstract:
With the expansion of urban population, more and more super high-rise buildings are springing up in big cities. During their whole life cycle, these buildings will inevitably suffer from multiple hazards such as the wind and even earthquake. Based on the analysis model of Shanghai Tower and its site conditions, this paper adopts the model method based on random wave proposed by Benowitz in 2015 to simulate the fluctuating wind load with spatial correlation at different heights of the structure. Through the nonlinear dynamic time-history analysis of Shanghai Tower model established with Perform 3D, the influence of the combined actions of the seismic and wind loads on the structure was studied. Based on the multi-hazard demand, the vulnerability surface of the structure under the combined actions of seismic and wind loads is generated to study the anti-vibration reliability of the structure. It is illustrated that the structural responses and vulnerability increase gradually with the wind speed and peak ground acceleration (PGA). With the increase of the wind speed, the responses and vulnerability tend to increase, but with the increase of the ground motion, the influence of the wind becomes smaller.
