摘要

应用一种新的湍流脉动流场产生方法（NSRFG）模拟了台北101大楼周围风场的湍流边界条件，采用一种新的大涡模拟的亚格子模型，对台北101大楼进行了全尺寸的数值风洞模拟。得到了台北101大楼周围的风流场及作用于其上的风荷载时程数据。建立了大楼的3维有限元模型，对其进行了摸态分析和基于大涡模拟风荷载时程作用下的瞬态动力分析。计算了风荷载作用下大楼的风致响应。并将计算结果与现场实测以及风洞试验的相应数据进行了对比，结果表明：计算得到的风致响应结果与现场实测以及风洞试验结果吻合较好。本文的数值模拟方法可为高层建筑结构抗风设计提供有效参考。

Abstract

A new turbulent pulsating flow generator was applied to simulate turbulent flow boundary conditions of wind field around Taipei 101 tower.A new large eddy simulation (LES) subgrid model was adopted to conduct full scale numerical wind tunnel simulation for Taipei 101 Tower, and acquire data of wind flow field around the tower and wind load time history ones exerted on it.The 3-D finite element model of Taipei 101 Tower was established, and its modal analysis and transient dynamic analysis under wind load time history obtained with LES were performed.The wind-induced responses of the tower under wind load were computed.The computed results are compared with those of wind tunnel tests and the actual measured ones on site.The results showed that the computed wind-induced response results agree better with the actual measured ones and those of wind tunnel tests; the proposed numerical simulation approach can provide a reference for anti-wind design of super-tall buildings.
