Abstract

Understanding and predicting the effects of wind loading on a structure is necessary for a safe, effective, and economical engineering design. Wind tunnel techniques are expensive and often provide data that is not sufficiently detailed for the structural engineer. With increasing advances in computational capabilities, it has recently become feasible to investigate these flows using numerical techniques. Of these, one of the most effective approaches to simulate the turbulence observed in natural wind is Large-Eddy Simulation (LES). The application of LES to analyse wind loading, and aeroelastic effects on structures are only a recent venture in the field. This paper reviews the progress made over the last few decades for the analysis of wind flow around slender structures, and the more recent analysis incorporating the effects of freestream turbulence. Firstly, a review of the literature for generating freestream turbulence is carried out, and are assessed based on their flaws and strengths. A number of these are subsequently used for the analysis of surface pressures on an isolated tall model building. Subsequently, a review is made into wind tunnel analysis and LES for the aeroelastic analysis of bridge sections. The recent advances in the understanding of turbulence effects on the aeroestatic responses are summarised. The future of LES and its relationship wind tunnel analysis for wind loading analysis are discussed.
细长结构风荷载大涡模拟研究综述
了解和预测风荷载对结构的影响对安全、有效和经济的工程设计是必要的。风洞技术是昂贵的,通常提供的数据不够详细的结构工程师。随着计算能力的不断进步,使用数值技术研究这些流动最近变得可行。其中,模拟自然风中观测到的湍流最有效的方法之一是大涡模拟(LES)。应用LES来分析风荷载和结构的气动弹性效应只是该领域最近的一个创举。本文综述了近几十年来细长结构周围风流分析的进展,以及最近结合自由流湍流影响的分析。首先,对产生自由流湍流的文献进行了回顾,并根据其缺陷和优势进行了评估。其中一些随后被用于分析孤立的高层模型建筑的表面压力。随后,对风洞分析和LES分析在桥梁截面气动弹性分析中的应用进行了综述。综述了湍流对气动响应影响的最新研究进展。讨论了风洞分析在风荷载分析中的应用前景及其与风洞分析的关系。
