项目摘要
Historical records have shown that damage to properties and loss of lives due to extreme winds have occurred almost every year, and that at current levels, the total economic loss in the US has been estimated in the order of $40 billion per year. Most wind damages occur in low-rise buildings, yet systematic fundamental studies of wind flow over them are very few.In the proposed study, interactions between extreme winds and low-rise building are investigated experimentally on building models in a water-channel facility. Flow visualization techniques are used to gain fundamental insights into complicated wind-structure interactions, in particular, the characteristics of roof flow and base flow around typical low-rise building. The effects of wind directionality and of nearby interfering structures are also investigated. Carefully controlled water flows are produced to resemble the natural wind flow in action.Stress pattern on a building envelope is investigated using the techniques of photoelasticity. Photoelastic coating is applied on a building model, which is then tested in the water channel to reveal the distribution of stresses and their magnitudes during wind-building interaction.The ability to observe simultaneously the nearby flow field and the stress distribution on the building, resulting from fluid loading, represents a significant advance towards understanding the detailed nature of wind-structure interaction. The results of the present investigation are of fundamental importance to developing a sound engineering-science base for the design of low-rise buildings against extreme wind.
历史记录表明,由于极端风造成的财产损失和生命损失几乎每年都有发生,并且在目前的水平上,美国的总经济损失估计为每年400亿美元。 针对低层建筑物的风害问题,本文在水槽实验装置上,对低层建筑物的风场特性进行了实验研究,探讨了极端风场与低层建筑物的相互作用。 流动显示技术被用来获得基本的洞察复杂的风-结构相互作用,特别是典型的低层建筑周围的屋顶流和底部流的特性。 风的方向性和附近的干扰结构的影响也进行了研究。 精心控制的水流模拟自然风的作用。用光弹性技术研究了建筑物围护结构上的应力分布。 在一个建筑物模型上涂上光弹性涂层,然后在水槽中进行测试,以揭示风-建筑物相互作用过程中的应力分布及其大小。同时观察附近流场和建筑物上的应力分布的能力,由流体载荷产生,代表了对了解风-结构相互作用的详细性质的重大进展。 本调查的结果对于为低层建筑的极端风设计开发良好的工程科学基础具有至关重要的意义。
