摘　　要：近几年来,建筑风工程领域的研究取得了重大进展,成果不仅在我国许多标志性超高层建筑和大跨空间结构工程中得到应用,部分已经被吸纳到最新修订的建筑结构荷载规范中。在近地面风特性和基本风速方面,为反映大城市群的建设规模和建筑高度,C,D两类地貌的梯度高度将适当提高,在补充吸收最近大风气象资料的条件下,绘制了新的全国基本风压图;基于大量风洞试验研究,超高层建筑横风向风振、弯扭耦合风振分析及其等效风荷载的计算方法日臻完善和实用,大跨空间结构脉动风荷载非平稳和非高斯特性、等效静力风荷载确定方法的研究取得进展;以计算机数值模拟为主要手段的行人风环境、自然通风及舒适度相关的研究正在逐步展开,是今后风工程研究大有发展前景的方向。Great progresses have been gotten recently in the research of wind engineering for buildings which not only have been applied in some outstanding buildings,but also adopted in new version of Load code for design of building structures.In the aspect of characteristics and reference speed of wind research in near-ground field,the gradient height of wind speed for roughness type C and D shall be increased to reflect the scale and building height appearing in large city groups,and a new wind map has been drawn based on the statistics of renewed climate datum.Depending on a variety of wind tunnel test,the calculation methods for cross-wind and torsion wind-induced dynamic response and wind-resistance design in high-rise buildings have been mature and applicable,the non-stationary characteristics of wind pressure and prediction methods for equivalent static wind load on large-span spatial structures have got progress.Assessment of pedestrian level wind environment,natural ventilation and human comfort related study mainly by means of CFD simulation will be an important direction in wind engineering research.
