建筑物风压分布随侧风面长度变化的数值研究

ANALYZING NUMERICALLY THE WIND PRESSURE DISTRIBUTION ON BUILDING CHANGE WITH BUILDING LENGTH

用计算机数值模拟风作用下高层建筑周围的紊流流场，从而得到高层建筑外表面上的风压分布沿侧风面长度方向的变化规律，并对风压及风压系数进行数学回归，拟合风压系数分布公式，为建筑结构风荷载和暖通渗风量的计算提供依据。

Using the method of soluting numerically, solute turbulent velocity field around tall building and obtain the wind pressure distribution change with building length. The paper carry on wind pressure and wind pressure cofficient distribution mathematical regression and obtain a series of fitting formulas for calculation wind load of structures and air infiltration of builds.
