The massive wind tunnel test research indicated that, the wind pressure is extremely obvious along the building crosswise change, assumes the parabola shape distribution, but present "Load code for the design of building structures" ( GBS0009 - 2001 ) windward load average wind pressure value simplification basis of calculation, considers this influence by no means. Base on the wind tunnel test foundation,and the tentative data numerical analysis and the fitting,has obtained the wind pressure coefficient along the building horizontal positi...
