The Local Opening Folding Reticulated Shell Structure Surface Wind Pressure Distribution On

The housing opening structure refers to that the open housing doors and windows,orstricken accidental destruction of local area leads to holes. The impact of wind on such astructure is particularly significant, not only to consider the impact of the outer surface ofthe pressure, but also to consider the combined effects of internal and external pressure.This study, camping folding reticulated shell has special nature of structure and using theenvironment,which is quite sensitive to the wind load. Local openings folding reticulatedshell structure of wind-induced response is one of the key issues that need to focus on classstructure wind resistant design.To reveal local openings folding reticulated shell structure inside and outside of windpressure distribution and flow characteristics, based on the basic principles of fluid dynamics,the numerical calculation model was established, the calculation method was discussed, thereasonable calculation parameters were determined. numerical simulation calculationreceived the distribution of local opening structure inside and outside the contour of thesurface pressure coefficient. On this basis,the wind field distribution regularity of the openingstructure housing under different wind speed, wind direction,different hole location and sizeof the main factors and numerical simulation of the error sources were analyzed,and theresults of original structure of the surface pressure distribution law and the internal pressurecoefficient estimate formula were compared. Through internal and external surfaces of thepressure coefficient,the distribution of net shape coefficient was figure ou,and the net shapecoefficient distribution table used in the engineering design was put forward.
