Abstract
It is necessary to assume internal pressure coefficient, when deciding the design wind loads for cladding and components based on the wind tunnel test. This paper evaluates the internal pressure coefficients base on the field measurement and wind tunnel test. JMA-Meso Analysis wind velocity is used as the reference wind velocity. And the Analysis wind velocity is comparison with the Doppler Lidar wind velocity. The internal pressure coefficients estimated from the external pressure coefficients measured by the wind tunnel test and the wind force coefficients by the field measurement. The design internal pressure coefficients are appropriate to the net internal pressure.
