| Abstract |
Wind-induced internal pressures in partially opened buildings were evaluated by using both a wind tunnel test and an analytical method. The evaluation considers the change of the location and size of the wall openings. The area of the openings was variable between 0.2 % and 3.5 % of the wall area, and the location of the openings was changed into 9 types. The experimental results have been compared with analytical evaluation to investigate the accuracy of a simple analytical approach for the evaluation of wind-induced internal pressures in buildings. Analytically evaluated internal pressure coefficients show a good agreement with experimental results determined by wind tunnel tests. Comparison of internal pressure coefficients with those stipulated in the NBCC Standard indicate that NBCC Standard seems to underestimate wind-induced internal pressures for partially opened buildings. |
