These formulas can provide reference for both the theoretical guide for wind tunnel testing in the near future and choosing the roof cladding local are-averaged coefficient of wind pressure for the designers 這些限值公式為后續(xù)的風(fēng)洞實(shí)驗(yàn)提供了理論指導(dǎo),也可為設(shè)計(jì)人員在選用屋面局部體型系數(shù)時(shí)提供參考。
Finally, with caparisons of that three parapets properties cantilevered parapets has been adopt to the steel structure of light-weight buildings with gabled frames, numerical simulations have been carried out with that buildings, results of simulations show that device can also significantly reduce the area-averaged coefficient of wind pressure and high negative suction peaks on zones susceptible to wind pressure . formula has been proposed about the height of that parapet 最后通過三種女兒墻的性能比較確定對(duì)門式剛架設(shè)置懸挑女兒墻進(jìn)行數(shù)值模擬,結(jié)果同樣表明懸挑女兒墻能明顯地降低門式剛架屋面風(fēng)荷載敏感區(qū)的負(fù)壓峰值及屋面風(fēng)荷載體型系數(shù),并給出了女兒墻高度限值公式。
