【摘要】：通過風(fēng)洞測力試驗(yàn),研究了不同沙濃度和風(fēng)速條件下風(fēng)沙對低矮建筑整體受力的影響。研究結(jié)果表明:和凈風(fēng)工況相比,風(fēng)沙對低矮建筑整體受力有著較大影響。風(fēng)沙對低矮建筑平均基底剪力系數(shù)有著明顯的增大作用,且沙濃度越大,增大的越明顯。而對于脈動基底剪力系數(shù)的影響,除了與沙濃度有關(guān)之外,還與指示風(fēng)速有關(guān)。當(dāng)風(fēng)速較小時,風(fēng)沙增大了試驗(yàn)房的脈動效應(yīng),而當(dāng)風(fēng)速較大時,風(fēng)沙減小了試驗(yàn)房的脈動效應(yīng)。
[Abstract]:Through wind tunnel force test, the influence of wind and sand on the whole force of low building is studied under the condition of different sand concentration and wind speed. The results show that: compared with the clean wind condition, the wind sand has a great influence on the overall force of the low building. The wind sand has obvious effect on the average base shear coefficient of low buildings, and the bigger the sand concentration is, the more obvious the increase is. The influence of the shear coefficient of pulsating basement is not only related to the concentration of sand, but also to the indicated wind speed. When the wind speed is small, the wind sand increases the pulsation effect of the test room, but when the wind speed is high, the wind sand decreases the pulsation effect of the test room.
