Then figure out the wind load in term of the load criterion and the wind tunnel test results separately . by comparing with the two results , we can draw a conclusion that the values which generated by the load criterion are bigger than these ones generated by the other . in order to calculate and design in the worst situation , the paper select the bigger basic wind stress and then turn the area - load into liner - load to receive the displacement of the nodes and the internal force of the cells generated by the static wind load 由此,得出用于作業(yè)棚結(jié)構(gòu)設(shè)計(jì)的數(shù)據(jù),進(jìn)而按建筑荷載規(guī)范和風(fēng)洞試驗(yàn)數(shù)據(jù)分別計(jì)算出風(fēng)荷載標(biāo)準(zhǔn)值以及基本風(fēng)壓,通過對兩種靜力風(fēng)荷載計(jì)算的結(jié)果進(jìn)行比較,可以看出,按規(guī)范計(jì)算風(fēng)荷載的結(jié)果在結(jié)構(gòu)的整體計(jì)算中偏于保守。按照最不利情況計(jì)算的設(shè)計(jì)準(zhǔn)則,本論文選用較大的基本風(fēng)壓值按受力面積分配的方法把面荷載轉(zhuǎn)化為線荷載代入midas運(yùn)算程序中,求得該結(jié)構(gòu)在該靜力風(fēng)荷載作用下的節(jié)點(diǎn)最值位移。
