Because the active load criterion don ’ t provide the wind load calculate on the complicated shape and circumjacent disturb high - rise buildings , now the primary means to determine the wind load on buildings is wind tunnel test 由于现行荷载规范没有提供复杂外形及周边建筑干扰下的高层建筑风荷载计算,现在确定建筑风荷载的主要手段还是风洞试验。
But the double arch bridges have demerits , for the design lever and the load criterions on the low side then , and the steel is scarce in the structure . when the bridges are loaded heavily , and in heavy traffic for long time , most of them are damage 但是限于当时设计水平和荷载标准偏低,结构钢材用量少,双曲拱桥存在着先天不足,特别是在长期重荷载、大交通量的运营情况下,大部分双曲拱桥都出现了不同程度的病害,许多已成为危桥。
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,得出用于作业棚结构设计的数据,进而按建筑荷载规范和风洞试验数据分别计算出风荷载标准值以及基本风压,通过对两种静力风荷载计算的结果进行比较,可以看出,按规范计算风荷载的结果在结构的整体计算中偏于保守。按照最不利情况计算的设计准则,本论文选用较大的基本风压值按受力面积分配的方法把面荷载转化为线荷载代入midas运算程序中,求得该结构在该静力风荷载作用下的节点最值位移。
On the basis of the design and calculation of such space truss system , this paper has analysed and summed up the experiment dataes of the wind tunnel test and made a deeply research and analysis on this kind of structure which undergoing complicated wind load . compare the wind load values which gained by calculating according to load criterion and the wind tunnel test separately and then analyze and compare the two different results got by static wind load and dynamatic ones separately . at last , analyze the two outcomes through these two different methods which in virtue of finite element program midas 本文在盐田码头闸口的工程设计基础上,分析总结了对该建筑物进行风洞试验的试验数据,并对利用风洞试验数据计算所得风荷载值与按规范计算所得的风荷载值进行了比较,然后借助有限元软件midas对该结构在静力风荷载作用下和动力风荷载作用下的节点位移进行了计算分析和比较。
