space truss system meaning in Chinese
空间桁架系统
Examples
- Choose two nodes on the edge of the structural to compare the results calculating by the finite element program midas , then we can draw a conclusion that these kinds of space truss systems is sensitive to the libration of the dynamic wind loads . to consider this factor is very necessary in the process of design , we will use the pulsant augmentation coefficient to realize it
比较静力风荷载和动力风荷载作用下的有限元软件的计算结果，选取结构边缘部分的两个节点，对比它们在两种方法计算下的最大位移的计算结果。经过比较可以看出重量轻、频率低、阻尼小的柔性建筑物对风荷载的横向振动是很敏感的，在进行工程设计时应该考虑这种因素，并可采用乘以风振系数等相应方法来加以体现。 - 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。
