augmentation coefficient meaning in English

放尺率

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。
