大跨屋盖的完全三分量等效静力风荷载
Refined three components method for determining equivalent static wind loads of large span roof
摘要
Abstract
For overcoming the defect of traditional three components method and inertial wind load method ,a refined three‐components procedure is proposed to determining ESWLs by stochastic dynamic method .The ESWLs of opening roof are calculated by refined three components method ,it is shown that ,(1) the GLF method can estimate the ESWLs on the equivalent node correctly ,which can not estimate the ESWLs on the non‐equivalent node ,and it is not proper to large span roof .(2)The refined three‐components method is described significantly with physical means ,and is accurate as the same as full modes inertial wind load method in theory ,as well as is more accurate than inertial wind load method with part of modes .(3) The ESWL is under‐estimated about 10% by traditional three components method .T he refined three‐components method can take account into the coupling effect betw een BESWL and RESWL ,w hich is more accurate than traditional three components method ,,w hich can be used successfully in the wind resistance of large span roof .关键词
