通过对气屏非线性刚度、空气柱非线性阻尼力等的线性化，获得了气屏刚度非线性雨幕墙压力传递的频域解法，基于设计风压下具有常规尺寸及气屏刚度的该类雨幕墙的算例对频域法进行了检验，计算发现：气屏刚度线性化是引起频域求解误差的主要原因，气屏刚度越大或其非线性越弱，频域法精度越高。
通過對氣屏非線性剛度、空氣柱非線性阻尼力等的線性化，穫得瞭氣屏剛度非線性雨幕牆壓力傳遞的頻域解法，基于設計風壓下具有常規呎吋及氣屏剛度的該類雨幕牆的算例對頻域法進行瞭檢驗，計算髮現：氣屏剛度線性化是引起頻域求解誤差的主要原因，氣屏剛度越大或其非線性越弱，頻域法精度越高。

Though the linearization of the air-barrier’s nonlinear stiffness and the air-plug’nonlinear damping force in the rainscreen’opening and etc. ,a frequency-domain analysis method for the pressure equalization of the rainscreen when with a nonlinear air-barrier was derived. Based on the calculation cases of the rainscreen with normal geometry and air-barrier’s stiffness under ordinary wind load,the precision of the method were investicated. It was found that the error of the frequency-domain analysis is mainly arose from the linearization of the nonlinear stiffness,and the bigger the stiffness,or the less the nonlinear,the more precision the frequency-domain analysis.
