［摘要］原設(shè)計(jì)為展覽功能的大跨度樓板改造為文藝演出場地后,樓板振動過大，無法滿足舒適安全使用要求。通過對該部位樓板模擬演出激振實(shí)際檢測，并進(jìn)行有限元分析，得出樓板的振動頻率和動荷放大系數(shù)，在舞臺部位采用橡膠隔振器，大幅度降低樓板振動反應(yīng)。經(jīng)過演出現(xiàn)場測試，隔振效果明顯，滿足了安全和舒適使用要求。

Abstract:After the original design of large-pan floor for the use of exhibition changed to entertainment, the vibration of floor is too large and the demand of comfortable and safe use can not be satisfied. Through the actual check of simulated performance on the floor and finite element analysis, the vibration frequency and amplificatory factor of dynamic loads are carried out. By using the rubber vibration isolator on the stage, the vibration response of the floor can be greatly reduced. Through the test of local performance, the effect of vibration isolation is obvious and the demand can be satisfied.
Keywords:vibration of large-span floor; test of floor vibration; stage isolation design; amplification factor of dynamical loads
