【摘要】：針對大底盤多裙房結(jié)構(gòu)體型復雜龐大、水平及豎向剛度分布不均勻、裙房主塔及隔震層參數(shù)間關系極大影響隔震體系性能及整體隔震效果問題,對主塔、裙樓層質(zhì)量、層剛度及隔震層剛度等不同參數(shù)變化對整體隔震效果影響規(guī)律進行研究。結(jié)果表明,隔震層與主塔層剛度比N≤1/14、裙房樓層數(shù)與主塔層數(shù)比為1/3~1/1.5、群樓相對主塔的層剛度比為0.42~1.1、裙房相對主塔的層質(zhì)量比P≥1.1時主塔減震效果較優(yōu);采用剛性樓板假定所得減震系數(shù)設計上部結(jié)構(gòu)可能會夸大減震效果。大底盤須采用彈性樓板假定。該建議可為此類結(jié)構(gòu)基礎隔震設計提供參考。
[Abstract]:In view of the complex and large structure with large chassis, uneven horizontal and vertical stiffness distribution, and the relationship between the parameters of the main tower and the isolation layer, the performance of the isolation system and the overall isolation effect are greatly affected, and the quality of the main tower and the skirt floor is also discussed. The effects of different parameters, such as floor stiffness and isolation layer stiffness, on the overall isolation effect are studied. The ratio of the stiffness of the isolation layer to the main tower is N 鈮，
