[提要] 對頂部設(shè)有水箱的高層建筑的結(jié)構(gòu)地震響應(yīng)的減震方法及其可行性進行了探討。在常規(guī)動力分析的基礎(chǔ)上，將頂層水箱作為TMD子結(jié)構(gòu)系統(tǒng)，以最大絕對位移及層間位移為主要控制值，研究了改變TMD系統(tǒng)參數(shù)對框架系統(tǒng)的地震響應(yīng)的影響。研究結(jié)果表明，合理配置TMD系統(tǒng)對減小結(jié)構(gòu)地震反應(yīng)是可行的，在土木工程中具有廣泛應(yīng)用前景。
[關(guān)鍵詞] 框架結(jié)構(gòu) 地震反應(yīng) TMD控制 水箱The water tank installed on the top of high - buildings is always adopted in engineermg practice. However. on the viewpoint of earthquake resistant design, it is more inadvisable. The feasibility of reducing seismic response method is explored to this structural system. Based on the routine dynamic analysis, taking the water tank on the top floor as a TMD substructure, the absolute maximum displacement resonse and the drift of storey as the main controlling values, the effect of seismic response of frame structure is discussed by changing the TMD parameters. The results of investigation demonstrat that reasonable disposal TMD system to reduce the earthquake response of frame structure is feasible, effective and economical, and will be widely used in civil engineering in future.
