[提要] 對地震作用下高層建筑TLD控制優(yōu)化設(shè)計方法進行了初步探討。分析了TLD系統(tǒng)對高層建筑振型控制的機理。利用數(shù)值迭代法給出了TLD最優(yōu)參數(shù)設(shè)計表格，并分析了振型參與系數(shù)的影響，為TLD設(shè)計提供了參考。給出了地震作用下高層建筑TLD控制設(shè)計步驟和高層建筑TLD地震反應(yīng)控制仿真分析算例。
[關(guān)鍵詞] 地震 高層建筑 TLD系統(tǒng) 優(yōu)化設(shè)計Research is made on the optimum design method for TLD suppressing vibration of highrise buildings subjected to seisnuc excitation. The machanism of TLD system of highrise building vibration mode control is analysed. The design tables about TLD optimum parameters are given by using iteration. Effect of mode factors is considered on TLD optimum parameters. The design steps of TLD -Highrise buildings system subjected to seismic excitation are given. Eventually, a numerical example of TLD system is used in illustration of their application.
