  • 本文旨在針對單自由度梁柱結構及雙自由度梁柱結構,在特定地震力作用下,於未加阻尼器及加阻尼器時各種結構型式下,利用電腦軟體求出地震歷時位移及地震歷時加速度圖。
    吾人可在歷時分析過程中,將時間分段截取反應值,並針對預設之反應允許值求取破壞機率(超越機率),可知不論以位移或加速度作為破壞機率衡量,結構破壞機率均與設定允許破壞標準值存在相對遞減關係。由本文分析單、雙自由度結構,適當加裝液流阻尼器後,不論在結構位移及加速度皆可有效降低破壞機率,達到耐震補強之功能。

    This research mainly aims at exploring the aseismic ability of the beam-column structure refitted by the fluid damper.
    Two beam-column structural cases are employed in the numerical simulation of this paper .The first one is the case with a single degree of freedom, the other one is two degrees of freedom. The acceleration data of El Centro earthquake is given as the excitation force. The failure probability is calculated according to the failure value self-defined. In terms of the results of the numerical analysis, it can draw a conclusion that displacement and acceleration failure probability can be reduced effectively by the way of a fluid damper strengthening.
