摘要

三角形鋼板消能器在構架中具有優良的消能減震特性，已於釵h研究中被證實。惟因於實際結構物中，消能器的設置均須與建築空間相互配合，故加消能器的整體效果會受到限制；且每次地震的特性均不相同，故加消能器構架的消能減震效果亦會不同。因此本研究之主要目的為針對含三角形鋼板消能器構架進行振動台試驗，測試三角形鋼板消能器應用在構架上對受地震造成的結構反應折減效果。
經試驗證實加裝三角形鋼板消能器之構架對於位移與柱剪力之折減效果良好，並由其遲滯迴圈圖顯示三角形鋼板消能器為優良的韌性消能構件。
預力式建築結構系統具有自我復位能力及殘餘變位很小之特性，在台灣尚未對此類型之結構系統進行模型分析與研究，因此本研究即針對預力式建築結構系統進行反應譜參數分析，藉由參數分析以認識各參數對預力構件行為的影響，期望能作為相關設計參考之用。
分析結果顯示預力構件中之預力鋼鍵及消能裝置之特性將明顯地影響預力構件之整體遲滯消能。另外，利用PISA3D非線性結構分析軟體可對預力構件之遲滯行為準確模擬。

Many studies have verified that TADAS have good performance in seismic engineering. Structure systems must have appropriate space to set up TADAS limits the effect of TADAS. In addition, with different earthquakes which have different characteristics, the degree of the energy dissipation and earthquake alleviation of the frames with energy dissipating devices is varied. The purposes of this study are testing seismic responses of frames with TADAS.

The test results represent that the frames with TADAS have good efficiency in decreasing displacements and shear force of column. And hysteretic loops of TADAS show that TADAS are good ductility members.

Prestressed structure systems have the property of frame recentering and result in small residual displacements after earthquakes. In Taiwan, there haven’t been any researchs on the analytic model for this type of system. Therefore, the study of spectrum parameters for prestressed structure systems will make all understand the effects of those parameters on prestressed member.

The results of analysis show that the characteristics of tendon and energy dissipating device obviously influence energy dissipation of prestressed member. In addition, the hysteretic behavior of prestressed member can be simulated by PISA3D precisely.
