由於近年來阻尼器時常被增加於耐震結構系統中,導致有阻尼偏心的問題存在,以致於一般的地震情況不單有勁度偏心,還會有阻尼偏心的產生。因此本文以人工模擬地震數值解來探討阻尼偏心和勁度偏心互制之周期效應。
首先就White Noise殘值理論解與模擬數值解作比較,探討殘值理論解之正確性;其次以殘值理論解與人工模擬地震解做一比較,探討理論解是否可作為人工模擬地震數值解之偏心互制扭轉研究;最後比較在不同周期下之結構物的扭轉反應。
研究成果如下:
1.以White Noise加速度歷時作為輸入之模擬解,證明了殘值理論解的正確性。
2.以人工模擬地震解與殘值理論解之比較,顯示小勁度偏心與阻尼偏心下,殘值理論解與地震解趨勢近似,可作為一般設計之用。
3. 在大勁度偏心與阻尼偏心下,偏心結構有明顯之周期效應,短周期結構之最大角落位移Ucm值較其他周期結構更大,設計上應予以考量並注意之。
In recent years, damper has been used to mitigate the seismic damage of structures, thus might introducing damping eccentricity to the system in addition to the well known stiffness eccentricity. This study investigates the period effects of damping eccentricity and stiffness eccentricity by investigating the torsional behavior of structure under artificial seismic excitations.
First, the theoretical residue solution was comparing with White Noise simulation results to investigate the accuracy of the theoretical solution. Then, the artificial seismic excitation simulations were used to verify that theoretical solution was similar and could be adopted in engineering design. Finally, the difference in torsional responses of structures with different periods are investigated.
The results are as concluded as following:
1. The theoretical residue solution was verified to be accurate by White Noise simulation.
2. With small stiffness eccentricities and damping eccentricities the results of theoretical solution and artificial simulation earthquake are similar that the theoretical solution could be adopted for design purpose.
3. The period effects of structure with large stiffness eccentricities and damping eccentricities are clearly observed, the maximum corner displacement (Ucm) for structures with shorter period are larger than those with longer periods.
