由於結構最大位移量是設計與災損評估很重要的依據,因此不少過去文獻致力於發展較有效率的結構物變形量評估方法。國內外文獻目前針對使用高強度鋼筋之鋼筋混凝土桿件在地震力作用下之反應相當有限,因此本研究希望透過兩組接近實尺寸試體之振動台試驗來進一步了解使用高強度鋼筋桿件在地震力作用下之反應。
本研究總共測試兩座鋼筋混凝土構架試體,一座柱主體使用高強度的縱向鋼筋,另一座使用普通強度的縱向鋼筋,試體的設計週期均落在地震反應譜的等加速度段。將兩座試體先做振動台測試,再移至反力牆系統做靜態往復載重測試,並使用過去學者Shimazaki與Sozen (1985)及Lepage (1996)所提出評估結構非線性位移量公式與測試結果比較。根據測試結果顯示,使用高強度鋼筋與普通強度鋼筋試體在未開裂前勁度相似,但一旦試體開裂後高強度鋼筋試體所表現的開裂勁度明顯低於普通強度鋼筋試體,而使用非線性位移量公式評估試體,對於普通強度鋼筋試體而言結果尚可接受,但是對於高強度鋼筋試體而言則明顯低估。
The building deformation is an important basis for design and damage assessment. Therefore, many past literatures concerned about the development of more efficient method to evaluate the structural deformation. Nowadays, national and foreign literatures aim at the limited response of reinforced concrete members using high-strength steel bars under seismic forces. Hence, this research hopes to further understand the use of high-strength steel bars through two sets of shaking table test close to the actual size of the specimen.
In this study, a total of two reinforced concrete frame specimens were tested. One column body used high-strength longitudinal steel bars and the other used ordinary-strength longitudinal steel bars. Both specimen design periods fell in the constant acceleration section of the seismic response spectrum. The procedure was to perform shaking table test, and then continued to do the static reciprocating load test. Finally, evaluate the structure nonlinear displacement using the formula from past researches (Shimazaki and Sozen (1985);Lepage (1996)) and compared it with the experimental results. According to the test results, the stiffness of the high-strength steel bar was similar with the normal-strength steel bar specimen before cracking, but once the specimen cracks, the high-strength steel bar specimen exhibited a significantly lower cracking stiffness than the normal-strength steel bar specimen. Using the nonlinear displacement formula to evaluate the specimen, the result was acceptable for the normal strength steel bar specimen, but it was obviously underestimated for the high strength steel bar specimen.
