dc.description.abstract | 鋼筋混凝土柱構件為結構物中非常重要之構件,在地震力作用下,柱構件需提供良好的軸向與側向承載能力,以及一定程度之變形能力,維持結構物之安全性與使用性。剪力控制之鋼筋混凝土柱構件具有較差之變形能力,易於發生脆性剪力破壞,因此了解剪力破壞控制之柱構件於地震力下之行為是非常重要的研究議題。為了瞭解其行為,學界已大量針對此類構件進行實驗研究,然而基於振動台實驗之限制性與複雜性,大多數實驗研究皆以反覆載重實驗進行。同時,為了進行結構之耐震評估與設計,大量以反覆載重實驗結果為基礎之數值模型已被開發供使用。然而,結構物於真實情況下乃受到具有不同受力機制與作用時間之地震力,而這些反覆載重實驗結果與以反覆載重實驗為基礎之數值模型是否能有效且正確的代表與模擬桿件於真實地震力下之行為,仍有待驗證。本文之研究目的著重於對剪力控制鋼筋混凝土柱桿件之研究,驗證文內試體於反覆載重實驗下之結果與以反覆載重實驗為基礎之數值模型用於代表與模擬真實地震反應之可行性。
本研究比較了剪力控制鋼筋混凝土柱於振動台實驗與於反覆載重實驗下之反應,其比較結果顯示,反覆載重實驗之反應能有效的代表振動台實驗之反應,提供了保守的強度與一致的勁度與位移反應。本研究亦將以反覆載重實驗為基礎之側力位移模型與遲滯模型分別建立於結構分析軟體ETABS與OpenSees內以進行非線性動力歷時分析,並與振動台實驗結果進行比較以驗證其於模擬真實地震反應之可行性。其比較結果顯示,以反覆載重實驗為基礎之強度、勁度、位移與遲滯模型能有效的模擬振動台實驗之反應,提供了保守亦不失精準性之強度、位移與遲滯反應。 | zh_TW |
dc.description.abstract | Reinforced concrete columns are significant members in a structure, providing the structure with axial and lateral resistance with sufficient deformability when subjected to ground motions, ensuring the safety and serviceability of the structure. Shear-dominant reinforced concrete columns are prone to possess brittle failure behavior, and their behavior under dynamic loading conditions are necessary to be clarified. Experiments have been conducted to understand the behavior of shear-dominant reinforced concrete columns, while most of the experiments are based on cyclic loading tests instead of shaking table tests due to the limitation and complexity of the instrumentations and test setups. In the meantime, analytical models have been developed based on the cyclic loading responses for seismic assessment and design of reinforced concrete structures. However, structures are subjected to earthquake forces under practical conditions, and whether these cyclic loading responses and analytical models can represent shaking table responses is yet to be investigated. The objective of this research is to validate the feasibility of the cyclic loading-based responses and cyclic loading-developed analytical models to represent and simulate actual ground motion responses, and to promote the implementation of nonlinear time domain analysis.
The comparison between cyclic loading responses and shaking table responses of RC intermediate-short columns indicates that the cyclic loading responses are capable of representing shaking table responses, providing conservative strength with consistent stiffness and lateral displacement behavior. Column models are developed in structural analysis program ETABS and OpenSees through different modeling concepts based on cyclic loading-developed flexural and shear backbone curves and hysteresis models. Time history analysis is performed on the column models and compared with the shaking table responses. The results indicate that the introduced column models, which consist of cyclic loading-developed analytical strength, stiffness, displacement, and hysteresis behaviors, are capable of simulating shaking table responses, providing both conservative and well simulated force-displacement relationship and hysteresis behavior. | en |
