中文摘要 | 本文針對單柱式與構架式鋼筋混凝土柱提出一套側推分析流程。分析報以力學三大原則為基礎,同時考量軸力、撓曲與剪力等三種應力交互作用的理論模式,作為構材塑性鉸的訂定依據,繼而進行結構側推分析。分析結果並與國家地震工程研究中心和日本土木學會之實驗成果進行比對。本文所提方法可有效掌握平柱式鋼筋混凝土柱構材整體及局部行為,建構合理的非線性側推分析曲線;在構日式鋼筋混礙土柱方面,則提供一考應軸力變化具不失準確性的簡化分析模式,對於鋼筋混凝土結構的耐震性能評估與多目標耐震性能設計將有所助益。本文成果冀能供為學術研與實務設計參之用。 |
英文摘要 | This paper proposes a realistic approach on pushover analyses of reinforced concrete (RC) structures for single column or multiple-column bent. According to theoretical bases and the empirical information, axial force, bending, and shear interactions are considered to derive the properties of plastic hinge corresponding to three distinct failure modes of RC column members. A simplified methodology, considering the variation of axial force of column members during the pushover process of the structure with multiple-column bent, is also recommended for nonlinear analysis of RC buildings with efficiency as well as accuracy. Comparing the experimental results, the proposed approach has been verified in high precision and may be expected to facilitate the pushover analyses of RC structures. |
