補強コンクリート部材の付着割裂性状に関する研究 : その2 横補強のない場合の性状に与える構造因子の影響

摘要

To investigate the correlation between local bond splitting behaviors and average ones in reinforced concrete members, local bond stress (τ_b) versus slippage of reinforcement (s) relationship was proposed in the preceding study (Part 1). This study presents the results of analysis performed to investigate the adaptability of the proposed τ_b-s relationship to average bond behaviors. Analyzed bond splitting strengths show a good correlation with experimental values observed in previous studies. Influence of structural factors, such as bond length, Youngu27s modulus of reinforcement, concrete strength, concrete thickness and specimensu27 scale are also analyzed and discussed in consideration of the experimental results.
