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5 横補強のある場合の付着割裂強度算定式

摘要

To develop a simple prediction formula of bond splitting strength, local bond stress versus slippage of reinforcement relationship was proposed in the preceding study (Part 4). This research presents the proposal of predicting equation for bond splitting strength with confinement of lateral reinforcement and the results of analysis performed to investigate influence of structural factors, such as bond length, Iateral reinforcement ratio, concrete strength, Youngu27s modulus of lateral reinforcement. The newly developed prediction formula is expressed for two different types, i.e., concrete splitting mode and lateral confinement mode. The predicted bond splitting strengths show a good agreement with experimental results of previous studies.
