摘要

The paper presents a new formulation for modelling tension in cracked reinforced concrete where the main parameter influencing the response of a member is bond between concrete and reinforcement. The proposed formulation consists of a model for concrete before and after cracking, bond model and a method of predicting crack spacing. The formulation was developed for members subjected to bending and axial loads. It was implemented into a cross-sectional analysis program and was used to analyze specimens which were designed to study the influence of bond on the amount of tension carried by cracked concrete. The comparison between the experiments and the analyses is presented and it shows the same characteristics for both the experimental results and the analyses.
