Reinforced Concrete Panels Subjected to Uniaxial and Biaxial Tension

摘要

This paper discusses the pre- and post cracking behavior and tensile response of concrete panels subjected to axial tension. The main objective of this investigation is to study the stress-strain relationship of thick reinforced concrete plates, taking into consideration the effect of the steel reinforcement in both directions, as the thick concrete panels are well used in offshore concrete structures and nuclear power plant construction. A theoretical model for predicting the cracking behavior, which includes the crack spacing and width of reinforced concrete panels under axial loading at any given loading stage, is developed. In this theoretical model, the main parameters that influence the cracking behavior of concrete in both directions are considered. The behavior of two-way reinforced concrete plate is analyzed with consideration of the effect of concrete tensile strength, reinforcement ratio, bar diameter and spacing in both longitudinal and transverse directions.
