Interfacial Stress Analysis Of Bonded Plate Reinforced Beam Under The Action Of Temperature And Force

The reinforcement method of bonded plate has been widely used in practical ofreinforcement engineering. However, the effect of this kind of reinforcement depends onits interface bonding effect.so it is important to research for the interfacl stresses of thisreinforcement method. In this paper, the interface stress distribution of the plated beamswhich under the action of temperature and external load has been researched.First of all, based on the theory of elasticity, the analytical solution of bonded platereinforced concrete beams' interfacial stress distribution has been derived. In its derivation,the change of the temperature, even the curvature mismatch and the shear deformations ofbeam and plate are considered. Meanwhile, through an example, the interfacl stressdistribution trends of the plated beam which under the action of the charge of temperatureand external load has been obtained. The characteristic of its distribution trend has beenanalyzed.Secondly, in order to the convenience of study, the analytical solution of bonded platereinforced concrete beams' interfacial stress distribution,when only consider the curvaturemismatch and only consider the shear deformations of beam and plate are both derived.According to this and though a example, the contributions of the temperature change, thecurvature mismatch and the shear deformations of beam and plate to the interfacial stressof plated beamand and are analysed.Furthermore, this study gets the other factors on interfacial stress though changingthe parameters.
