Estimation of the stress level on a cross section of a reinforced concrete beam via Acoustic emission Intensity Distribution (AID) analysis

Increasing the beam cross section is a kind of traditional and universal strengthening methods of civil structure. The mechanical performance test were studied on the mechanics performance and deformation of four reinforced concrete beams in this study. The results show that increase of the cross section and tensile area at the bottom of the steel could effectively improve the performance of mechanical. The beam crack load, yield load, ultimate load and bending strength are increasing with cross section and mechanical. By simulating the relationship bwteen load and deflection. It is concluded that The finite element simulation of reinforced concrete beam with the reasonable concrete unit and reinforced unit can meet the demand of practical engineering.

Strengthening Method

A large impaired reinforced concrete beam with cracks was strengthened under self-weight action by the externally bonded steel frame composed with bottom steel plate and side hoop steel belts. The normal service loading behaviors of this beam were tested to verify the effectiveness of this strengthening method specified in current Chinese design code. Based on the analyses of test results, it can be concluded that: the deformation of flexural cross section of this beam fitted the assumption of plain cross section, the steel plate could effectively enhance the flexural stiffness and decrease the deflection of this beam, no new cracks appeared under the normal service loads, the cracks at bottom of this beam were more confined by the steel frame than those at web zone. Therefore, other measure should be taken to avoid the opening of web cracks.
