It is major, simple structure and wide scope of use on Gravity abutment of plain concrete, But most of the wall of abutment appears irregular cracks, affect the economy and durability of the abutment and bridge seriously. The paper is based on a bridge of Jiang Xi Rui Xun high-speed engineering, analysis the crack mechanism of abutment by using large-scale finite element software ANSYS to establish reinforcement simulation model of top and bottom ring beam. The stress and vertical deflection of the abutment are meet the requirements, it is meaningful for gravity abutment of plain concrete Strengthening in the future.

Ultimate Limit

Based on the assumption of plane section and linear elastic model, CFRP (carbon fibre-reinforced plastics) strengthening reinforced concrete beam stiffness and deflection have been analyzed in this paper. It is has been solved the problem of such beam’s deflection and stiffness problem in the serviceability limit state, that is can’t be properly calculated with present method, although bearing capacity for the ultimate limit state to this kind of beam is main design aspect. This paper’s calculation formula can guide the relevant components of the design and has been verified by the four root concrete beam’s test results.

Beam Strengthening

Carbon‐filled plastic bands are more extensively used for strengthening the permanently exploited curved elements. As a result, the bending rigidity of the element is increased and the crack formation process is changed. Investigation of these problems is carried out basing on the model of laminated material, in which the mechanical properties of separate layers may have discreete different values depending on the external load volume. Practical calculations are made by numerical methods which make it possible to follow up the origin of the crack formation in the concrete, by taking into account its non‐linear deformation character. The work deals with the analysis of the beam strengthening specific character under unloaded and loaded conditions. Testing of the results is performed by using 2 m long reinforced concrete beams strengthened with carbon‐filled plastic bands.
