Pile Pillar Abutment Parados Stress Analysis And Its Participation To Cap Beam Bending Analysis

As part of the abutment structure, the abutment parados undertakes the influence of various loads. While the existing criterion for the back wall abutment stress calculation and reinforcement is not clearly defined. The design personnel have often just on the basis of experience to the back wall abutment reinforcement, which lack of theoretical basis and reference for its rational.This article first elaborates the nature and influence of these various loads. Using large finite element program ANSYS, established finite element entity model of pile pillar type abutment (double row pile) in different load by separating entity modeling method; In this model, concrete used SOLID65 unit, reinforced by LINK8 unit.For analyses the stress of bridge abutment structures under the constant and live load,soil pressure alone, and combined effects of both, established the models under three loading modes, at last giving the figures about stress, deformation and cracks. Firstly, analyses the change of stress, deformation and cracks. Secondly, through the analysis of key section, get the abutment parados structures involved in capping beam flexural contribution. Finally, analyses the flexural capacity and the anti-cracking checking by the effects to abutment parados of bridge build board. Ultimately, give beneficial parados design suggestions for design personnel...
