Finite Element Analysis On Flexural Behavior Of RC Beams Strengthened

Concrete pile has developed for over a hundred years of history, concretepipe pile is used for over60years, and the application of prestressed concretepipe pile is more than40years, high-strength prestressed concrete pipe pile is notmore than20years of history. Prestressed concrete pipe pile has good technicalperformance and significant economic benefits etc, so it is more and morewidespread application in the actual project to, and more and more attentionfrom experts, scholars. In the project, we consider the compound pile foundationload, is often a separate analysis of the vertical load and settlement, verticalbearing capacity, or of a pile under lateral load resistance, but the effects of load,vertical load on pile foundation level, there is little research.This topic through determining the failure form pile with ABAQUS finiteelement program analysis, simulation of composite load pile, impact, to thehorizontal bearing capacity of vertical load on the pile at the same time, toobserve the effect of different axial force and pile diameter of the hysteresiscurve, analysis of seismic performance of the pile body.Research shows that: the vertical load exerted on the prestressed concretepipe pile can affect the stiffness, ultimate lateral bearing capacity, and pileaseismic capacity. Prestressed concrete pipe pile diameter of the differentstiffness, ultimate lateral bearing capacity, and pile aseismic ability is alsodifferent.
