Mechanical Property Analysis Of Segmental Precast Pier Under Mortise Tenon Joint

Precast assembly technology is becoming more widely used in large-scale building structures,particularly large-span bridges and piers,as China’s economy develops.Cross-section piers are piers at this time in the research.There could be dangers such as shearing,sliding,or being cut.On the basis of previous research,The mechanical properties of segmental precast piles under the action of mortar joints are investigated in this paper,and a segmental precast pile element numerical model is established.It’s finished.The following are the main research findings:(1)The research topics and methods for this paper were determined by reviewing the current state of segmental pier research and theoretical research methods both at home and abroad.(2)ABAQUS finite element software is used to create a finite element model of the entire pier and segmental pier,as well as a numerical simulation of the test conditions to ensure that the software is feasible.(3)Using ABAQUS finite element software,the influence of the mechanical properties of the connecting pier of the specimen is investigated,with the test parameters being the angle of the specimen(TA),the width of the specimen(TW),the constant load axial pressure ratio(CR),and the degree of prestress(MP).The distribution rate of energy-consuming bars and the location of prestressed steel bars(PPR)(ED).(4)A dynamic time history analysis of the plane joint pier,joint segment,and energy dissipation bar joint segment is performed using ABAQUS finite element software.
