Static Performance Analysis Of Movable Reaction Wall Structure

Reaction wall structure is a kind of experimental facility which provides horizontal reaction and is an important part of structural laboratory.The reaction wall structure can provide horizontal reaction for the experimental structure model or component model,so as to complete the pseudo-static test and pseudo-dynamic test of large scale or full scale model of general structure.With the rapid development of China’s economy,the public’s pursuit of novel and unique architectural modeling is deepening day by day,and more and more new structural forms and new components appear in the public’s vision.Therefore,new requirements and challenges are put forward for the design of reaction wall structure.A new type of movable unbonded prestressed reaction wall structure is proposed in this paper.On the premise of meeting the design requirements and design specifications,the movable unbonded prestressed reaction wall was designed and analyzed,and ABAQUS finite element analysis software was used to conduct nonlinear static analysis and research on the reaction wall.Firstly,the movable reaction wall studied in this paper is theoretically calculated.Through conceptual design,theoretical calculation and check calculation,the relevant calculation formula suitable for movable reaction wall structure is deduced.Secondly,ABAQUS finite element analysis software is used to conduct finite element simulation and research analysis on movable reaction wall structure.Through the finite element calculation results,the force characteristics of movable reaction wall structure are analyzed,and the theoretical calculation results are compared with the finite element simulation results.Finally,the influence of prestressed steel anchorage structure on the bearing capacity of the movable counter wall structure is analyzed by finite element simulation and calculation.Finally,it is concluded that compared with the results of finite element simulation,the calculation formula of movable reaction wall structure is reasonable and can meet the design and use requirements of reaction wall.The design parameters and length of prestressed steel anchorage structure have a certain influence on the bearing capacity of the counterforce pedestal.
