The Design Software Research Which Based On The Finite Element Method Of Reinforced Concrete Pool

Presently, the softwares of tank for structural analysis and design are still fewer. Therefore it is necessary to develop one kind of simple and functional specificity forces analysis software. Considering the friendly openness of ANSYS, this paper developed corresponding internal force analysis program based on ANSYS.The paper got a computing software of reinforced concrete tank internal force, which based on ANSYS. The software can take water, soil and temperature loads into account. The software used simple input interface, inputted tank overview, material parameters, grid size, load, load combinations and so on. Then we got the tank bending moment under various load combinations through the finite element calculation of ANSYS. By comparing calculation results of program and standard shows that:the program software is able to calculate various load combinations and can meet the engineering needs.In addition, influence of the tank adjacent wall thickness on constraints is analyzed. When the Specification for structural design of reinforced concrete water tank of water supply and sewerage engineering calculate the tank wall, it failed to take into account the influence of adjacent tank wall thickness. The paper studied the influence of different adjoining wall thickness and length height ratio on the constraint. To the tank of fix three edges, the top is hinged or elastic fixation, length height ratio greater than2.0or fix three edges, the top is free edge, length height ratio greater than3.0, we can conclude that:1)the calculations of program software is about the standards’, the max deviation is14.86%;2) the change of the ratio of length and height had little effect on constraint;3) following the increasing of the supported tank wall thickness, the constraints strengthened;4) this paper give the max horizontal bending moment coefficient mc at the corner. The software of the paper organized can be used in practical engineering design tank. Besides, the study results of influence of adjacent tank wall on the constraint, makes the bending moment coefficient at the corner more accurate. The above research can provide reference for design of reinforced concrete tank.
