Finite Element Analysis And Design Of The Pool Structure

Our country in recent years to build a large number of sewage treatment plants, reservoirs, sewage treatment plant essential structures, pools cost accounted for roughly 30% of the total cost of sewage treatment plants, reservoirs directly affect the cost of sewage treatment plants costs. How to ensure the safety of both the pool structure, which in turn cost control within reasonable limits. Research is an important proposition.At present, most of the structural design personnel in accordance with existing norms, by hand calculations and engineering experience to the individual pool members for structural design, the lack of in-depth analysis of the forces of the pool as a whole, the design results may cause the cost of waste or structure chosen not safe. This study analyzed the precise structure of the pool begin, an overall analysis of the pool structure using the finite element numerical simulation in order to obtain a better design proposals.In this study, the design of the relevant provisions of the pool structure summarized; the effects of impact and overall analysis of the pool wall with opening force on the pool design using numerical simulation methods. After analysis, the following conclusions:(1) The impact of negative moment of the wall openings of the vertical supports of the wall is very large, the bending moment is reduced to about one-fifth of the original cave is not open moment, then you can reduce the vertical wall the reinforcement, thus reducing the project cost.(2) Conventional algorithms for security causes, is still very conservative calculation results is too large, through finite element software to calculate the overall pool and results are calculated by plate elements is not much difference, within a reasonable range, the wall of the mutual restraint between the role is very small, so in actual engineering design, in order to increase efficiency, restraint in the form of wall between the fixed constraints can consider the constraints in the form of the wall and the floor between the fixed constraint should also be considered.The relevant conclusions of this study for the future structure of reinforced concrete basin design has some reference.
