Abstract: Currently, many advanced countries are required to develop a new concept drainage system that meets the increased design standards in order to reduce the economic and casualties caused by deluge floods due to the grown understanding of abrupt climate changes. For example, the existing water drain pump station installed in Korea needs a large amount of land as well as there are many restrictions on the installation. In the case of hybrid system that can be integrated both gate and pump, a new and simplified drainage installations can be provided by integrating pumps, floodgates, and switchgear. Finite Element Analysis (FEA) is a numerical technique method which commonly employed for solving complex problems. It is mainly preferred during development which involves complicated geometry, the corresponding material property changes that cannot be obtained analytically. Until now, the FEA model has mainly been employed using both linear and nonlinear analyses of the structural response due to external loads giving the resulting stresses and deflections. Structural analysis has been made of a hybrid system. The main objective of this paper is to develop a FEA model to apply for the application of the actual situation in the hybrid system which integrated both gate and pump. The software used for the FEA is the general-purpose commercial program, ANSYS. The four cases to study the stresses and deflections in a hybrid system according to bolt diameter with a relatively simple model were selected. The calculated results can be reduced the short engineering time, workforce and cost, and ensured that the same quality is obtained as compared with the accurate model
