Mechanical Analysis of Water Cellar Structure
Water cellar is an important facility to collect rainfall at the arid and semi-arid areas in China. The numerical simulation was carried out for one type of common cellar structure with concrete cellar wall, bottom floor and brick-arch roof using ABAQUS. Elastoplastic damage constitutive model was adopted to simulate the form and location of cellar cracking under different loads. Simulation results show that the circumferential cracks occures at the out side of the cellar bottom floor and the vertical cracks occures at the top of the cellar wall without water in cellar. In addition, vertical cracks also likely occures at the top of the cellar wall when full of water in cellar. Additional circle beam at the top of the cellar wall can reduce the principal tensile stress of the cellar wall and causing stress redistribution to uniform in the cross-section of cellar wall. Numerical analysis of the different locations of the reinforced concrete wall of water cellar shows that the additional circumferential steel bars at the top of the cellar wall are effective in reducing concrete cellar wall cracks.
