Abstract - It is true that bridge are constructed to enable the crossing of river in the monsoon. They are required to be designed so that the minimum obstruction is caused to flow during the monsoon structure. The bridge structure can be designed for a limited storage to serve as water retaining structure to ensure irrigation for a small area as well as to meet the need of drinking water animals and human beings. They also serve as an ideal structure to ensure water recharging of the ground. This project focuses on the analysis and design of various components of Bridge cum Vented Dam. The Bridge cum Vented Dam is analyzed under different Safe Bearing Capacity and results are represented in tables and also the graphs for the better understanding. In the current project the structural components are been analyzed and designed and for the safe design the Bridge cum Vented Dam is designed under ultimate loadings using the method of “Limit State under many load and load combinations using Staad Pro Software. The structure is checked for the stability analysis.The structure is tested for serviceability requirements like limitation on Cracking. The approaches to the Vented Dam on left bank and right bank are through road embankments having width of 7.500m. The road shall be Water Bound Macadam road. The bridge is designed for IRC Class-A loading which is severe as the load will be that of the wt. of gate lifted by gantry. Trajectory bucket type of energy dissipating arrangement is designed at the deep channel. Sluice gate and stop logs gate with crane arrangements is provided for the operation of flow of the water.

Key Words: Bridge cum Vented Dam, Safe Bearing Capacity, and Energy Dissipating arrangements.
