Abstract: The objective of this dissertation is to study qualitatively the proximity effect in a typical Barrage. The study is restricted in scope to representative load cases and response spectrum analysis, considering linear behavior of all materials involves. The Barrage is located partly on RBM (river born material) and partly on rock. Three isolated individual models are analyzed to study the behavior of raft and three composite models are analyzed to study to proximity effect on these individual models. Static analysis of the Barrage has been carried out considering the dead loads (self weight of structure), hydrostatic forces. Free vibration analysis has been carried out to find out the natural frequencies and mode shapes. Seismic analysis of the Barrage has been carried out using the site specific response spectra by giving excitation in transverse direction (across the flow). The study indicates that proximity effects have a significant deviation of results from isolated models both under static and dynamic conditions. From static analysis it can be observed that the stresses reduce in general however, there are stress reversals at some locations. Dynamic analysis indicates presence of larger stresses when proximity is considered in contrast to isolated analysis of individual models/rafts. Results of this study indicate the importance of such studies before arriving at the final design estimates. •
