In this research work, an overview of present power sector of Bangladesh has been discussed with some important proposals for getting maximum efficiency in power generation based on the perspective of Bangladesh. Combination of Duel fuel engine system and Combined Cycle Power Plant (CCPP) should be established in every power station for getting higher efficiency. Whereas, power plants have limitation of fuel in Bangladesh, so that the duel fuel system is very effective for every power station. Besides, the micro-grid concept with renewable energy has been proposed for establishing more effective power system in Bangladesh and for rural development. In this research work, various statistics of generation from different types of running power station, their efficiency, power demand, installed capacity, deficiency of power, power plant under construction and the future plan of the govt. in power sector have been discussed. The present billing scenario has been also listed for getting an idea from the customers’ point of view. A short list has been shown of different types of transmission & distribution losses, overall system losses of Bangladesh & besides, few important proposals of minimizing losses are also included in this research work.

R27-140, Bridge decks often overhang past the exterior girders in order to increase the width of the deck while limiting the required, number of longitudinal girders. The overhanging portion of the deck results in unbalanced eccentric loads to the exterior girders, which are generally greatest during construction. These eccentric loads mainly come from the bridge placing and finishing, equipment as well as fresh concrete and other construction live loads that can create rotation of the exterior girders in the, transverse direction. The rotations can also affect both the global and local stability of the girders as well as the bridge. In this, study, the current bracing systems used by the Illinois Department of Transportation (IDOT) were evaluated through field, instrumentation, finite element analysis (FEA), and the use of the Torsional Analysis Exterior Girders (TAEG)) program., Alternative bracing systems were evaluated through an experimental study and FEA. Based on this work, it is recommended that, intermediate cross frames with top and bottom angles in addition to cross-angle sections in the exterior panels be specified to, limit exterior girder rotation during construction. An alternative approach is to place transverse ties and diagonal pipes in the, exterior panels at a spacing to maintain the spacing-to-girder-depth ratio below 3.94.
