    This project is about the structural design and analysis of B+G+4 building considering all the effects the building receives in its service year. Structural design involves proportioning of structural members of the building and providing reinforcement which results economical. In addition to the structural design and analysis, it also consists of cost estimation of the building with the help of preparing take off sheet. In short, the main structural designs included the paper is as follows. The roof is composed of a flat RC roof the design deals with analysis of the external forces that the roof is exposed. Then, we have selected an adequate strength against the applied wind, dead and live loads that they are subjected to. Our buildings floors are all constructed with a solid RC slab. We have designed the slab for serviceability and ultimate limit state. Therefore, we have selected a depth which satisfies deflection requirement and provided flexural and shear reinforcement. The circulation system in our building is facilitated by a u-shaped stair type. It was designed by analyzing the stair for all loads it is subjected to through its service life and provided with adequate reinforcement. The lateral load analysis includes both wind and earthquake. It consists of lateral load analysis which are wind and earthquake load analysis by ETABS 2016 by using several load combinations and also frames were analyzed using ETABS 2016. After generating the analysis result, we designed beams and columns by assuming a preliminary cross section and finally checking with respect to the maximum shear and flexural moments. Finally, we have provided shear and flexural reinforcements. We have also designed a shear wall for wall and also, we have designed isolated footing type is selected for our foundation. The design was made by taking the loads coming from the super structure through columns. Finally, we generated detail drawings for slab reinforcement, beam reinforcement, column reinforcement and footing reinforcement. Throughout the whole process, different software will be used such as: MS – office (word, excel,) Analysis & design software (ETABS 2016)
