structural design of a four storied apartment at Nyamagabe district in Gasaka sector…

Abstract

The main purpose of this research was to conduct a technical detail study on the implementation of structural design of a four storied apartment at Nyamagabe district in Gasaka sector to enhance the problem of accommodating and delivering dueling units for all those who work and visit Nyamagabe district. During this research, the analysis of structural elements was made by combining manual analysis, Arch CAD 21 software for providing architectural plans Auto CAD for providing drawing details, Prokon software for analyzing and designing structures and Microsoft word and excel for writing the project report. The study revealed that the building dimensions are 23.05 m by 22.40 m with area of (516.32m2), the minimum requirements for steel bars for slab we provide T10@200mm for Aspro=393mm2, for beams we provide 2T25 with As provided=982 mm2 at (top of the beam in support) and 2T25 with As provided=982 mm2 at (bottom of the beam in middle span) and Provide H8@150mm, For interior columns we Provide4T12 (As=452mm2), 6T16(As=1210 mm2), 6T20 (As=1890 mm2), 6T25 (As=2950 mm2) and Provide H8@125mm(402 mm2) for exterior column we provide 4T20 with reinforcement area of As=1260mm2 and T8@200mm (As=252mm2) for footing we provide H20 at 250 mm C/C (ASP = 1260 mm2) and for stair we provide H12@125mm with As prov=905 mm2/m for main steel and we provide H12@200mm with As prov=566mm2/m for transversal distribution steel. This project gives data about how the design is done and how to know that a structural element is safe against the failure which can caused by loading the structural elements such as: column, beam, slab, stair and foundation.
