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.
