Abstract:
This dissertation presents a detailed study titled "Architectural and Structural Design of a G+3
commercial Building: Case Study of nyarungenge district" The study focuses on a G+3
commercial building at nyabugogo station that measure 207,775m x 158,64m, comprising
essential features like balconies, agency office, restaurant, shops, bus parking, kitchens, bathroom,
offices. Each floor stands at a height of 4 m.
The structural analysis employed fundamental civil engineering principles to meticulously design
key elements, including beams, slabs, columns, foundations, and stairs. Longitudinal beams, with
a depth of 500 mm, width of 200 mm, and a flange width of 907 mm, utilized Ø16 mm
reinforcement bars at both top and bottom. Slabs were diversified into three types (continuous and
discontinuous), each with a 25 cm thickness and reinforced with Ø12 mm bars. Columns
incorporated Ø25 mm bars with Ø8 mm links at 144 mm center to center.
Foundation design adhered to a bearing capacity (Pb= 350 KN/m2), resulting in foundations
measuring 1500*1500*500 mm, reinforced primarily with Ø20 mm bars. Stairs facilitating inter
floor access were crafted with a 265 mm going, 180 mm riser, 200 cm flight height, and a pitch of
32.530. Reinforcement comprised Ø16 mm bars at the bottom and Ø8 mm bars at the top.
This dissertation offers a comprehensive exploration of the structural intricacies involved in
designing a G+3 commercial building. Through meticulous analysis and design, it provides
valuable insights into construction practices, particularly within the unique context of nyarungenge
district.
