Abstract:
This research project was conducted for the purpose of proving architectural plans and structural
details of a four-story Public Library building in Gasabo district, Gisozi Sector. To achieve
efficiently this project’s goal, some methods have been used like ArchCAD for architectural
drawings different elevations, sections, perspectives and structural design for involve the size of
different component of structural members slabs, columns, foundations and stair, AUTODESK
ROBOT, have been used for the design of beam, and reinforcement Google earth have been
used for well locating the study area so used by Long wall-short wall method for getting the cost
of the project in this method, the wall along the length of room is considered to be long wall
while the wall perpendicular to long wall is said to be short wall. The results showed that
architectural design of building accommodates 100 person each floor have 25 person and
structural design of this project shown that the design steel reinforcement to be arrangement in
slab were 5 bars of 10mm of diameter per meter 5Φ10/m at the top and 5Φ10/m at the bottom
while for beam the designed steel reinforcements were 4Φ16 at the top and 4Φ14 at bottom. And
for column the designed steel reinforcement were 6Φ25for ground floor part of the column and
6Φ25 for first 4ф16 for and third floor part of the column for foundation the designed steel
reinforcement were 5Φ14/m while for stair the designed steel reinforcement were 6Φ10/m
distribution reinforcements the safety of the building have been well insured by comparing the
load from the super structure. The cost of construction of proposed building was estimated
(750,500,000 Rwf). The execution of this project would stimulate proper land use; solve the
problem of current public library operates only during regular working hours.
