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.
