STRUCTURE DESIGN OF PUBLIC LIBRARY G+3 CASE STUDY: GASABO DISTRICT, GISOZI SECTOR.

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.
