STRUCTURAL DESIGN AND ARCHITECTURAL DRAWING OF TWO-STORY TECHNICAL VOCATIONAL TRAINING CLASSROOMS AT NGOMA DISTRICT CASE STUDY: KIBUNGO SECTOR

Abstract

This project research was focused on the architectural and structural design of two multistory building of Technical Education Vocation Training school in NGOMA District, case study KIBUNGO Sector due to the lack of modern technical school at KIBUNGO sector. Several methods have been used during the conducted of the project like site observation to check the feasibility study and the appropriate placement of technical school. The main structural members/ elements such as foundation, beam, slab, column and stair and ramp have been designed to provide the safety of the structure. To achieve this, EUROCODE 2-1992 has been used for analysis of different structural elements and soft-wares like Arch CAD to draw architectural plan view, elevations, and sections. For the structural elements analysis only beams are designed by PROKON software for computing beam details and steel reinforcement. The building members like slabs, columns, foundations and stair have been calculated by analytical method by using the basic knowledge in civil engineering. The finding results showed the minimum steel reinforcements in the slab were in two ways direction at the top were ( 7 10/m) and bottom ( 6 8/m). For the beams the minimum steel bars were 5Φ16 at the top and 4Φ16 at bottom. In the column the steel bars were 4ϕ20 for ground floor part, 4ϕ16 for first floor, while for the second floor 4ϕ14. In pad foundation and stairs the steel bars were 6ϕ16mm/m and 6ϕ12 respectively while ground beam corresponded would have 4ϕ16 as minimum steel bars. The obtained results were analyzed in terms of safety. The bill of quantity revealed the amount of the whole building to be of six hundred and twenty seven millions nine hundred and twenty thousand three hundred Rwandan francs. (627,920,300 Rwf). The location of the building was well located at KIBUNGO sector, the load has been calculated and has been compared with bearing capacity and therefore the safety was insured after comparison. Perspective of the building has been established to illustrate different views and fattiness of the structure. Finally, the proposed project has focused on design, geotechnical studies should be conducted before its implementation.
