Structural Analysis and Design of a Primary School Building (4-Storey) in Savar

The school buildings are critical pieces of infrastructure in every country. Several aspects, including structural safety, utility, and economic feasibility, must be carefully considered while creating these structures. The goal of this study is to look at the available research on the structural analysis and design of primary school buildings, particularly four-story structures, in Savar Upazila, Dhaka. This project paper presents the analysis and design of a four-story RCC school building at Dhorenda, Savar, Dhaka, for which we have designed the structural components (beam, column, slab, and foundations). Our building has a total area of 7.68 Katha. The site is located in Savar upazila near Dhaka. It is located about 12 meters South-East from the Dhaka-Aricha national highway. And about 100 meters South-East of Nabinagor market. The principal objective of this venture is to develop a 4 story school building to increase school capacity and accommodate more facilities for students. The BNBC Code and ACI 318 is followed during designing this project. Moreover, the alternative floor plans for the project is analyzed with respect of withstanding seismic and wind load according to the geological condition of the site. The project emphasizes the study's two primary components: structural analysis and design. The structural analysis entails applying the Load and Resistance Factor Design (LRFD) approach to evaluate the loads (self-weight, live load owing to occupancy, and wind load) and establishing the size of the structural elements to assure the building's stability. The ETABS software which is a finite element technique (FEM) is used to study and verify the structure under various loads. The design component of the research addresses the selection and size of structural elements (reinforced concrete columns, beams, and slabs). The output of the study is very helpful understand the difficulties of design and construction of a building and given a direction to smooth of the design process.
