1.0 INTRODUCTION
Introduction
The aims and objectives of this assignment is to introduce the basic process of structural design of a two-storey bungalow to us. It allowed us to gain a holistic structural design experience including the basic concepts in structural design, engineering considerations in building structure, quantification of loads and stresses, as well as the estimation of the sizes of structural members. In this assignment, our tasks are to obtain a set of architectural drawings of a two or three-storey bungalow not exceeding 300 sqm which includes ground floor plan. first floor plan and roof plan. Next, we are required to required to carry out structural framing for the bungalow to include the position of columns, beam to beam and beam to columns connections for each level. The house that I have chose is M16 House. It was built in 2017 by NEBR arquitetura in Carpina, Brazil. The total area for the house is 290 square metres. Furthermore, it consists of : 1. One Main Entrance 2. One Garage 3. One Terrace 4. One Living Room 5. Five Bathrooms 6. Three Bedrooms 7. One Kitchen 8. One Balcony 1
