A Study on Design of G+1 Residential Building

The project aims to apply a systematic and structured approach to meet the functional, aesthetic, and structural requirements of the residential building. By utilizing the ETABS software, the analysis and design process will be streamlined, enabling efficient and accurate calculations of internal forces, reactions, displacements, and other relevant parameters. The software offers a user-friendly graphical interface for model generation and analysis, ensuring the precise evaluation of the building's structural elements. Design a G+1 residential building using the analysing software ETABS is considered crucial in civil engineering. In recent years, there has been a growing emphasis on utilizing computer-aided software and tools for structural analysis, which is highly welcomed by engineers as it alleviates them from the often-lengthy calculations and procedures required when analysing large or com-plex structures using classical methods. However, it is not always necessary for engineers to perform such detailed analyses. Nowadays, high-rise buildings and multistorey buildings are commonplace in metropolitan cities, and these structures often contain numerous joints that are free to move. Manual analysis of such structures can prove to be extremely difficult and time-consuming. Therefore, engineers employ computer-based methods, such as utilizing the modern analysing software ETABS, for more efficient analysis. The objective of this project is to planning, analysis and design of G+1 residential building using the software ETABS. The project focuses on a residential building with specific specifications: -

Plot Size = 130 m², Total built up Area = 100 m²

METHODOLOGY

The methodology for the project involves the analysis and design of a residential building using the software ETABS. The overall process of structural planning and design is followed, considering the functional, aesthetic, and structural requirements of the building.

3.1 Structural Planning: -The first stage of the design process is structural planning, which involves determining the structures, materials, layout of components, analysis methods, and design philosophy. Key aspects such as column positioning, beam placement, slab spanning, staircase layout, and foundation types are considered during this phase. Guidelines and design practices are followed to ensure efficient and effective structural planning.

3.2 Computation of Loads: -Once the structural planning is done, the next step is to compute the loads acting on the building. This includes dead loads (self-weight of the structure), live loads (occupancy loads), wind loads, seismic loads, and any other relevant loads. The loads are determined based on the applicable design codes and standards. Applied loads in structure are: -

• Live load= 2 kN/m²
• Floor finish =1.5 kN/m²

3.3 Method of Analysis: After computing the loads, the chosen software, ETABS is used for structural analysis. ETABS provides a user-friendly graphical interface for model generation and analysis. The software's analysis engine performs calculations for structural analysis, considering the applied loads, structural elements, and their properties. The results are obtained; which include internal forces, reactions, displacements, and other relevant parameters.

3.4 Member Design and Detailing: -Once the structural analysis is completed, member design and detailing are carried out. This involves determining the sizes and reinforcement requirements for structural members such as beams, columns, slabs, and foundations. The design is performed in accordance with the applicable design codes and standards to ensure the safety, serviceability, and durability of the structure.

3.5 Drawing and Preparation of Schedules: -After the member design and detailing, the final drawings and schedules are pre-pared. These include detailed drawings of the structural elements, reinforcement details, and construction specifications. The drawings and schedules provide the necessary information for the construction and implementation of the designed structure. Throughout the entire methodology, the project team consults relevant design codes, standards, and guidelines to ensure compliance and accuracy. Qualified structural engineers or architects may be involved in the process to provide their expertise and ensure the effective planning and design of the building's structural elements. By following this methodology and considering the specific project requirements, the aim is to achieve a well-designed residential building that meets the necessary functional, aesthetic.
