Design Example of a Building

Example — Seismic Analysis and Design of a Six Storey Building
Problem Statement:
A six storey building for a commercial complex has plan dimensions as shown in Figure 1. The building is located in seismic zone III on a site with medium soil. Design the building for seismic loads as per IS 1893 (Part 1): 2002.

General
1. The example building consists of the main block and a service block connected by expansion joint and is therefore structurally separated (Figure 1). Analysis and design for main block is to be performed. 2 The building will be used for exhibitions, as an art gallery or show room, etc., so that there are no walls inside the building. Only external walls 230 mm thick with 12 mm plaster on both sides are considered. For simplicity in analysis, no balconies are used in the building. 7. Sizes of all columns in upper floors are kept the same; however, for columns up to plinth, sizes are increased. 8. The floor diaphragms are assumed to be rigid. 9. Centre-line dimensions are followed for analysis and design. In practice, it is advisable to consider finite size joint width. 10....
