Abstract
The project titled “Seismic analysis of Indoor Auditorium” has been taken up with an objective to determine the seismic response and behaviour of an Auditorium constructed in Chennai area. Even though Chennai is considered as least prone to major earthquake, it is expected that a structure would survive major earthquakes without collapse that might occur unexpectedly during the life of the building. It should also be noted that after the Bhuj earthquake, Indian Standard IS: 1893 was revised and Chennai city was upgraded from zone II to zone III which leads to a substantial increase of the design ground motion parameters. Hence, this project presents an exploratory analysis of the seismic performance of multi-storey buildings system built in the specified area with a comparative study of the structures under past major earthquakes. Computer modeling is undertaken using Ansys is a multi-purpose software which enables to run and simulate tests or working conditions. It also helps in determining and improving weak points, computing by 3D simulations in virtual environment.
Highlights
An auditorium is a room built to enable the audience to hear and watch performances at venues such as theatres
An auditorium has an increasing sloped-styled seating, So as to allow the audience at the back of the auditorium to see the stage without any disturbances
Ansys program can be used in all disciplines of engineeringstructural, mechanical, electrical, electromagnetic, electronic, thermal, and fluid
Summary
An auditorium is a room built to enable the audience to hear and watch performances at venues such as theatres. An auditorium has an increasing sloped-styled seating, So as to allow the audience at the back of the auditorium to see the stage without any disturbances. The structural design of an auditorium should be a sloped foundation so as to follow the seating layout. Seismic analysis of an auditorium is done using Ansys and various seismic modes and data are collected. The member with the highest deflection is pointed out and strenghtening methods can be carried out in the project [1,2]
