Description
An industrial building structure made of a 3D RC moment frame has only the perimeter moment frame. It was experiencing severe torsion and non-uniform lateral deformation of the columns. The building has no interior columns and has a heavy gantry girder along one direction.
Problem Statement
A specialist building for the national agency was experiencing an unduly large lateral response. The consultancy organization sought help to mitigate the same.
Outcome of the Research
The use of a ring beam at the gantry level around the entire perimeter of an Industrial Structure (with no interior columns) is beneficial to improve the lateral seismic response of the building. The national agency completed the project and is being used as a critical facility.
