severe structural damage, from cracks to total collapse. 
Earthquake-resistant design aims to minimize damage by allowing 
structures to flex and absorb energy.

stress.
Consistent Quality and Predictable Performance
Structural steel is manufactured under controlled conditions, 
ensuring uniformity and high quality. This consistency is 
crucial for engineers to accurately simulate responses under 
various earthquake intensities.
Predictable material behavior allows for reliable and resilient 
structure development.
Ease of Retrofitting Existing Structures
Steel is ideal for retrofitting old buildings to enhance their earthquake resistance. Steel braces, shear walls, or 
external frames can be added to improve lateral stability.
These retrofits are often quicker and more cost-effective than rebuilding from scratch, providing versatile solutions.
