Bangladesh sits in a seismically active region, so earthquake-resistant design is not optional. It is a core responsibility of every structural engineer.
How earthquakes affect buildings
Ground shaking creates lateral forces that a building must resist. Poorly designed structures can suffer severe damage or collapse.
Principles of seismic design
Strong, ductile framing
Buildings are designed to bend without breaking, absorbing energy during shaking.
Regular, balanced layout
Symmetry and continuous load paths help distribute forces evenly.
Proper detailing
Correct reinforcement detailing at joints is essential for ductility.
Following BNBC
The Bangladesh National Building Code sets seismic zones and design requirements that every safe building must follow.
