Seismic design
In seismic design, the objective is not simply to prevent structural collapse but also to ensure that the structure performs in a predictable and controlled manner, even when subjected to strong ground motion. Engineers must ensure that the building goes to controlled yielding mechanism, where selected parts of the structure are allowed to yield, deform, and dissipate energy, without compromising overall stability.
Lateral resisting system
Engineers can decide which type of lateral resisting system to implement. Each system has their specific controlled yielding mechanism which the engineer must ensure that their structure will behave as such.
- Moment Frames (MF): yielding must occur in beams
- Concentric Braced Frames (CBF): yielding must occur in bracings
