Understanding the response of structures to earthquake-induced ground motion is critical in Earthquake Engineering. The chapter discusses seismic excitation, dynamic responses of structures, the behavior of single and multi-degree-of-freedom systems, and the principles behind seismic design and response control. Additionally, it highlights non-linear structural responses, retrofitting strategies, and recent advanced developments such as performance-based seismic design and smart structures.
Seismic loads are dynamic and significantly differ from static or wind loads due to their complexity.
The response of structures under earthquake conditions is influenced by their mass, stiffness, damping, and the nature of ground motion.
Modern approaches in seismic design include performance-based metrics, advanced response control strategies, and the use of smart monitoring systems.
Dynamic forces and movements that occur due to earthquakes, impacting the behavior of structures.
Simplified models representing structures capable of exhibiting motion in only one direction.
The total horizontal force transmitted to the base of a structure due to seismic activity.
A static nonlinear analysis method that estimates the structural response under seismic loads through the application of incremental lateral forces.
A design approach that considers various performance objectives to ensure structures can meet specific requirements during seismic events.
