44. Important Points in Mitigating Effects of Earthquake on Structures

Earthquakes present a critical risk to structures in seismically active regions, necessitating careful design and construction practices to mitigate damage. Key strategies include site selection, architectural considerations, structural configurations, seismic load considerations, material quality, foundation design, separation joints, seismic base isolation, energy dissipation devices, retrofitting methods, and attention to non-structural components. Ensuring compliance with building codes and planning for post-earthquake resilience are crucial to maintaining safety and functionality.
