Seismic retrofit of commercial buildings

After repeated earthquakes in California and around the world, several lessons have been learned and, therefore, design codes have been modified in order to improve the building performance during a major earthquake. The resulting benefit is the reduction of lost life and property. Most buildings constructed prior to the 1960’s lack an adequate system that can resist a major earthquake. There are several techniques of retrofit and upgrade that can significantly enhance the performance of an existing building during a major earthquake event.
