Nonstructural components and contents typically represent a significant portion of the total cost of buildings, therefore their damage during earthquakes can lead to large economic losses. Furthermore, damage to nonstructural components may lead to the loss of functionality of the building. For certain kinds of buildings such as hospitals loss of functionality even for short periods of time may be critical. This presentation will summarize recent research aimed at improving the estimation of acceleration demands in buildings. The presentation will put emphasis on understanding the main variables controlling the amplitude and characteristic of seismic demands on building nonstructural components through simplified methods. The accuracy of simplified method is evaluated by comparing floor acceleration demands computed with the simplified method to those computed with response history analyses of detailed finite element models of two generic buildings and those recorded in many instrumented buildings in California. The presentation will include some comment on current code provisions and possible improvements.
In their recent research, Eduardo Miranda and his students have worked on the estimation of economic losses resulting from earthquake ground motions. Their approach involves probabilistic procedures to estimate structural response, physical damage and cost estimation. A special emphasis is being devoted to the development of fragility functions for structural and nonstructural components and to the development of probabilistic cost and downtime estimation functions related to the repair and/or replacement of damaged components.
Before joining the Stanford faculty, Professor Miranda worked as a consulting structural engineer specializing in risk analysis and earthquake engineering. His previous work experience also includes six years of teaching at the graduate school of engineering of the National Autonomous University of Mexico (UNAM) and research at the Mexican Center for Disaster Prevention.
