Evaluation of the factors influencing the seismic demand on non-structural elements
Abstract/Contents
- Abstract
- This work focuses on the seismic design of non-structural components, which are elements attached to the floors, roof and walls of a building and are not part of the main structural system. During seismic events, damage to these critically important elements may be extensive, costly and even life threatening. Current building codes that provide design criteria and requirements for non-structural elements follow a simplified prescriptive approach and do not take into account some relevant parameters. Hence, the goal of this work is to examine the factors that influence the seismic demand on acceleration-sensitive non-structural components, evaluate current design criteria and suggest improved requirements with the aim to reduce their level of damage in case of an earthquake. Specifically, the research involves processing and interpretation of strong motion acceleration data, which has been recorded in instrumented buildings in California that have experienced earthquake ground shaking. This work highlights the relevance of building periods and ground motion frequency content in determining the seismic demand on non-structural elements. Furthermore, it shows the role played by the relationship between the natural period of the non-structural component and the vibration modes of the building on the component amplification. Including these factors into the building code design criteria for non-structural elements would better predict the seismic demand on non-structural elements, and it follows that design to the improved demand estimates would reduce earthquake damage to non-structural elements.
