Webinar details

This study presents an alternative approach to the assessment of earthquake resistance of existing buildings and evaluation of the seismic requirement for a retrofitting process. In order to avoid the assessment of individual components of a building, we propose evaluating it as a whole object using the nonlinear static pushover analysis. In this procedure, the elements’ failure appears in the changes of stiffness at every pushover increment and accumulates until the total failure of a whole structure. Earthquake resistance of the building is quantified as a ratio between the total energy that the existing structure can absorb to the energy at its ideal (upgraded) state that can be estimated using the capacity curves obtained by the pushover analysis. The amount of required retrofitting can be then assessed as the rigidity that needs to be added to obtain the desired resistance.

In this study, we establish the definition for the ideal capacity of an existing structure and corresponding safe displacement limits, a procedure for the derivation of the target capacity curves and the earthquake resistance factor.

Key takeaways from this webinar

  • The stiffening required to achieve the ideal energy absorbing capacity defines the seismic demand.
  • This seismic demand and resistance factor depend on the structural properties of the existing structure and seismic conditions of the building location
