Risk-based seismic design of buildings using an efficient pushover analysis procedure

A closed form solution for seismic risk assessment incorporating intensity bounds

“…Therefore this parameter has, in general, an impact on the structure of a building, which is obtained according to a risk-based design procedure (e.g. [3]). Consequently, the upper bound of ground-motion intensity should be assessed for the investigated structure's site, and become a standard design parameter.…”

“…However, recently risk-targeting hazard maps have been introduced [1,2], which partly solve the issue of this obsolete practice for the definition of design earthquakes. In a more general case, at least the important structures should be designed utilising the risk-based seismic design procedure [3], which takes into account comprehensive information regarding seismic hazard and ensures a target reliability of structures. Risk-based seismic design is an iterative procedure, which involves seismic performance assessment based on nonlinear analysis methods, seismic risk assessment, which is in the simplest case expressed by the mean annual frequency of limit-state exceedance, and structural adjustment.…”

Risk-Based Design Check for Collapse Safety Using Few Ground Motions

“…[1,2,3]). These procedures are aimed to satisfy the condition that the collapse risk is lower than the target collapse risk, which is assumed acceptable.…”
