Creating Fragility Functions for Performance-Based Earthquake Engineering

EARTHQUAKE ENGINEERING PRACTICE Creating Fragility Functions for Performance-Based Earthquake Engineering

The Applied Technology Council is adapting PEER’s performance-based earthquake engineering methodology to professional practice. The methodology’s damage-analysis stage uses fragility functions to calculate the probability of damage to facility components given the force, deformation, or other engineering demand parameter (EDP) to which each is subjected. This paper introduces a set of procedur...

Fragility of Hydraulic Elevators for Use in Performance-Based Earthquake Engineering

New performance-based earthquake engineering methods developed by the Pacific Earthquake Engineering Research Center, the Applied Technology Council, and others include damage analysis at a highly detailed level, requiring the compilation of fragility functions for a large number of damageable generic structural and nonstructural components. This brief paper presents the development of a fragil...

Modeling Soil Liquefaction Hazards for Performance-Based Earthquake Engineering

Ground motion intensity measures for performance-based earthquake engineering

A critical issue in the probabilistic framework for performance-based earthquake engineering is the choice of ground motion intensity measure(s). In an effort to identify optimum intensity measure(s), a comprehensive parametric statistical study based on 881 earthquake record components was conducted to identify the correlation between (1) seismological variables (SV’s) and traditional ground m...
