Estimation of fragility functions using dynamic structural analysis is an important step in a
number of seismic assessment procedures. This paper discusses the applicability of …

Finite-element dynamic time-history analysis based on stiffness variation is the main
approach to analyzing the seismic fragility of a structure, but using it in practical large-scale …

Cable braces are widely used for seismically upgrading existing frames due to the
significant strength, stiffness, and superior economy. This study investigates the behavior of …

With the increasing emphasis of performance‐based earthquake engineering in the
engineering community, several investigations have been presented outlining simplified …

Reliable collapse assessment of structural systems under earthquake loading requires
analytical models that are able to capture component deterioration in strength and stiffness …

This paper presents the description, calibration and application of relatively simple hysteretic
models that include strength and stiffness deterioration properties, features that are critical …

This report describes a recommended methodology for reliably quantifying building system
performance and response parameters for use in seismic design. The recommended …

The Rayleigh damping model, which is pervasive in nonlinear response history analysis
(RHA) of buildings, is shown to develop 'spurious' damping forces and lead to inaccurate …

This paper describes statistical procedures for developing earthquake damage fragility
functions. Although fragility curves abound in earthquake engineering and risk assessment …

The 'strength'of an earthquake ground motion is often quantified by an Intensity Measure
(IM), such as peak ground acceleration or spectral acceleration at a given period. This IM is …
