Abstract The main vulnerability models available in the literature aim to develop damage fragility curves estimate level suffered by a building after seismic event. However, recent earthquakes have highlighted great importance of predicting usability residential buildings, i.e. condition being habitable or occupiable performance can be used as an indicator for allocating economic funding event ...

Pile foundations is a well-studied technique with many applications and its benefits on structures have been widely studied in the literature. In particular, mutual effects of pile flexibility soil deformability may significantly modify seismic behaviour superstructures. order to consider uncertainties that are connected these issues, paper applies probabilistic-based approach fragility curves ...

Seismic resilience is the residual capacity of a damaged system for recovering and sustaining an acceptable level performance as consequence seismic event. Firstly, this paper summarizes current calculation framework using fragility analyses. After that, new metric based on vulnerability analyses developed to calculate resilience. Finally, typical hospital building adopted single then retrofitt...

Abstract The use of ultra-high-performance concrete (UHPC) jackets as a seismic strengthening method for reinforced structures has become increasingly prevalent. Specifically, these are applied to plastic hinge regions the improve overall earthquake resistance. This study evaluates effectiveness UHPC in columns through fragility curves. modeled numerically, accounting material nonlinearity, and...

Due to low stiffness of braces after yielding, the structures with buckling-restrained braces (BRBs) experience high residual drifts during an earthquake, which can be intensified by aftershocks and causes considerable damages to structures. Also, due to poor distribution of stiffness, this problem is exacerbated for irregular structures. Recently, the yielding brace system (YBS) has been intro...

The design of glass structures under dynamic loads still presents a high degree uncertainty. Among others, one the methods to study vulnerability structural systems is based on use fragility curves. This includes seismic evaluation frame as function curves in earthquake engineering. In particular, Cloud method used perform non-linear analysis which provide set data pairs implemented linear-regr...

This paper deals with the seismic vulnerability of monumental unreinforced masonry (URM) towers, fragility which has not yet been sufficiently studied. Thus, present fills this gap by developing models to investigate response URM towers up collapse. On mount Athos, Greece, there exist more than a hundred medieval having served mainly as campaniles or fortifications. Eight representative were se...
