Development of an open-source platform for calculating losses from earthquakes [PDF]

, 2012
Risk analysis has a critical role in the reduction of casualties and damages due to earthquakes. Recognition of this relation has led to a rapid rise in demand for accurate, reliable and flexible risk assessment numerical tools and software.

Conditional Spectrum-Based Ground Motion Selection. Part II: Intensity-Based Assessments and Evaluation of Alternative Target Spectra [PDF]

, 2013
In a companion paper, an overview and problem definition was presented for ground motion selection on the basis of the conditional spectrum (CS), to perform risk-based assessments (which estimate the annual rate of exceeding a specified structural ...

Performance of Seismically Isolated and Non‐Isolated Steel‐Framed Buildings: Sensitivity to Amount and Form of Inherent Damping

Earthquake Engineering &Structural Dynamics, EarlyView.
ABSTRACT The amount of inherent damping assumed in nonlinear response history analysis of steel buildings is typically set at 2% or less for the fundamental mode of vibration. However, many studies have shown that actual damping levels vary depending on the building characteristics and soil conditions, and methodologies used in measurements of damping ...

Seismic hazard assessments for El Salvador

Geofísica Internacional, 1996
Se describe la evolución de las normas sísmicas en El Salvador, incluyendo un enfoque probabilística en la norma vigente. Se compara esta última norma con tres trabajos anteriores y se atribuyen las discrepancias a diferencias en cada paso de la estimación y no únicamente en las relaciones de atenuación.

Dual Graph‐Based Bayesian Network Modeling With Rao‐Blackwellization for Seismic Reliability and Complexity Quantification of Network Connectivity

Earthquake Engineering &Structural Dynamics, EarlyView.
ABSTRACT Modern societies depend on various lifeline networks such as transportation, electricity, and gas distribution systems, which are vulnerable to seismic events. Although numerous analytical and simulation‐based methods have been developed for efficient seismic system reliability analysis (SRA), dealing with high‐dimensional events arising from ...

Simplified Estimation of Economic Seismic Risk for Buildings [PDF]

, 2004
A seismic risk assessment is often performed on behalf of a buyer of commercial buildings in seismically active regions. One outcome of the assessment is that a probable maximum loss (PML) is computed.

Investigation on the Calibration of Numerical Models for Cast Steel Replaceable Modular Yielding Links in Steel Eccentrically Braced Frames

Earthquake Engineering &Structural Dynamics, EarlyView.
ABSTRACT A new generation of yielding links, referred to as cast steel replaceable modular yielding links (CMLs), was recently validated through extensive large‐scale testing, to enhance the seismic performance of steel eccentrically braced frames (EBFs). The effective use of CMLs relies on accurately evaluating the seismic response of the EBF systems,

Modeling Nonlinear Cyclic Load–Deformation Response of Corrosion‐Damaged Reinforced Concrete Columns

Earthquake Engineering &Structural Dynamics, EarlyView.
ABSTRACT This study presents a lumped plasticity modeling method for simulating the nonlinear load–deformation response of corroded reinforced concrete (RC) columns with rectangular and circular cross‐sections. The proposed modeling method utilizes an extended column database to enhance the robustness of the database and considers cyclic degradation ...
