Typological seismic fragility assessment of old railway stations by nonlinear time history analysis

Structure and Infrastructure Engineering, 2020
The homogeneity of standard Italian railway stations in terms of period of construction (second half of the 19th century), architectural and structural features, typical dimensions and morphology (...

Optimum load time history for non‐linear analysis using dynamic relaxation

International Journal for Numerical Methods in Engineering, 1986
AbstractA modification of the dynamic relaxation method is proposed which facilitates static analysis of non‐linear problems. Continuous loading in time is adopted instead of the ordinary step function of time. Inertia and damping forces arising during the loading process are kept at a minimum using an optimum load time history.

Post-earthquake Emergency Response and Recovery Through City-Scale Nonlinear Time-History Analysis

2021
The city-scale nonlinear THA can also be used to evaluate the extent of the emergency response and recovery after an earthquake. This chapter firstly proposes a real-time earthquake damage assessment using recorded ground motions and city-scale nonlinear THA, which can significantly reduce the uncertainties of the ground motion inputs.

Design of Buckling-Restrained Braced Frames Using Nonlinear Time History Analysis and Optimization

Journal of Structural Engineering, 2009
A procedure for the design of buckling-restrained braced frames is presented. The procedure uses nonlinear time history analysis and optimization. Results from this procedure are compared to those from the commonly used equivalent lateral force procedure.

Distributed plasticity approach for time-history analysis of steel frames including nonlinear connections

Journal of Constructional Steel Research, 2014
Abstract This paper presents a displacement-based finite element procedure for second-order spread-of-plasticity analysis of plane steel frames with nonlinear beam-to-column connections under dynamic and seismic loadings. A partially strain-hardening elastic–plastic beam-column element, which directly takes into account geometric nonlinearity ...

Selection of ground motion time histories for nonlinear analysis of earth dams

2015
The selection of natural accelerograms for use in nonlinear analyses of earth dams is still a challenging issue. Customary approaches make essentially use of factors such as earthquake magnitude, distance and site class to obtain spectrum-compatible records with a target spectrum.

ESTIMATION OF BEDROCK EARTHQUAKE MOTION BASED ON NONLINEAR TIME HISTORY ANALYSIS

It is necessary to estimate earthquake motion at the bedrock level from ground surface level records observed near the epicenter in order to elucidate the cause of damage to structures after a large-scale earthquake or to evaluate the design earthquake ground motion.
