Discrete-time event history analysis using segmented hazards

Experimental Aging Research, 1991
Event history analysis is a means of explaining variation in the timing of events in individual life histories. This article describes methods for overcoming two difficult problems likely to be encountered in applications of event history analysis to studies of aging and human development.

Event History Analysis in Continuous Time

2001
Event history data are obtained by observing individuals over time, focusing on times of occurrence of certain events and the types of event occurring. A review is given of event history analysis (in continuous time) based on multistate models. Examples of such models include the two-state model for survival data and the competing risks and disability ...

Time History Analysis of Steel Tall Buildings

Advanced Materials Research, 2014
The results of wind tunnel experiments were used to conduct time history analyses of three conventional square cross-section tall buildings with different structural systems. The primary purpose of the study was the direct comparison of the effects of the wind loads on the steel tall buildings.

Time History Seismic Analysis

2013
In the case of design or assessment purposes the seismic capacity of the structural system should be computed for different seismic hazard levels by means of linear or nonlinear time history seismic analyses using a number of properly selected ground motions.

Time-History Analysis of Tibet Gravel Slope

Applied Mechanics and Materials, 2014
In order to obtain the Tibet gravel slope’s response under earthquake, using ABAQUS analysis this kind of slope and get the peak acceleration on the key elements along the slope height. Found that the result can truly gave the max acceleration during earthquake and the acceleration distribution of the slop.

Improved Explicit Method for Time History Analysis

Volume 8: Seismic Engineering, 2007
In this paper, an explicit integration method is presented. This method is shown to have the same numerical characteristics as those of the constant average acceleration method for a linear elastic system. This implies that it is unconditionally stable for linear elastic systems.

Nonlinear inelastic time-history analysis of truss structures

Journal of Constructional Steel Research, 2011
Abstract This paper presents the nonlinear inelastic time-history analysis of truss structures including both geometric and material nonlinearities. The geometric nonlinearity is considered based on an updated Lagrangian formulation, while the material nonlinearity is captured by tracing an empirical stress–strain relationship in the elastoplastic ...
