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 ...

Controls on Material and Mesh for Structural Nonlinear Time-History Analysis

Applied Mechanics and Materials, 2014
<strong> </strong>In order to improve the solution of nonlinear time-history analysis for high-rise buildings, the concrete constitutive relation of Chinese code has been modified by using Najar damage theory, and based on the limitation of stable time increment in explicit dynamic analysis, a simplified Rayleigh damping form with tiny ...

NONLINEAR TIME HISTORY ANALYSIS OF A REINFORCED CONCRETE BRIDGE

2021
Earthquakes are one of the greatest natural hazards, which are subject of human research. Bulgaria is a region with medium seismicity and possible seismic impact can lead to damage and destruction both in the building stock and in logistics facilities such as bridges, which would lead to large human and economic losses.

Dual versus amplitude scaling in nonlinear time-history analysis.

2014
In order to estimate the inelastic seismic response of structures modern design codes such as the ASCE7 or Eurocode 8 allow for the use of a family of scaled natural accelerograms in conjunction with nonlinear time-history analysis. In view of this, a number of selection and scaling criteria have been proposed over the years.
