Nonlinear inelastic time-history analysis of truss structures
Journal of Constructional Steel Research, 2011Abstract 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
2021Earthquakes 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.
2014In 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.

Seismic fragility analysis of a buried gas pipeline based on nonlinear time-history analysis
International Journal of Steel Structures, 2016Seismic fragility analysis was performed for API X65, a type of buried gas pipeline that is widely used in Korea. For this purpose, nonlinear time-history analyses were carried out using 15 different analytical models of the pipeline, which represent variations of modeling parameters.

Nonlinear inelastic time-history analysis of three-dimensional semi-rigid steel frames
Journal of Constructional Steel Research, 2014Abstract This paper presents a simple, effective numerical procedure based on the beam–column method by using the based-displacement finite element method for nonlinear inelastic time-history analysis of three-dimensional semi-rigid steel frames. The nonlinear geometry effects are considered by using stability functions and the geometric stiffness ...

Nonlinear Time History Analysis and Optimal Isolator Design for Earthquake Resistant Structures
11th AIAA/ISSMO Multidisciplinary Analysis and Optimization Conference, 2006Seismic isolation and energy dissipation systems are innovative strategies for seismic design, and upgrade or retrofit of bridges. In a retrofit design, base isolation devices can be easily incorporated into existing bridges to replace conventional bearings and to improve the overall structural performance. In this paper, an optimal cost base isolation
