Nonlinear Static Analysis of Shear Wall Sub-assemblages Based on the Uniaxial Spring Model

The Attitude of Variation of Elastic Modules in Single Wall Carbon Nanotubes: Nonlinear Mass-Spring Model

The examination of variation of elastic modules in single wall carbon nanotubes (SWCNTs) is the aim of this paper. Full nonlinear spring-like elements are employed to simulate specific atomic structures in the commercial code ABAQUS. Carbon atoms are attached to each node as a mass point using atomic mass of carbon atoms. The influence of dimensions such as variation of length, diameter, aspect...

Nonlinear modeling of the infill wall based on the brittle cracking model

Abstract: This paper introduces a new numerical method for the analysis of infilled steel frames with hollow clay blocks. This approach is based on the brittle cracking model of ABAQUS. The results of the in-plane calibration analyses obtained with four experimental tests are presented and discussed. The first test was a bare steel frame used as a control specimen. The second was similar to ...

Nonlinear Analysis of Shear Wall Using Finite Element Model

Strain based panel elements for shear wall analysis

The finite element method (FEM) can be applied to practically analyze the tall buildings in which the shear walls are used to resist the lateral loads. Accordingly, a variety of displacement and strain-based as well as frame macro elements have been proposed for analysis of the tall buildings. With respect to application of the lower order plane stress elements, analytical problems may arise wi...

mortality forecasting based on lee-carter model

over the past decades a number of approaches have been applied for forecasting mortality. in 1992, a new method for long-run forecast of the level and age pattern of mortality was published by lee and carter. this method was welcomed by many authors so it was extended through a wider class of generalized, parametric and nonlinear model. this model represents one of the most influential recent d...
