Cyclic Nonlinear Behavior of Pile-Deck Connections Using Structural Software Models

Viscoelastic Modeling of the Recovery Behavior of Cut Pile Carpet After Static Loading: A Comparison Between Linearand Nonlinear Models

Numerical Analysis of Cyclic Behavior of Beam-To-Column Bolted Connections in Steel Frames

This article considers the seismic behavior of beam-to-column joints in steel frames for different bolt arrangements by using of finite element modeling. As the most important beam-to-column joint type, the beam-to-column joints with end-plate is chosen for the analysis. Four different specimens have been analyzed. These models had some differences such as bolt arrangement and the presence or a...

Self-learning simulation method for inverse nonlinear modeling of cyclic behavior of connections

This paper presents an improved self-learning simulation and its application to modeling of ‘cyclic’ behavior of the connections from the results of structural testing. Unlike other inverse modeling approaches such as parameter optimization methods, the proposed method requires no prior knowledge about the behavior and model. It can extract the cyclic connection models by imposing experimental ...

Investigation of the Pile Aging Effect of a Fixed Offshore Platform Located in Persian Gulf using Nonlinear Soil-Pile Interactions

The study about the jacket platforms in the past has revealed that the most of the collapse failures occur due to the lack of strength of the pile foundation. However, when the jacket platforms which have been collapsed due to extreme condition were looked into, it was found that most of them had their foundations intact. These contrasting facts can be explained with the help of the phenomenon ...

INTEGRATING DEXI EVALUATION MODELS INTO DECISION DECK d2 SOFTWARE

DEXi is an educational Multi Criteria Decision Aid (MCDA) computer program aimed at interactive development of qualitative multi-criteria and hierarchical decision models and the evaluation of options. The Decision Desktop software, or d2 for short, is one of the software modules being developed in the Decision Deck project. It is a desktop, client/server application which has integrated severa...
