in the conventional design and analysis methods affecting parameters (loads, materials'strength, etc) are not set as probable variables. safety factors in the current codes andstandards are usually obtained on the basis of judgment and experience, which may beimproper or uneconomical. in technical literature, a method based on nonlinear static analysisis suggested to set reliability index on st...

this article is an attempt to explore the subject of divorcee in narrative and visual content of iranian cinema. therefore, by applying constructionist approach in representation theory of stuart hall as the main theoretical framework and using roland barthes’ structural analysis of narrative and john fiske’s semiotic analysis in three levels of reality codes, representation and ideology, ester...

the main cause of structural damage in buildings subjected to seismic actions is lateral drift. in almost all reinforced concrete (rc) structures, whether designed with walls or frames, it is likely to be the code drift limits that control the design drift. the design drift limits and their contribution to damage may be represented indirectly through the material strain limits. the aim of this ...

abstract for seismic design, it is important to estimate the, maximum lateral displacement (inelastic displacement) of the structures due to earthquakes for several reasons. seismic design provisions estimate the maximum roof and storey drifts occurring in major earthquakes by amplifying the roof displacement and drifts of the structures obtained by elastic analysis subjected to seismic design ...

Broader Impacts. The Southern California Earthquake Center (SCEC) conducts a broad program of earthquake system science that seeks to develop a predictive understanding of earthquake processes with a practical mission aimed at providing society with improved understanding of seismic hazards. In partnership with earthquake engineers, SCEC researchers are developing the ability to conduct end-to-...

This paper discusses the analysis of uncertainties in structural analysis of space crafts. Various sources for the discrepancies between prediction and measured response are identified. It is shown that only the effect of scatter of the structural parameters can be studied further by appropriate analysis tools. It is suggested to model uncertainties mathematically within the framework of stocha...

This paper discusses techniques for simulation based optimisation of marine current turbines, and the relative benefits and disadvantages of such methods. Blade Element Momentum codes, Computational Fluid Dynamics and Finite Element analyses, and subsequently the coupling of such techniques, are considered. The relevancy of design, search and optimisation with respect to complex fluid and struc...

A new method for visualizing the behavior of an iterative decoder is presented. This method is applied to regular and irregular low-density parity-check codes. Several types of decoding errors are investigated and suggestions are made for improving the iterative decoder to avoid such errors. Furthermore, structural properties of parity-check matrices that influence the decoding performance are ...

Sub-modeling techniques implemented in commercial finite element codes were reviewed. New sub-modeling applications structural mechanics stress analysis are presented. methods based on displacement and force cut boundary application compared. Advantages disadvantages of these discussed. The case nested sub-models is demonstrated.
