with a mean precipitation rate, much lower than that of the world, iran is among the countries that face severe water challenges. the present study has dealt with the evaluation of hydrochemistry of faryab spring water in hormozgan province, iran. four different composite water samples have been analyzed to detect major anions, cations, total dissolved solids, electrical conductivity, ph, and s...

In this study, the complex behavior of steel encased reinforced concrete (SRC) composite beam–columns in biaxial bending is predicted by multilayer perceptron neural network. For this purpose, the previously proposed nonlinear analysis model, mixed beam-column formulation, is verified with biaxial bending test results. Then a large set of benchmark frames is provided and P-Mx-My triaxial ...

Unique column combinations of a relational database table are sets of columns that contain only unique values. Discovering such combinations is a fundamental research problem and has many different data management and knowledge discovery applications. Existing discovery algorithms are either brute force or have a high memory load and can thus be applied only to small datasets or samples. In thi...

Abstract Effectiveness of providing lime and CFG composite column system on the safety factor embankment constructed consolidating soil is studied at different time intervals during consolidation foundation soil. The effectiveness compared with only or columns. In addition, settlement process also investigated. Embankment, columns are modeled using finite element method. Numbers trial surfaces ...

Abstract A finite element numerical model is used to estimate the force displacement backbone curve of steel moment frame beam-column-joint subassemblies tested at large scale under repeated cyclic loading with different composite deck slab configurations. The configurations included: no-slab; fully isolated slab; two for detailing near region between column flanges; and a full depth reinforced...

The use of fibre-reinforced polymer (FRP) to confine concrete columns improves the strength and ductility by reducing passive lateral confinement pressure. Many numerical analytical formulations have been proposed in literature describe compressive behaviour FRP confined under both monotonic cyclic loads. However, effect a stress/strain level has not well defined because lack well-defined strat...

A series of modeling simulations was performed to evaluate the underlying factors and principles that drive the uncertainty in measured bioaccumulation factors (BAFs) and biota-sediment accumulation factors (BSAFs) for fish, and to determine which sampling designs minimize those uncertainties. Temporal variability of chemical concentrations in the water column, and the metabolism rate and n-oct...
