Assessment of the conventional control algorithms and proposing a modified displacement feedback control for performance-based design of structures
(University of Guilan, 2012-01-01)An enhanced displacement feedback structural control procedure is presented for performance-based design in this paper. At first, a comparative study is implemented assessing three most common active control algorithms ...

Buckling and failure characteristics of slender web I-column girders under interactive compression and shear
(University of Guilan, 2012-01-01)Geometric and material nonlinear behavior of slender webs in I-column girders having stocky flanges under the action of combined lateral and axial loads is investigated. Interaction curves corresponding to the application ...

Damage detection of skeletal structures using particle swarm optimizer with passive congregation (PSOPC) algorithm via incomplete modal data
(University of Guilan, 2012-01-01)This paper uses a PSOPC model based non-destructive damage identification procedure using frequency and modal data. The objective function formulation for the minimization problem is based on the frequency changes. The ...

Equilibrium condition nonlinear modeling of a cracked concrete beam using a 2D Galerkin finite volume solver
(University of Guilan, 2012-01-01)A constitutive model based on two–dimensional unstructured Galerkin finite volume method (GFVM) is introduced and applied for analyzing nonlinear behavior of cracked concrete structures in equilibrium condition. The developed ...

Uncertainty in fundamental natural frequency estimation for alluvial deposits
(University of Guilan, 2012-01-01)Seismic waves are filtered as they pass through soil layers, from bedrock to surface. Frequencies and amplitudes of the response wave are affected due to this filtration effect and this will result in different ground ...
