e present study aims to design a robust adaptive controller employed in the active tuned mass damper (ATMD) system to overcome undesirable vibrations in multistory buildings under seismic excitations. We propose a novel adaptive type-2 neural-fuzzy controller (AT2NF). All system parameters are taken as unknowns. e MLP neural network is used to extr...

Fuzzy logic controller is the most common and versatile control algorithm in the structural motion control. In most cases, the formulation of the fuzzy controller is based on the human knowledge and expert so the membership functions and the rule base are formulated by trials and errors. In recent years, there is an increasing interest to optimize...

Owing to the lack of an analytical research on the evaluation of mode change of web panels in addition to the need for shear design curves of unstiffened plate girder web panels exposed to shear buckling especially at elevated temperatures, the present article considers the mentioned topics. To this end, the web panel shear design relationships men...

In this article, elastic shear buckling and ultimate shear strength of long steel plate girder web panels subjected to pure shear loading are investigated at both ambient and elevated temperatures by the finite element method (FEM). Ninety-six plate girders with compact, non-compact and slender long web panels are numerically analyzed and compared....

In the case of controlling the seismic vibration of a structure, reliance on human knowledge and expert in the formulation of a fuzzy logic controller leads to non-optimal solutions, which makes the use of control devices and algorithm unreasonable. In most cases, the calculated control force for high-rise buildings is very large and the controlled...

In recent years, there is an increasing interest in optimization of structural control algorithms. Fuzzy logic controller is one of the most common and versatile control algorithms that is generally formulated based on the human knowledge and expert. Human knowledge and experience do not yield optimal control responses for a given structure, and tu...

The aim of this work is to develop an approach to optimize the film cooling properties of a gas turbine blade through the optimization of the blade shape and cooling hole location while maintaining the total pressure loss and blade mass flow rate. In this paper, we employ a continuous adjoint method for the design purpose in 2D compressible Navier-...

The aim of this work is to develop an approach to optimize the film cooling properties of a gas turbine blade by minimizing the coolant flow rate while maintaining the blade thermal load, the total pressure loss and blade mass flow rate. In this paper, we employ a continuous adjoint method for the design purpose in 2D compressible Navier-Stokes flo...
