Optimization and influence of GMAW parameters for weld geometrical and mechanical properties using the Taguchi method and variance analysis

Autor: João Paulo Coelho, João Ribeiro, M.T. Braz-César, Émillyn Ferreira Trevisani Olivio, Arthur Casarini

Gas metal arc welding is one of the arc fusion processes that is widely used in industry due to its high efficiency. The correct selection of the input parameters has direct influence on the weld quality and, with the control of those parameters, it

Development of a braine emotional learning based controller for application to vibration control of a building structure under seismic excitation

Autor: João Paulo Coelho, Rui Barros, José Gonçalves, M.T. Braz-César

In this paper, a numerical simulation of a semi-active neuroemotional based control system for vibration reduction of a 3-story framed building structure under seismic excitation is presented. The Brain Emotional Learning Based Intelligent Controller

Numerical simulation of torsional response control of a plan-eccentric mass distribution building by using magnetorheological dampers

Autor: Pedro Folhento, M.T. Braz-César, Rui Barros

Wind and earthquake loads can cause coupled lateral-torsional deformations in building structures due to stiffness and/or mass eccentricities. Simple and regular structural configurations are usually recommended in designing seismic resistant systems

Fuzzy controller optimization using a genetic algorithm for non-collocated semi-active MR based control of a three-DOF framed struture

Autor: M.T. Braz-César, Rui Barros, Pedro Folhento

This paper aims to explore the usefulness of a simple genetic algorithm (GA) optimized Fuzzy Logic Controller (FLC) to reduce the response of a three-DOF framed structure equipped with a MagnetoRheological (MR) damper. These actuators can be controll

Study of structural response due to earthquake excitations: a hardware experimental setup approach

Autor: M.T. Braz-César, Miguel Paula, Rui Barros, José Gonçalves

In this paper it is described a hardware experimental setup applied to study the response of structures due to an earthquake excitation. The described hardware experimental setup was applied in the performance and effectiveness evaluation of passive

Although building structures can be perceived as a combination of primary frames in two orthogonal directions, they are three-dimensional systems that usually present a very complex dynamic behavior due to irregular geometric configurations, in parti
