Simplified Estimation Method of Plastic Energy Dissipation for MDOF Systems Using Force Analogy Method

open access: yesBuildings, 2023
Plastic energy dissipation is a key factor in the response of inelastic structures subjected to seismic input, and is often regarded as a primary source of structural damage due to the inelastic deformation of structural components. Accurately predicting

SIXTH DEGREE OF FREEDOM

open access: yesInternational Journal for Computational Civil and Structural Engineering, 2020
The article describes new types of finite elements that allow you to take into account all six degrees of freedom of the shell. In order to compose the finite elements, the Allman functional with a rotational degree of freedom is used.

A new two-degree of freedom combined PID controller for automatic generation control of a wind integrated interconnected power system

open access: yesProtection and Control of Modern Power Systems, 2022
Frequency control of an interconnected power system in the presence of wind integration is complex since wind speed/power variations also affect system frequency in addition to load perturbations.

A six degree-of-freedom set-up for wind tunnel testing of floating wind turbines

open access: yesJournal of Physics, Conference Series, 2022
In this paper we present a six-degree-of-freedom (DoF) experimental set-up for wind tunnel testing of floating offshore wind turbines (FOWTs). The system is composed of a 6-DoF Stewart platform that can be used to mimic realistically the motions of a ...
