Formulation and System Identification of the Equations of Motion for a Dynamic Wind Tunnel Facility. [PDF]

open access: yes, 2008
This document describes the equations of motion of an aircraft model tested in Cranfield’s 4 degreeof- freedom (DoF) wind tunnel facility. In previous research, the equations have been derived assuming that the model’s centre of gravity (cg) is ...

Fatigue Performance of Reinforced Concrete T-Girders under Cyclic Loading

open access: yesAdvances in Civil Engineering, 2021
This paper examines the performance of reinforced concrete girders under cyclic loading. Seven T-girders were casted and tested. All girders were loaded under different constant cyclic loading in the midspan with the load ratio of 0.14∼0.23 and frequency
