Single degree of freedom frame structure movements

Structural mechanics

The article reviews a behavior of statically determinate framed structure (framed one-degree structure) with one degree under different types of oscillation: - free undamped oscillations; - free damped oscillations; - constrained oscillations excluding damping; - constrained oscillations including damping. There are two primary objectives are set in the article. First one is the review of each of oscillations separately, and second one is the investigation of influence of different factors on it. Objectives are solved with numerical method of Runge-Kutta realized on Mathcad software. The comparison and the analysis of influence of coefficient of inelastic resistance of material (or construction) and frequence of external action is based on time-varying concentrated mass movement's diagram foundas a result. External action is harmonic.
