Abstract
Material properties under dynamic loads are important to calculate for engineering applications. Investigation of dynamic loads of steel-concrete structures requires the development of new calculation and design techniques.
Purpose: The aim of the paper is to investigate the effect of longitudinal force on the dynamic behavior of steel-concrete bars under different dynamic loads.
Methodology: Experimental modelling based on up-to-date measuring devices and analytical processing of the obtained results.
Research findings: Vibration damping and inelastic work coefficients are determined for the dynamic system analysis in near-resonance zones. Dependences are suggested for the free oscillation frequency and amplitude, and the longitudinal compressive force and pulse power.
Practical implications: The results obtained can be used to develop new calculation and design techniques for steel-concrete structures and numerical simulation program data seed with steel-concrete properties through field tests.
Originality: Experimental research into the dynamic behavior of steel-concrete bars under different harmonic loading with regard to a stepwise increase of the longitudinal compressive force.
