Experimental Verification of Design Models in a Static and Dynamic Loading Test

Abstract:

Nowadays more and more often investors and constructors are building constructions by combining two of the most common materials: reinforced concrete and steel. By understanding their behavior we can squeeze a mountain of used material with better results. They make it possible to take advantage of good mechanical properties of concrete in compression and steel in tension. One of the commonest types of composite structures is deck bridges with encased filler beams. These types of construction have been employed in Slovakia and all over Europe without any major change since the beginning of the 19th century. Several steel sections of modified shapes and dimensions were designed and tested in the Laboratories of the Institute of Structural Engineering at the Technical University in Košice. The main goal was to design and experiment with deck bridges made of various sections so as to maximise their cost-effectiveness by reducing the amount of steel consumed. Based on theoretical analyses, specimens were prepared in the laboratory, consisting of a variety of fully encased steel sections. It was cast into the prepared steel formwork placed on a fixed bearing plate so as to prevent deflection of composite beams during the concreting process.
