Abstrakty

PL

Opisano badania nad organicznym systemem sprężania (OPS) oraz jego rozwój i zastosowania. Przedstawiono etapy analizy numerycznej i eksperymentalnej oraz pierwsze zastosowanie konstrukcji dźwigara przesuwnego o naturalnej wielkości, wzmocnionego systemem OPS. Podsumowanie zawiera krótki opis innych zastosowań OPS oraz wnioski.

EN

An overview of organic prestressing system (OPS) research, development and application project is presented. After the main concept presentation, highlights of numerical and experimental analysis research stages are pointed out. The first full scale application of a launching gantry strengthened with OPS is synthetically described and the constructor's perspective is presented. Finally, other OPS applications are shortly mentioned and conclusions are established.
