Artykuł przybliża czytelnikowi analizę MES węzłów stalowych obarczonych imperfekcjami w strefie styku blachy czołowej. Zawarto w nim podstawowe informacje dotyczące imperfekcji oraz charakterystyk sztywnościowych węzłów doczołowych. Pokazano przebieg tworzenia modelu obliczeniowego oraz rezultaty wynikające z analizy MES.
The main aim of this work is a computational nonlinear analysis of a high strength steel corrugated-web plate girder with a very detailed and realistic mesh including vertical ribs, all the fillet welds and supporting areas. The analysis is carried out to verify mechanical structural response under transient fire temperature conditions accounting for an efficiency and accuracy of three various transient...
