Abstract:The behaviour of thin-walled Z-section beam subjected to gravity load for different variants of lateral restraints is analyzed. For the basic variant of the laterally restrained beam the one defined in Eurocode 3 (EN 1993-1-3:2006) is taken. The Z-section beam which is laterally ...

Abstract:Zbog anizotropije tkanina Poissonov koeficijent se mijenja tijekom istezanja uzorka tkanine. U radu se istražuje utjecaj gustoće potke na veličinu Poissonovog koeficijenta kada na tkaninu djeluje jednoosna vlačna sila. Mjerenja prekidne sile i prekidnog istezanja provedena s...
