%0 Journal Article %T Carrying Capacity and Serviceability Parametric Analysis of Pre-Stressed Concrete Roof Purline %A Radim ajka %A Pavl¨ªna Mate kov¨¢ %J Transactions of the V£¿B - Technical University of Ostrava. Construction Series %@ 1804-4824 %D 2010 %I %R 10.2478/v10160-010-0001-8 %X This paper deals with different computational methods of pre-stressed components according to formerly valid CSN and Eurocode system 1992-1-1 (next only EC2). The different computational methods are applied on a particular component of a pre-stressed prefabricated concrete roof purlin with a span of 16 m. The limit state of serviceability has been analyzed in relation to relative humidity and the dead and live load ratio. %K Prefabricated concrete %K pre-stressed concrete %K roof purlin %K limit strain %K ultimate deflection %U http://versita.metapress.com/content/e3810v28r4673652/?p=c0b6b985dea249b1818f204112b17df9&pi=0
