"Lu" sikrer at langtidsnedbøjningen for egenvægt er mindre end l/400 og bør anvendes ved dimensionering. "Lf" sikrer at styrken overholder normkravene. Jeg vil altid aflæse konservativt og gå efter den mindste af de to tilladelige lysvidder - så er du sikker på det holder ;)
Hi, I am in the process of rebuilding an old house, and extending it Could you tell me what books I should get to allow me to rebuild the timber external wall (145x45 timber) and the roof, in a conventional made on site timber roof, currently it is an A frame with a high level collar, and ceiling joists at wall plate level, that's what I want to replace instead of the 100 year old timber. I can't get a crane anywhere near it, nor a truck with pre made trusses I studied this at college, and worked as an on site engineer in the UK, so know what I'm doing but want the correct reference material. I do not want to use nail plates and have an outline design that is old school and conventional. Any help much appreciated. J
På spærtabellen står der ved spærvidden, lu og lf. Hvad betyder det?
Tænker det har noget at sige hvilket spær man vælger
