I have a problem with Ufin and Uinst displacement on timber beam. There are three load cases: dead load, snow and wind. I dont know why, but the final displacement has no wind load in SLS/QPR combinations. Also Uinst has no dead load and wind load. In calculation of displacement should be considered all three load cases, althroug the PSI2 factors for snow and wind are 0 (zerro). i dont know where is the problem in calculation.
Problem with beam numbber 26,25,24,6 27. I think that calculation for Ufin and Uinst are not right in all cases. In general are this calculation i think wrong... There are no dead load in calculation od Uinst?
