AB Analysis of response of bed construction on mentioned mechanical loading with geometry derived from design documentation and selected material combination was realized. In terms of discussed results can be say that chosen geometry (combination of material models) is not appropriate. It can be assumed, that stress will exceed strength values in bed side-rail and some failure of cracks can occur. According to the fact that the task does not include free constraints of bed grid and this way probably increases the whole stiffness of construction some solutions present itself for decreasing of carrying-capacity in form of bed side-rail change or adding of supplemental supports to the current construction.As we mentioned above, parametric model is sufficiently complex for realization of optimization analysis of geometry. However, before this analysis extended investigation of verification of mechanical material properties, which are taking into account for installation of construction, definition of complex way of loading and derivation of appropriate failure criterions for wood construction parts should be considered.
