Abstract
The aim of the study is to analyze the floor structures of a wooden frame building, made with the use of glued CLT - panels and the use of perspective wood material of their unidirectional veneer – LVL-bar, which has enhanced strength characteristics compared to ordinary wood. Four options for securing floor slabs were considered. Analysis of the stress-strain state (VAT) of the CLT-panel design with lamellae of LVL-beam is performed using the MSC Nastran finite element analysis application package. The CLT panel is approximated by four-node LAMINATE type layered elements that take into account all internal force factors: membrane, shear, transverse and flexural. At each node, the element has six degrees of freedom: three translational along each of the axes ox, oy, oz and three rotational with respect to the axes ox, oy, oz. Analysis of the results of the calculations made it possible to evaluate the most effective design solutions for floor slabs of frame buildings using CLT panels.
