Abstract
The article describes the features of design and calculation of ribbed slabs on wooden frame with trapezoidal plan, in which the cover is included in the general work of the structure on operational loads. The field of possible application of the investigated elements is shown. Features of trapezoidal slab design are described. The main provisions of the proposed method of calculation of the considered class of structures are reflected. Formula dependencies of calculation of trapezoidal slabs on deformations are determined using the calculation method of structures consisting of different module materials, results of previous numerical studies carried out by authors of the paper, as well as algorithms of numerical determination of functions on the basis of the method of a certain integral. Location of hazardous section of slab at calculation on normal tension is calculated taking into account part of operating cover, which varies along the span length. It is shown that the proposed technique makes it possible to adequately assess the stress-deformed state of trapezoidal slabs and to calculate them on strength and rigidity according to the proposed algorithm.
