Abstract
A sharp increase in the volume of housing construction and a lack of roofing materials set a serious challenge to find alternative options for the roof of residential buildings and structures. This demands the involvement of a large amount of new advanced roofing materials, both for refurbished and renovated residential buildings. Numerical and experimental studies of the stress-strain state of the roof structure made of cement-bonded particle boards, supported on elastically deformable lathing under the influence of short-term and long-term loads was carried out. The studies show that roof structures using cement bonded particle boards on wooden battens meet the requirements for load-bearing structures, and when calculating a cement bonded particle board as a thin elastic slab operating in bending, the values of the maximum moments and deformations are much less than the corresponding values obtained when calculating a cement bonded particle board according to a two-span beam scheme. Experiments of CBPB roof structures have confirmed the reliability of numerical studies and allow to recommend the developed approximate method for calculating the strength and deformability of CBPB in the roof for practical calculations.
