Abstract:
account their spatial work. It is shown that consideration of spatial work makes it possible to
determine the forces in individual floor slabs significantly more precise. The fact that strain
redistribution between precast floor slabs depends on slabs bending and torsional stiffness is
shown. The research has been mostly devoted to determination of the bending stiffness with regard
to formation of cracks and the change in torsional stiffness, especially considering the presence of
normal cracks, which is still unstudied.
Description:
This paper presents the technique for determining the
torsional stiffness of hollow-core slabs with normal cracks. In order to determine the components
included in the resolving system of equations, it is proposed to use an approximation method based
on the processing of numerical data using spatial finite elements
