Applied aspects of the application of a computational complex for modeling a multi-void monolithic overlap
Incoming article date: 26.10.2021An overview of the rationale for the use of lightweight multi-hollow floor slabs is given. Technological and design features of multi-hollow floor slabs are considered. The possibilities of rational use and labor intensity of lightweight hollow floor slabs are presented. On the basis of existing technologies, calculation methods for lightweight hollow slabs and current norms, the calculation of monolithic slabs in the Lira software package was carried out. The work of floor slabs with spans equal in two directions is considered. It was found that regardless of the span of the floor slab, the effect of reducing its own weight exceeds the effect of reducing the cruelty of the section. The total deflection from the floor slab's own weight and payload on it for hollow slabs is lower than for solid slabs of the same span.The conducted numerical experiment allows us to establish the limits of the effectiveness of the use of lightweight multi-hollow monolithic floor slabs, upon reaching which the use turns out to be significantly more profitable than the use of traditional girderless floors.
