The Analysis of Slab and Beam Floor with Pre-stressed Wire Rope Reinforcement

Abstract

The paper presents calculations of monolith slab and beam floor with pre-stressed wire rope reinforcement. The numerical modeling of the slab is performed with PC “Lira-SAPR 2013”. The paper describes finite elements used in calculations, the conditions of the slab reinforcement, concrete and wire rope reinforcement connections. The calculation results are shown as stress isofields in concrete and steel elements of the slab. The paper also estimates pre-stressed wire rope reinforcement efficiency when used in slab and beam floor. The authors compare stress and strain condition of typical monolith slab and beam floor with reinforcement bars and slab and beam floor with wire rope reinforcement while changing intermediate slab thickness. The results are presented as a finite element model of monolith slab and beam floor with pre-stressed wire rope reinforcement and with untensioned reinforcement.
