Strengthening Klein’s floor slabs with the use of current norms

The paper presents the effectivity of using the steel-concrete floor slabs in existing buildings. Steel-concrete slabs described in this paper consist of old steel beams which are main structural members of the floor slabs and reinforced concrete slabs which are new elements of the floor slabs. Beams and reinforced concrete slabs are connected with connectors. The computational example which shows the efficiency of utilizing the steel-concrete floor slabs with the use of current norms has been presented in the paper.
