Behaviour of a concrete slab in compression in composite steel-concrete frame joints

Popis výsledku v původním jazyce

The objective of this research is a concrete slab in compression in composite steel-concrete joint. EN 1998-1 prescribes a simplified formula and it describes two mecha-nisms. The standard procedure for calculating the effective width of the slab is inaccurate, as it is stated repeatedly in a number of publications. Mechanism 1 acts in the concrete slab with a concentrated compressive force on the column flange. In the standard proce-dure for calculating the bearing capacity of this mechanism, the positive effect of the state of stress in the concrete slab in the joint region is not taken into account. The goal of this research is to derive more accurate formula for calculation of effective width of fibre-reinforced concrete slab in compression in the nodal zone. New aspects have been taken into account: confinement effect of the mecha-nism 1 and more precise inclinations of concrete struts. An experiments, a validation of a numerical models and a parametric study of the composite joints with slab made of common concrete and fiber-reinforced concrete are main steps of this research.
