    Abstract. Buildings using a metal frame with steel-reinforced concrete floors are being erected more often. The floor disc's and frame's joint work under the uneven horizontal loads action is ensured by the shear studs setting. In modern design process computational software systems usage is necessary, however, the combined floor using profiled flooring disk model parameters influence on the results accuracy has not been sufficiently studied. So, for example, the optimal stiffness characteristics issue when determining stress-strain state under the horizontal loads action is relevant. This article examines the model various characteristics influence on the efforts determination in flexible stops. On the overlap disk section example modelled in the LIRA-SAPR software package, the anchor rods setting frequency influence, their length, as well as the studs stiffness characteristics influence is considered. It is revealed that only the shear stud simulating bar length influences on the combined floor using profiled flooring anchors calculating force accuracy. The bar's minimum length is determined, at which the result obtained in the calculation in the software package will be reliable. Depending on the stiffness, the bar's maximum length is determined. That is maximum length when the stud works in shear, not in bending. In addition, bar's part modelled as an absolutely rigid body models are considered. As a result, the bar's stiffness characteristics calculation accuracy dependence is obtained, horizontal loaded combined floor using profiled flooring modelling recommendations are given.
    Key words: combined flooring, profiled flooring, horizontal loads, bar length, shear stud, anchor.
