A new simplified method for the design of composite slabs

The load bearing capacity of steel and concrete composite slabs using thin-walled steel sheeting with prepressed embossments is in most cases determined by its resistance in longitudinal shear. The designing of composite slabs still requires the performance of full-scale laboratory bending tests. Small-scale shear tests cannot include all of the influences affecting the bended slab but using an appropriate procedure the shear characteristics obtained from them can be used for determining the bending capacity of the slab. Two such procedures are compared in this paper.End constraints effectively increase the load bearing capacity of the composite slabs. Two different types of easily assembled additional end constraints are also tested and compared in this paper. Small-scale tests are used to obtain their shear bearing characteristics and to predict the load bearing capacity of bended slabs using these constraints.

“…The Mu versus Tu relation had been assumed to be linear by Patrick [10] . However, the conclusions in the reference [3] indicated that the linear assumption of the Mu versus Tu relation would underestimate the longitudinal shear capacity of composite slabs with profiled steel sheet. Therefore, the Mu versus Tu relation should be discussed in detail.…”

This paper presents a calculation method for predicting the ultimate loading capacity of continuous composite slabs. Only the small scale slide block test was needed to determine few mechanical parameters, and less cost had to be paid, in comparison to the conventional m-k method. Various load conditions and parameters were considered. Comparisons between test results and predicted results have shown that the proposed method has enough precision. Furthermore, the simplified method was also proposed for practical design.

“…Extensive experimental and modelling approaches are availab1e for various structural members including beam and columns (Kheyroddin and Naderpour 2007;Sheikh and Yeh 1992), composite plates and slabs (Crisinel and Marimon 2004), steel girder bridges (Barth et al 2004). Strain compatibility analysis has been used to obtain closed-form moment-curvature relationship for FRC and HRC beams, such as Taheri et al (2011) as well as Van Zijl and Mbewe (2013).…”

Abstract:Analytical solutions are developed for deflection calculations of determinate beams subjected to usual loading patterns. The solutions are based on a bilinear moment curvature response characterized by the flexural crack initiation and ultimate capacity based on a deflection hardening behavior. Equations for deflection distribution along the full length of a beam are presented for multiple cases including three-and four-point bending, which can be further extended to uniform load, concentrated moment, and cantilever beams. The proposed equations are capable of tracking the curvature, angle of rotation and deflection at any point along the beam as serviceability based design approach. A parametric study is conducted to examine the effects of moment and curvature at the ultimate stage to moment and curvature at the first crack ratios on the deflection. Results are examined for UHPC beams with different reinforcement types and test configurations. The accuracy of the present model is successfully verified.
