1. Introduction
The use of profiled deck composite slab in the construction industry has many advantages including the simplicity in construction compared to other flooring system. The profiled sheeting serve's as shuttering by shouldering wet concrete during construction stage, for example. This composite construction method gained popularity for eliminating time-consuming erection and subsequent removal of temporary forms [1–3]. The composite action between the profiled sheeting deck and the hardened concrete will come into play with effective development of longitudinal shear at the steel-concrete interface. Several studies [4–7] shows the behaviour of profiled deck composite slab is affected by the bond failure in the longitudinal direction. Intuitively, longitudinal shear capacity determines the ultimate strength of profiled deck composite slab. [8]. The use of bonding adhesion or mechanical interlock greatly enhances the shear resistance between steel sheeting deck and concrete [9,10]. The metal deck embossing provides equivalent shear resistance characteristics for effective composite action between sheeting deck and hardened concrete similar to those mentioned previously [9,11]. A number of factors are known to affect the longitudinal shear capacity; for example the type and level of embossment, the steel strain, shear span length, etc..[10], and these hinders the deterministic based strength capacity model development for profiled composite slab (PCS). Besides those factors, the shear strength parameters are determined only after the capital-intensive laboratory procedures, and this could be through the slope-intercept, the partial shear connection (PSC) methods amongst others. These drawbacks constitute a serious challenge in developing a numerical strength determination model considering the associated random variabilities [12]. Despite several research attempts [13–15], the complex interface between profiled sheeting deck and the concrete hinders the much needed breakthrough in the development for simplified procedure for strength determination of profiled deck composite slab using PSC method. The objective of this probabilistic study is to define the safety bounds, and develop a simplified numerical model for determining the shear strength parameters for PCS devoid of expensive laboratory works.
