“…For composite slabs with end anchorage such as a welded stud, the slip at the profiled steel sheet-concrete interface can be reduced, whereas the bond between the steel sheet and concrete can be enhanced. Consequently, their strength and rigidity can be improved [9][10][11][12].…”

“…Moreover, the shear strength of the composite slabs was mainly governed by the same property of the shear span. Based on an investigation of the effect of end-anchorage studs on the longitudinal shear strength of composite slabs, Chen et al [9] suggested that the contribution of the studs to the longitudinal shear bearing capacity of the composite slab was not simply an addition of the shear strengths of the individual studs.…”

This paper presents an experimental study on the structural performance of 26 composite slab specimens having trapezoidal and dovetail profiles. The influence of the span, details of the end anchorage, and cross -sectional depth on the mechanical performance and failure modes of the specimens was discussed. The effects of the thickness of the profiled steel sheets and additional reinforcement of the bottom on the longitudinal shear bearing capacity of long -span dovetail-profiled composite slabs were also investigated. Research on long-span composite slabs accounting for different details of the end anchorage and steel profiles is limited in the literature. The test results indicated that the end anchorage can significantly improve the mechanical performance and ultimate bearing capacity of composite slabs, whereas additional reinforcement and thick profiled steel sheets can slightly increase their bearing capacity. The test results also showed that, in long-span flooring systems, dovetail-profiled composite slabs have a higher load bearing capacity than trapezoidal-profiled composite slabs.

“…Following an axial tension test on two notched rebar specimens to test the system, four-point bending tests of RC beams with embedded and external fibre optic strain sensors were carried out. While the results of the exercise did not produce a definitive conclusion on the utility of the proposed methodology, they do suggest that there is potential but considerable challenges remain to be overcome.The fifth paper (Chen et al, 2015) attempted to quantify the strength enhancement of the widely used profiled composite deck slabs by enforcing composite action between the steel deck and the concrete using shear stud connectors at the ends as anchorages. This is done by developing a finite-element model and validating against load testing of thirty six slabs.…”

This issue presents an exciting set of six papers covering a wide range of topics in the broad context of structures and buildings. It leads with two very interesting reviews: one exploring the state of the art in the rapidly maturing field of building information modelling (BIM); followed by an equally fascinating review of how engineers grapple with the enormous complexity associated with fluid-structure interactions in the context of long-span bridges. The two following papers involve strain measurement in cast-iron tunnel linings in the London Underground; and the use of distributed fibre optic sensors to measure localised strains such as those resulting from reinforcement corrosion. The penultimate article investigates the enhancement of the strength of profiled composite deck slabs brought about by introducing end-anchorages. The final paper presents an improved model of slender rectangular reinforced-concrete (RC) column buckling using an energybased approach.The first paper (Gilkinson et al., 2015) presents a practical review of the BIM concept with the help of six interesting case studies in Europe and Australia and offer useful insights into the use of this process. Despite considerable potential benefits, BIM in its full form is yet to be widely adopted, however, its most recognisable components, such as computer-aided design are being used and are evolving. The authors also point out that recent changes to UK government policy will require companies bidding for public sector projects to be BIM-ready to secure a contract therefore engineering companies should include BIM in their strategic planning.In the second paper, Kareem and Wu (2015) present a comprehensive review of how the complex interaction of wind with long-span bridge cross-sections are dealt with by engineers, beginning with simple models that ignore much of the non-linear and unsteady behaviour to advanced methodologies that attempt to include more and more of the complexity short of full computational fluid dynamics modelling. This review presents a relatively complex topic in a language that should be accessible to most readers.The third paper (Yu et al., 2015) stems from taking advantage of major works on the Northern line at Tottenham Court Road London Underground station in anticipation of increased footfall expected after completion of the Crossrail project. The paper describes the instrumentation installed on segments of tunnel linings to be removed, and on those that were to remain in situ, in order to record the changes in the strain and deformation during the process. Predictions made before the process of removal were found to be similar to the measured strains.In the fourth paper, Regier and Hoult (2015) present an investigation of the potential of distributed sensors (in this case fibre optic cable) in monitoring the long-term damage (e.g. through corrosion) in steel reinforcement bars in RC beams. Following an axial tension test on two notched rebar specimens to test the system, four-point bending tests of RC beams with emb...
