Abstract: Steel is an integral part of any concrete construction either in the form of anchors connecting structural/non-structural components to the structure or in the form of reinforcement embedded in concrete or sometimes as a part of steel-concrete composite construction. To ensure structural integrity, it is essential to form a reliable connection between steel and concrete. The anchorage must serve its function well to ensure the interaction between the components connected to the structure and the structure itself. The bond between reinforcement and concrete must be ensured to maintain the required flow of forces from concrete to steel and vice-versa. The concrete and steel structural members must be able to interact with each other in a desired way. If the connection between steel and concrete loses its integrity, the integrity of the entire structure comes in jeopardy. In order to ensure the integrity of connections between steel and concrete, it is required to (i) investigate their behavior through high quality experiments, (ii) evaluate their performance with advanced and reliable computational methods, and (iii) summarize them in practical and reliable design rules and models to be used by engineers and practitioners. Although connections between steel and concrete are used ever since the commencement of reinforced concrete construction, there are several aspects which are yet to be fully understood. Advancement in technologies lead to development of new products such as post-installed anchors, anchor channels, high strength reinforcing bars etc., whose performance in concrete need to be investigated. New concrete based materials such as high performance concrete, fiber reinforced concrete, geopolymer concrete etc. are being developed and their compatibility with the steel components and rebar must be verified. The interaction between structure and the anchorages or concrete and steel structure connected through anchorages need to be understood. Innovative fastening solutions between steel and concrete components are being developed for which reliable design models are needed. Furthermore, several general design issues, e.g. anchorages with supplementary reinforcement, fatigue behavior of anchors, long term performance of bonded anchors, anchor channels under different loading combinations, harmonization of design between post-installed and cast-in place reinforcing bars, influence of corrosion on performance of anchorages and reinforcement etc. need in-depth investigations. In addition, globally, structures are exposed to natural and man-made hazards more than ever, which induce extreme loads on the structural components, e.g. earthquakes, fire, impact and combinations thereof. The performance of existing structures against such hazards has exposed several inherent weaknesses in the past. Often, the performance of structures under such hazards is significantly influenced by the performance of connections between steel and concrete. Since the loads induced in the structures by such hazards cannot be reliably estimated and also since under such loads, compatibility requirements between different components result in additional demands on different components, the designs can only be reliably done following a performance based design approach. Similar approaches must also be developed for the design of connections between steel and concrete to ensure a reliable performance from the connections and in turn from the structures against extreme hazards. One of the most important applications of anchorages is in strengthening of structures for connecting the strengthening element and the parent structure. Every strengthening needs a certain type of anchorage and the performance of the strengthening depends largely on the performance of the anchorage itself. The demands posed on the anchorages used in strengthening (e.g. seismic strengthening) could be very challenging, which includes high forces, large crack widths, combined load and crack cycling, limited area and depth to develop the required resistance etc. In order to ensure the safety of structures, therefore, it is essential to develop innovative strengthening methods along with anchorage techniques that would allow the strengthening to serve its desired function. The 3rd International Symposium on Connections between Steel and Concrete (ConSC2017) aims at bringing the experts from around the globe working in the field of steel-concrete connections to share and discuss the current state-of-the-art as well as the possible future directions to improve the safety of structures by making reliable connections between steel and concrete. The previous two symposia were held in Stuttgart in 2001 and 2007. This symposium offers a platform for the academicians, researchers, industry, regulatory authorities, practicing engineers and students to share the knowledge gained through a decade of research and development. With more than 120 high quality research papers along with the keynote addresses and invited lectures from the renowned experts, this symposium is a significant step forward towards the enhancement of knowledge as well as to provide food for thought for the forthcoming research in the field of connections between steel and concrete.
