Rapid urban development in recent decades has seen cities are now increasingly more populated, as witnessed by the rise of megacities across the world. These trends pose critical challenges to managing infrastructure in a densely build-up urban environment. The constraints of limited land in mega cities have forced buildings to be built higher. Planners and architects have faced the challenge of designing taller buildings and long span bridges with the optimum use of steel and concrete materials to achieve speed and economy. A good balance is sought to improve buildability, quality, and labour productivity and to reduce construction time, material usage and wastage. Steel concrete composite construction, which encourages the use of prefabrication and precast components, coupling with advancement in fabrication and material technology, has accelerated the adoption of a number of innovations which lead to an overall improvement of productivity in construction. New construction technologies are also emerging together with new products, such as high strength steel, composite steel, weather resistant and fire resistant steel which are suitable for use in the tropical and urban environment. The move to green and sustainable design to accommodate large span column free space and the intensive service requirements of the building tenant has brought in new design challenges.

Steel concrete composite systems are increasingly being employed to produce innovative and spectacular architectural designs with complex geometrical problems. This is made possible with the advancement in design expertise, metallurgy research, fabrication technology and construction technique, and more importantly, the close cooperation and commitment of architects, engineers, suppliers, fabricators and erectors, sharing knowledge through building information model and working as a team to ensure successful transformation of an innovative design to a successful completed project of architectural and structural marvel.

The set of conference proceedings is a collection of papers presented in the 10th International Conference on Advances in Steel Concrete Composite and Hybrid Structures held in Singapore from 2 to 4 July 2012. The conference is jointly organized by the National University of Singapore and the Singapore Structural Steel Society. The conference was managed by a Local Organisation Committee (LOC) with strong supports from Yongnam Engineering and Construction Pte Ltd, TTJ Design and Engineering Pte Ltd, Continental Steel Pte Ltd, Lee Foundation, and other companies from the steel industry.

This conference has attracted 155 contributions from 28 countries including 9 keynotes papers covering a wide spectrum of topics including composite beams; composite bridges; composite columns; composite coupled wall; composite slabs; CFRP composite structures; dynamics, earthquake and impact; fire engineering; hybrid structures; progressive collapse; steel and composite connections; structural analysis; shear connections; thin-walled structures and sustainable design. All the papers were peer reviewed and selected based on their own merits. The LOC wishes to thank the members of the international scientific committee for their role in promoting and contributing articles to the conference. The roles of many reviewers who help to assess and review more than 200 abstracts and 180 papers are greatly appreciated. We like to acknowledge the keynote speakers for their excellent contributions to the success of the ASCCS 2012 conference. The keynote speakers are all international experts in their respective field and have contributed to iconic projects, national and international specifications in the fields of steel and composite structures in America, Australia, China, Europe, Hong Kong, Korea and Singapore. Finally, the LOC wishes to thank all the presenters for their excellent contributions to the success of the ASCCS 2012 conference.
