Insulating concrete forms (ICFs) are leave-in-place forms typically produced in block or panel shapes of expanded polystyrene (EPS). They provide additional components, such as insulation and a substrate for interior and exterior finish attachment, for a wall or floor system. The most widely used ICFs are block shapes, which are stacked in an interlocking fashion to create stable formwork for creation of reinforced concrete walls. Due to the variability of these manufactured form systems, this report does not attempt to address every ICF type, but provides a commentary on those systems most prevalent in the market, and insight, as well as additional information, relative to their use in design and construction. The report focuses on ICFs for walls.

This guide identifies and suggests allocation of responsibilities to various parties involved in concrete rehabilitation in the United States; however, the guidance presented may apply to contractual relationships addressing concrete construction in other parts of the world. This guide can be useful in evaluating existing contract documents for adequacy and balance with respect to responsibilities in concrete rehabilitation projects.
In some cases, the responsibilities outlined carry the force of law. In others, there are options that could be incorporated into a particular contract.

This Specification covers requirements for strengthening concrete structures using externally bonded fiber-reinforced polymer (FRP) materials using the wet layup method. This Specification includes requirements for surface preparation of the substrate, including applying primers and putties, saturating the dry fabric, installing the fabric on the substrate, identifying and repairing defects, and field testing for quality control of the installation and materials.

Vibration problems dealing with advanced Mathematical and Numerical
Techniques have extensive application in a wide class of problems in aeronautics, aerodynamics, space science and technology, off-shore engineering and in the design of different structural components of high speed space crafts and nuclear reactors. Different classes of vibration problems dealing with complex geometries and non-linear behaviour require careful attention of scientists and engineers in pursuit of their research activities. Almost all fields of Engineering, Science and Technology, ranging from small domestic building subjected to earthquake and cyclone to the space craft venturing towards different planets, from giant ship to human skeleton, encounter problems of vibration and dynamic loading.
This being truly an interdisciplinary field, where the mathematicians, physicists and engineers could interface their innovative ideas and creative thoughts to arrive at an appropriate solution, Bengal Engineering and Science University, Shibpur, India, a premier institution for education and research in engineering, science and technology felt it appropriate to organize 8th International Conference on “Vibration Problems (ICOVP-2007)” as a part of its sesquicentenary celebration. The conference created a platform and all aspects of vibration phenomenon with the focus on the state-of-the art in theoretical, experimental and applied research areas were addressed and the scientific interaction, participated by a large gathering including eminent personalities and young research workers, generated many research areas and innovative ideas.
This proceedings being published by Spinger containing good number of
scientific research articles and state-of-the art lecture by the distinguished
scientists and engineers across the globe will definitely be a good reference for the scientists who would be working in the relevant field in theoretical,
experimental and applied research areas.
We express our sincere thanks and gratitude to all the guests, participants,
speakers, sponsors and supporters for their kind patronage and valued cooperation to make the conference a grand success. Special thanks are due to Ministry of Human Resources, Department of Science and Technology (DST), Council for Scientific and Industrial Research (CSIR), Indian Space Research Organization (ISRO), Govt. of India, Centre for Applied Mathematics and Computational Science, Saha Institute of Nuclear Physics (SINP), Kolkata, India for their kind cooperation and support for the conference and making the publication of the proceeding a reality

Modelling Steel and Composite Structures
Author(s)/Editor(s): Pedro Colmar Gonçalves da Silva Vellasco, Luciano Rodrigues Ornelas De Lima, Sebastião Arthur Lopes De Andrade, Marley Maria Bernardes Rebuzzi Vellasco and Luís Alberto Proença Simões da Silva . | Size: 58.5 MB| Format:PDF| Publisher: Butterworth-Heinemann | Year: 2017| pages: 463 | ISBN: 9780128135693
Modeling Steel and Composite Structures explains the computational tools, methods and procedures used to design steel and composite structures. The reference begins with the main models used to determine structural behavior. This is followed by a detailed description of experimental models and their main requirements and care. Numerous simulations presenting non-linear response are illustrated as are their restrictions in terms of boundary conditions, main difficulties, solution strategies and methods adopted to surpass convergence difficulties. In addition, examples of the use of computational intelligence methods to simulate steel and composite structures response are presented.

Cold formed structural members are being used more widely in routine structural design as the world steel industry moves from the production of hot-rolled section and plate to coil and strip, often with galvanised and/or painted coatings. Steel in this form is more easily delivered from the steel mill to the manufacturing plant where it is usually cold-rolled into open and closed section members.
This book not only summarises the research performed to date on cold form tubluar members and connections but also compares design rules in various standards and provides practical design examples .

This book deals with the analysis and behaviour of composite structural members that are made by joining a steel component to a concrete component. The emphasis of the book is to impart a fundamental understanding of how composite structures work, so engineers develop a feel for the behaviour of the structure, often missing when design is based solely by using codes of practice or by the direct application of prescribed equations. It is not the object to provide quick design procedures for composite members, as these are more than adequately covered by recourse to such aids as safe load tables. The subject should therefore be of interest to practising engineers, particularly if they are involved in the design of non-standard or unusual composite structures for buildings and bridges, or are involved in assessing, upgrading, strengthening or repairing existing composite structures. The fundamentals in composite construction are covered first, followed by more advanced topics that include: behaviour of mechanical and rib shear connectors; local buckling; beams with few shear connectors; moment redistribution and lateral-distortional buckling in continuous beams; longitudinal splitting; composite beams with service ducts; composite profiled beams and profiled slabs; composite columns; and the fatigue design and assessment of composite bridge beams
