  • Concrete has been in use as a primary building material since Roman times. As it is strong in compression but weak in tension, it was used in arches, vaults and walls where it is stressed principally in compression. In the mid-nineteenth century, it was discovered that iron and later steel bars could be embedded in the concrete, effectively giving it tensile strength. This allowed it to be used in beams and slabs, where it worked in bending. Buildings, bridges, retaining walls and many other structures were made in this reinforced concrete.

  • number of books on various aspects of concrete design and detailing have been published but this is believed to be the first comprehensive detailing manual. The aim of this book is to cover a wide range of topics, so simplifying and reducing the work required to prepare structural drawings and details in reinforced, prestressed, precast and composite concrete. The book initially provides a list of extracts from relevant codes and current practices. Where drawings are carried out using imperial units, a conversion table is provided to change them into SI units.

  • Fiber Reinforced Polymers are by no means new to this world. It is only because of our fascination with petrochemical and non-petrochemical products that these wonderful materials exist. In fact, the polymers can be considered and used in the construction and construction repair. The petrochemical polymers are of low cost and are used more that natural materials.

  • It is necessary for concrete structure with mass section to have a rational crack control plan based on analysis of thermal stress from hydration heat. Because mass concrete can cause crack to deteriorate durability of structure. So, this study reports two examples: one is a process to calculate an adiabatic temperature rise and a reaction rate for evaluate thermal stress.

  • The impetus for the preparation of a second edition of the Guide to Design Criteria for Bolted and Riveted Joints has been the enthusiastic reception of the original version and the continued citation for over a decade of that book as a source of information regarding the design of bolted connections. There certainly has been no other single reference in this area that has been so accepted by designers, teachers, students, and specification writers.
