Design of Seismic Isolated Structures

This supplement contains adjustment factors, dimensions, factored resistance, reference strengths and other properties required to design structural-use panels in the LRFD format. In this format, the term “resistance” is used to refer to member capacities (i.e., moment resistance, compression resistance, etc.). This is distinct from the term “strength” which refers to limit state material properties — conceptually a “factored allowable stress.”

The member resistance values tabulated in this supplement are to be used in conjunction with the design methodologies provided in AF&PA/ASCE 16-95, Standard for Load and Resistance Factor Desig(LRFD) for Engineered Wood Construction.
The reference strengths were derived according to the principles of ASTM D5457-93, Standard Specification for Computing the Reference Resistance of Wood-based Materials and Structural Connections for Load and Resistance Factor Design.
The tabulated reference strength values are to be used within the reference end-use conditions defined therein. When the end-use conditions fall outside the range of the reference conditions, the reference values shall be adjusted by the product of applicable adjustment factors as defined in AF&PA/ASCE 16-95 and also provided in this supplement. For unusual end-use conditions, the designer should consult additional literature for possible further adjustments.

FRP Composites for Reinforced and Prestressed Concrete Structures: a guide to fundamentals and design for repair and retrofit

Product Description
High strength fibre composites (FRPs) have been used with civil structures since the 1980s, mostly in the repair, strengthening and retrofitting of concrete structures. This has attracted considerable research, and the industry has expanded exponentially in the last decade. Design guidelines have been developed by professional organizations in a number of countries including USA, Japan, Europe and China. Until now designers have had no publication which provides practical guidance or accessible coverage of the fundamentals.

This book fills this void. It deals with the fundamentals of composites, and basic design principles, and provides step-by-step guidelines for design. Its main theme is the repair and retrofit of un-reinforced, reinforced and prestressed concrete structures using carbon, glass and other high strength fibre composites. In the case of beams, the focus is on their strengthening for flexure and shear or their stiffening.The main interest with columns is the improvement of their ductility; and both strengthening and ductility improvement of un-reinforced structures are covered. Methods for evaluating the strengthened structures are presented. Step by step procedures are set out, including flow charts, for the various structural components, and design examples and practice problems are used to illustrate. As infrastructures ages worldwide, and its demolition and replacement becomes less of an option, the need for repair and retrofit of existing facilities will increase. Besides its audience of design professionals, this book will suit graduate and advanced undergraduate students. It will also serve as a basic guide for researchers.

This Manual includes state-of-the-art information relative to materials, post-tensioning systems, construction practices and grouting of post-tensioning tendons for bridges. The Manual is targeted at Federal, State and local transportation department and private company personnel that may be involved in the design, inspection, construction or maintenance of bridges that contain post-tensioning tendons. This Manual will serve as a reference and guide to designers, inspectors and construction personnel for post-tensioning materials, installation and grouting of bridge tendons. The document is part of the Federal Highway Administration’s national technology deployment program and may serve as a training manual.
