Foundation repair system
Developed by professional engineers at Nationwide Reinforcing Ltd., The Reinforcer is an externally bonded, 4-inch-wide and .045-inch-thick strip or strap made of carbon fiber reinforced polymer that is ideal for repair of bowed walls. The lightweight, non-corrosive material is virtually impossible to stretch; having a tensile strength of more than 350,000 pounds per square inch (psi), making it 10 times stronger than steel (which has a tensile strength of 36,000 psi). The company also produces a unidirectional sheet/fabric made with high-strength carbon or glass fibers called The Reinforcer Shield. This product provides the capability of conforming to irregular shapes such as circular or square columns. It can be used for flexural and shear strengthening and provides a water-proofing membrane for foundation walls. The Reinforcer comes with a lifetime manufacturer’s warranty.

Concrete provisions guide
With an extended commentary, comparisons, and design examples, you can reinforce your concrete knowledge with the International Code Council’s Application Guide for the 2003 IBC Concrete Provisions (Chapter 19). The new guide provides background on the concrete chapter, Chapter 19, of the 2003 International Building Code (IBC) and will help firm up your understanding of the code and referenced standards. The guide is divided into three parts in a clear, easy-to-read writing style. Part 1 provides code commentary and explains how the code text differs from the previous edition. Part 2 addresses the differences between the primary standard of reference in the 2003 IBC versus the 2000 edition. Part 3 includes design examples to clarify the proper application of different code provisions.

Foundation wall repair
CINTEC America of Baltimore, a structural masonry retrofit strengthening, repair, and preservation consultant, uses its earth retaining stabilization system to tie back historically sensitive walls or in difficult situations where the historic nature of the project has to be preserved. In 1983, the first such application involved the use of Seadoos anchors to tie back a protective sea wall in Florida. Highly versatile, this stabilizing system offers a solution tailored to meet the specific requirements of each structure.
At the site, ground anchors provide stability, while voids and gaps within the structure are bridged using a cement-like grout.
CINTEC’s earth retaining wall and ground anchoring system is ideal for many difficult ground conditions, including sand, gravel, clay, limestone, broken brick, and stone.

Combination resource
The Portland Cement Association (PCA) combined its PCA Notes on ACI 318-05 Building Code Requirements for Structural Concrete with Design Applications and the American Concrete Institute’s Building Code Requirements for Structural Concrete and Commentary (ACI 318-05) on one searchable CD to provide a better understanding of code requirements. The ACI 318-05 and PCA Notes on CD electronically links explanations from notes to the corresponding code sections to help designers apply the provisions. Adobe Acrobat can be used to search, find, and print the information needed. The CD’s discussions on codes applicable to strutand- tie models, alternative provisions for reinforced and prestressed concrete flexural and compression members, alternative load and strength-reduction factors, and anchorage to concrete begin with what code changes have taken place, followed by numerical examples that allow design professionals to better understand and apply the code provisions.

Concrete practice manual
The 2006 Manual of Concrete Practice from the American Concrete Institute (ACI), contains more than 180 of ACI’s committee standards and reports, and is arguably the most comprehensive reference set available. It contains all of the widely used ACI concrete and masonry code requirements, specifications, guides, and reports. Additionally, it includes information about code requirements, cracking, durability problems, temperature control, nondestructive testing, and hundreds of other topic areas.
