Book Description
Following the two damaging California earthquakes in1989 (Loma Prieta) and 1994 (Northridge), many concrete wall and masonry wall buildings were repaired using federal disaster assistance funding. The repairs were based on inconsistent criteria, giving rise to controversy regarding criteria for the repair of cracked concrete and masonry wall buildings. To help resolve this controversy, the Federal Emergency Management Agency (FEMA) initiated a project on evaluation and repair of earthquake-damaged concrete and masonry wall buildings in 1996. The ATC-43 project addresses the investigation and evaluation of earthquake damage and discusses policy issues related to the repair and upgrade of earthquake-damaged buildings. The project deals with buildings whose primary lateral-force-resisting systems consist of concrete or masonry bearing walls with flexible or rigid diaphragms, or whose vertical-load-bearing systems consist of concrete or steel frames with concrete or masonry infill panels. The intended audience is design engineers, building owners, building regulatory officials, and government agencies. The project results are reported in three documents. TheFEMA306report, Evaluation of Earthquake Damaged Concrete and Masonry Wall Buildings, Basic Procedures Manual, provides guidance on evaluating damage and analyzing future performance. Included in the document are component damage classification guides, and test and inspection guides. FEMA 307, Evaluation of Earthquake Damaged Concrete and Masonry Wall Buildings, Technical Resources, contains supplemental information including results from a theoretical analysis of the effects of prior damage on single-degree-of-freedom mathematical models, additional background information on the component guides, and an example of the application of the basic procedures. FEMA 308, The Repair of Earthquake Damaged Concrete and Masonry Wall Buildings ,discusses the policy issues pertaining to the repair of earthquake-damaged buildings and illustrates how the procedures developed for the project can be used to provide a technically sound basis for policy decisions. It also provides guidance for the repair of damaged components.

Book Description
This report provides guidance for engineers to use in strengthening buildings found to be deficient in seismic resistance. The guidance is intended to serve as the basis for criteria for determining the suitability of specific strengthening schemes for a building and applying specific strengthening methods. Various strengthening methods which have been used in the past are reviewed, with emphasis given to those most applicable to Army needs. Detailed guidelines for the application of two methods-pneumatic application of concrete and use of epoxy compounds-are provided, along with advantages and disadvantages of each. (Author).

Book Description
Understanding and recognising failure mechanisms in concrete is a fundamental pre-requisite to determining the type of repair, or whether a repair is feasible. This title provides a review of concrete deterioration and damage, as well as looking at the problem of defects in concrete. It also discusses condition assessment and repair techniques. Part one discusses failure mechanisms in concrete and covers topics such as causes and mechanisms of deterioration in reinforced concrete, types of damage in concrete structures, types and causes of cracking and condition assessment of concrete structures. Part two reviews the repair of concrete structures with coverage of themes such as standards and guidelines for repairing concrete structures, methods of crack repair, repair materials, bonded concrete overlays, repairing and retrofitting concrete structures with fiber-reinforced polymers, patching deteriorated concrete structures and durability of repaired concrete. With its distinguished editor and international team of contributors, Failure and repair of concrete structures is a standard reference for civil engineers, architects and anyone working in the construction sector, as well as those concerned with ensuring the safety of concrete structures. Provides a review of concrete deterioration and damage Discusses condition assessment and repair techniques, standards and guidelines

Book Description
The purpose of this document is to present practical guidance for the repair and upgrading of earthquake damaged buildings with primary lateral-force-resisting systems consisting of concrete bearing walls, masonry bearing walls, or infilled frames. The guidance consists of a policy framework for facilitating the determination of the appropriate scope of repair or upgrading measures. This document also includes outlines of specific repair techniques that can address the component damage common to these buildings. The criteria and procedures are based on the evaluation of the anticipated seismic performance of a subject building at three different times: in its condition immediately before the damaging earthquake (pre event), in its damaged condition, and in its repaired or upgraded condition. This document may be used as a technical resource to facilitate the settlement of insurance claims, the development of policy and strategy for repair, or other appropriate purposes. The intended users of the document are design engineers, building owners, building officials, insurance adjusters, and government agencies.

Book Description
This manual provides guidance on evaluating the condition of the concrete in a structure, relating the condition of the concrete to the underlying cause or causes of that condition, selecting an appropriate repair material and method for any deficiency found, and using the selected materials and methods to repair or rehabilitate the structure. Guidance is also included on maintenance of concrete and on preparation of concrete investigation reports for repair and rehabilitation projects. Considerations for certain specialized types of rehabilitation projects are also given.
