Following the two damaging California earthquakes in 1989 (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. The FEMA 306 report, 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.

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 purpose of this document is to provide practical criteria and guidance for evaluating earthquake damage to buildings with primary lateral-force-resisting systems consisting of concrete or masonry walls or infilled frames. The procedures in this manual are intended to characterize the observed damage caused by the earthquake in terms of the loss in building performance capability. This information may be used to facilitate the settlement of insurance claims, the development of strategies for repair, or other purposes. The intended users of this document are primarily practicing engineers with experience in concrete and masonry design in seismic regions. Information in this document also may be useful to building owners, building officials insurance adjusters, and government agencies; however these users should consult with a qualified engineer for interpretation or specific application of the document.

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.
