From 1984 to 1994, 19 researchers conducted the most extensive research program ever into the development of a limit-state design standard for masonry buildings in seismic zones. These researchers comprised the Technical Coordinating Committee for Masonry Research (TCCMAR) that conducted this $3 million research program, and they represented government, universities, engineering firms and the masonry industry. The National Science Foundation, other government agencies and several masonry industry organizations funded their work. This article highlights recommendations on materials, construction practice and quality assurance that are described in the final report on TCCMAR. Meanwhile, work continues to incorporate a true limit-state design standard for masonry into the next version of the Masonry Standards Joint Committee's ACI 530/ASCE 5/TMS 402 Building Code Requirements for Masonry Structures (MSJC Code), using TCCMAR's enormous data bank on masonry seismic design. If the MSJC approves these provisions they will be incorporated into the International Building Code (IBC), which is under development. TCCMAR findings have also been incorporated into strength-design provisions of the National Earthquake Hazard Reduction Program (NEHRP), which was developed by the Federal Emergency Management Agency (FEMA).
