Good seismic performance of confined masonry (CM) buildings and significant global spread of this technology has been the main motivating factor for establishing a joint Confined Masonry working group between The Masonry Society (TMS) and the EERI in July 2018. EERI has had a long-term engagement in developing resources on CM construction through its Confined Masonry Network, which was established in 2008 (CMN, 2018). EERI has recently released a Policy Statement related to CM construction that can be used by EERI members to promote and encourage action by policy makers to reduce earth-quake risk (EERI 2018). TMS has a mission to advance masonry knowledge, its development and application and is responsible for TMS 402/602 which has been adopted by the International Build-ing Code for the design and construction of masonry.  Current activities of the TMS-EERI CM Working Group are related to a survey and analysis of global seismic design provisions for CM buildings. The other objectives of the initiative are to investigate the percentage of the global construction market built with CM and provide recommendations for future research and code provisions. Co-chairs of the group are Matt Reiter, USA (M. TMS) and Svetlana Brzev, Canada/Serbia (M. EERI and TMS), and the members are: Tim Hart, USA (M. EERI), Daniel Quiun, Peru (M. TMS), Juan José Pérez Gavilán Escalante (M. EERI), David Sommer (M. TMS), and Mark Membreño, USA (M. EERI).
