This program will include the development of the first version of a concrete masonry stair and elevator core design guide. Additionally, this program will include the publication and distribution of simple design tables that can be used by design engineers to quickly, easily, and efficiently design reinforced concrete masonry cores. It will focus on adapting a guide for local properties in Rocky Mountain and Northwest regions and promoting the use of the design guide and the use of concrete masonry cores through presentations to structural engineering groups.
