Design a cavity wall (specify thickness of the wall, mortar to be used, strength of masonry,strength of units, and if the wall needs to be grouted or not) for the top story of a 6-story office buildingin Galveston, Texas. The outer wythe has a vertical span of 11 feet and a horizontal span (simplysupported) of 20 feet. The inner wythe has a vertical span of 10 feet and a horizontal span (simplysupported) of 18.5 feet. Assume a uniform story height of 11 feet. Use the wind design provisions ofASCE 7-16 (consider cladding pressures as the governing wind pressure). Use an outer wythe ofstandard modular brick, and an inner wythe of hollow or grouted CMU. Use Type S portland cement-lime mortar.
