Masonry walls subjected to wind-induced lateral loads and uplift
AbstractA common construction method in the United States, particularly for light commercial and public buildings, is the use of lightweight metal roof decking supported by steel bar joists which span between load bearing masonry walls. This structural system is economic and performs well for gravity loads, but when subjected to high winds, these types of structures have performed poorly. The current practices used, some in accordancϵ with model codes, for anchoring the bar joists to the masonry wall cannot transmit the uplift forces down through the wall without exceeding the ultimate bond capacity between the mortar and masonry units.The objective of this research-in-progress is to experimentally evaluate the load-deformation behavior of a typical masonry wall when subjected to combinations of lateral wind pressure and uplift forces transmitted through a bar joist anchorage. A series of tests is under way involving walls carrying uplift forces with and without the presence of lateral loads (representing outer windward walls and interior bearing walls). Walls will be tested with and without a reinforced masonry bond beam to evaluate its effectiveness in improving the strength of the wall.
