The Effect of the Bedding Length of Lintel in Masonry Walls on Their Load Bearing Capacity

By using the previously developed numerical model of the authors for both, static and dynamic analysis of concrete and masonry structures, which can simulate their main nonlinear effects, the influence of the bedding length of lintel on the ultimate bearing capacity of some masonry walls with openings has been investigated. Three- storey masonry walls with door openings were analyzed. Unreinforced and confined masonry walls were considered. There were separately analyzed masonry walls under horizontal static forces at the floor levels and masonry walls under earthquake. The bedding length of the lintel reinforcement and quality of the masonry were varied. Characteristic displacements of the walls and crack states in the lintel’s area are presented. Finally, main conclusions and recommendations for practical application are given.
