The Design of Reinforced Masonry and Precast Concrete Lintels AIA HSW
Stuart, P.E., S.E., P.Eng.
The focus of this one hour online course is the design of reinforced concrete masonry lintels (commonly referred to as bond beams) and precast reinforced concrete lintels. Information is also provided on the how loads supported by lintels are evaluated in light of the arching action of masonry.
This course includes a multiple choice quiz at the end.
At the conclusion of this course, the student will:
Course IntroductionLintels are beams that support masonry above openings in walls. Typically lintels for concrete masonry walls are constructed of either masonry bond beams or precast concrete beams. Masonry bond beams are constructed of unit masonry blocks in the field. These types of lintels require that shoring first be erected to support the bond beam elements during construction until the masonry and grout achieves the necessary strength. Precast concrete lintels are typically fabricated offsite and shipped to the job site for erection. In either case, bond beam and precast lintels have the advantage over steel lintels in that they do not have to be fireproofed for load bearing walls and can typically be installed by the same contractor responsible for the construction of the wall.

The design of masonry and concrete lintels requires an understanding of the load path mechanisms of unit masonry walls. The natural arching action of running bond masonry walls often provides an alternate load path for both uniform and concentrated loads located above a lintel. Concrete masonry lintels are most often designed using the allowable stress design or service stress method of analysis. The design precast concrete lintels must comply with the ultimate strength design provision of ACI 318.
