MASONRY WALL ARCHING ACTION The typical door and window openings in masonry walls are bridged over by horizontal members spanning from opening jamb to jamb by lintels which are essentially beams. In many cases the loads to be applied to the York Building Products precast lintels may be calculated with consideration of masonry walls load “arching” behavior. Through the “arching” behavior some loads may be considered to distribute to either side of the opening and not need to be resisted by the precast lintel. The wall surrounding the opening must meet several criterion in order to consider arching action to be occurring. These criterions are: 1. 2. 5. 6. The masonry wall is laid in a running bond pattern. At the time that all of loads that are to be supported by the lintel are applied, the masonry wall must be in a completed condition and cured to full wall material strength. Minimum end bearing of at least 4 inches. There is sufficient masonry wall on either side of the wall opening to resist the horizontal thrust induced by the arching action. Control joints, expansion joints or other discontinuities are not located at or adjacent to the opening. There is sufficient wall height above the top of the lintel to a include a 45 degree triangular “arching” zone. 7. The wall height above the apex of the triangular zone is at least 8 inches. 3. 4. If these criterions are met, arching action may be considered in lintel sizing and selection. -4-
MASONRY WALL ARCHING ACTION The types of load patterns that are typically supported by lintels are, uniform, concentrated , partial uniform and triangular as indicated in the below diagram. If arching action is in effect the final loads to be supported by the lintel include: The self weight of the lintel, The weight of the masonry wall within the triangular zone. Concentrated load within the triangular zone. Other load types either dead or live load floor and roof loads above the triangular arching zone may be considered to “arch” and distribute the load to each side over the wall opening. -5-

The composite design means the lintel is very stable during installation, allowing it to be installed in the same way as a standard steel lintel with no propping required. Lintel design has been completed in line with EN 845-2. Structural Testing was carried out by the University of South Wales following EN 846-9. The University of South Wales is a
