Masonry
(OP)
I am designing a cavity masonry wall that is supported on two separate 5m span lintels. The inner leaf lintel is also connected to steel posts and is acting as a wind portal. I am worried about the horizontal movement between the two leaves of blockwork and the effect it will have on the strength of the wall ties. Does anybody have any experience on the subject? Am I allowed to have two leaves moving relative to one another laterally?






RE: Masonry
wind or seismic?
How much lateral deflection is allowed by your masonry ties?
Can you tie the outer beam to the portal frame so both beams will be moving somewhat equally?

Consider one beam with a wide plate to support the masonry wall. Of course, I don't know the particulars on whether this is possible. This would, however, help alleviate your problem. Consider your beam's vertical dead load deflection and connection welding procedure (if welded moment connection).
