Masonry arching action

[Subject Prev][Subject Next][Thread Prev][Thread Next]
Title: Message
What are some guidelines for considering masonry arching over an opening? I am looking at some loadbearing walls with standard doors, small windows, and a double door in it.  How far can masonry arch? Does the spacing of the bar joist affect the width of arching action? Do you need a lintel to span over closely spaced standard doors? There is 4' of 8" CMU overtop of the doors and windows. I am wondering how far the masonry can arch before it I have to start designing my lintels for the weight of the floor or roof.
