However reading the above commentary section r22 5 1 7 you can use the provisions of chapter 23 to design using the strut and tie model.
Pipe sleeves for concrete beams.
Modular seal links create a positive seal both inwards and outwards to effective pressure sealing for pipes through concrete walls.
Looking in aci 318 14 building code requirements for structural concrete i find the following.
Pipes through or under footings or foundation walls.
Any pipe that passes under a footing or through a foundation wall shall be provided with a relieving arch or a pipe sleeve pipe shall be built into the foundation wall.
The placement of conduits pipes and their fittings embedded within reinforced concrete columns are permitted provided that total embedment area is not greater than 4 of total concrete cross section used.
For over 50 years crete sleeve has been producing the highest quality plastic hole forms for the construction industry.
The sleeves offered in pvc and galvanized steel include a 2 water stop to provide both stability and protection against moisture penetrating the wall.
To make the sleeves automatically adjust and stay matching the pipe size assign it to the pipe fitting category with multiport sub category.
The tests studied the effect of installation of pvc pipe on behavior of reinforced concrete moderate deep beams.
I recommend adding a boolean parameter in the family to override the sleeve id and od in case you need to deviate from the automatic sleeve size.
The test parameters were the diameters and locations of the pipes.
Modular link seals for large diameter pipes annular seals wa ls gkd modular links seal pipe penetrations.
One beam was constructed without pipe as control and the remaining five had embedded pipes.
Steel concrete cast iron hdpe pvc pipes and all pipe sizes.
The dimensions of beams were 1000 mm length 150 mm width and 300mm depth.
Any changes to the pipe size will also change the sleeve size.
From section 305 5 in the 2006 ipc p2603 5 in the 2006 irc.
Doing a word search for opening only shows specific results for openings in one way and two way slabs and walls.
