I am designing repairs for a 6 ft tall stone retaining wall about 120 feet long that is pitching over. The plan is to stabilize with a series of masonry buttresses. Normally I size buttresses based on their mass to resist overturning moment. Wondering if I can reduce their size by designing them...
I have been hired to repair the party wall of a 100 year old brick mass one story commercial building that was damaged due to underpinning construction below the stone footing. Damage is at the front corner and appears to be due to vibration from the underpinning; not footing movement. The...
