reentrant corner
Isaac Kremer/ January 14, 2018/ / 0 comments
The plan configuration of a structure and its lateral force-resisting system having projections beyond a corner significantly greater than the plan dimensions in the given direction. A reentrant corner tends to produce differential motions between different portions of the structure, resulting in local stress concentrations at the corner. Solutions include providing a seismic joint to separate the building into simpler shapes, tying the building together more strongly at the corner, or splaying the corner. (Ching, 1995)
