Adding connections from the base of the wood-framed structure to the foundation is almost always an important part of a seismic retrofit. Bracing the cripple-walls to resist side-to-side forces is essential in houses with cripple walls; bracing is usually done with plywood. Oriented strand board (OSB) does not perform as consistently as plywood ...
In an earthquake, a lack of grip between a house and its foundation can cause the home to be shoved off — as if the shaking has broken the building's knees.
Crinkle crankle wall in Bramfield, Suffolk. A crinkle crankle wall, also known as a crinkum crankum, sinusoidal, serpentine, ribbon or wavy wall, is an unusual type of structural or garden wall built in a serpentine shape with alternating curves, originally used in Ancient Egypt, but also typically found in Suffolk in England.
Partial soft story collapse due to inadequate shear strength at ground level during the Loma Prieta earthquake.. A soft story building is a multi-story building in which one or more floors have windows, wide doors, large unobstructed commercial spaces, or other openings in places where a shear wall would normally be required for stability as a matter of earthquake engineering design.
For example, the behavior of underground walls has been evaluated for the Northridge earthquake using numerical methods. The comparison of the seismic behavior of underground braced walls with ACI 318 design method reveals that bending moment and shear force of the walls under Northridge earthquake loads were observed to reach 2.8 and 2.7 times ...
Sustainable refurbishment describes working on existing buildings to improve their environmental performance using sustainable methods and materials. A refurbishment or retrofit is defined as: "any work to a building over and above maintenance to change its capacity, function or performance' in other words, any intervention to adjust, reuse, or upgrade a building to suit new conditions or ...
cripple stud – a stud located either above or below a framed opening, that does not run the full height of the wall; post or column − a doubled or other integral multiple of a group of studs nailed side by side. Posts in walls are used at point loads such as long spans near a wide window or sliding door, etc.
A pony wall is a short wall.. In different circumstances, it may refer to: a half wall that only extends partway from floor to ceiling, without supporting anything.; a stem wall, a concrete wall that extends from the foundation slab to the cripple wall or floor joists.
