Hold down (structural engineering) : ウィキペディア英語版 | Hold down (structural engineering)
Holdown (hold-down, hold down) or tie-down in structural engineering refers to the steel device or hardware that is installed at the end of a plywood shear wall. The holdowns provide uplift resistance against the overturning moment imposed on the wall due to "in-plane" lateral load applied at the top of the wall. A hold-down may also refer to clamping device used to anchor a pipe to a structural steel element or concrete floor or allow movement of the pipe in an axial direction.〔(Hold-Down Pipe Clamps ) Piping Technology and Products, (retrieved May 2012)〕 At the bottom, the holdown is connected to the concrete foundation or structural slab by an ''embedded'' or ''epoxied'' anchor bolt. At the top, the holdown is connected to a wood post with screws, nails or bolts. ==References==
