In structural engineering, a diaphragm is a structural element that transmits lateral loads to the vertical resisting elements of a structure (such as shear walls or frames). Diaphragms are typically horizontal, but can be sloped such as in a gable roof on a wood structure or concrete ramp in a parking garage. The diaphragm forces tend to be transferred to the vertical resisting elements primarily through in-plane shear stress. The most common lateral loads to be resisted are those resulting from wind and earthquake actions, but other lateral loads such as lateral earth pressure or hydrostatic pressure can also be resisted by diaphragm action.
和剪力墙相对应的是隔膜板,或者横隔板,通常是水平的。横隔板是为保持截面形状、增强横向刚度而在梁之间设置的构件”。它对桥梁上分布的活荷载起作用。现浇混凝土横隔板通常用于预制预应力混凝土T型梁。位于桥梁端部的横隔板称为端隔板,位于中部的横隔板称为中隔板。
diaphragm action可以翻译为隔板作用,或者横隔板作用。
具体的语境会导致diaphragm action存在一定的偏差,请自己调整。 |
