Preloaded bolt analysis

WebAug 27, 2016 · Bolts are tightened such that a high tension, usually above yield strength, is developed in the bolts, these are called preloaded bolts. The plates of the connection are thus clamped together and shear transfer between the plates is achieved through friction. Preload is the tension load developed in a fastener while tightening.
