Power plant steel pile foundation steel bar steel pole power power pole

Steel rods to stabilize the security of the center under pressure: Due to the high strength steel bar Jing material, steel rod center bar by the time the case of a flexible rod member constant, bearing steel rods cut power often depends on the stability of the critical force. Stability safety factor used for the world differently. China's current steel rod used is still considered by the Soviet Union norms critical stress value, when changing the oil-service method of static content static stress method to limit state method, safety factor and stable change. Thus creating the appropriateness of Jane safety problems. This simple question some superficial analysis, personal meaning brother. First, the world center of the selection pressure on the stability safety factor of compressed flexible center pole Hu Lin pole critical stress depends on the name of Euler's formula: E Ting top of the gas p = * (1 but inelastic stage,? Lang when the critical stress', is greater than the proportional limit and less than the current limit "Two, the formula will not apply.
