Performance Index Of Steel Structure - Knowledge
The strength index of steel is composed of elastic limit ge,yield limit oy,and tensile limit ou.The design is based on the yield strength of steel structural parts.The high yield strength can reduce the weight of the structure,save steel,and reduce the cost.The tensile strength ou is the maximum stress that the steel can withstand before failure.At this time,the structure loses its performance due to large plastic deformation,but the structure is large without collapse,meeting the requirements of the structure to resist rare earthquakes.The value of 'ou/oy can be regarded as a parameter of steel strength reserve.
