Method for designing dynamic coefficient of exponential explosion load resistance of damping-containing rigid structure

The invention relates to a method for designing a dynamic coefficient of an exponential explosion load resistance of a damping-containing rigid structure, and belongs to the technical field of anti-explosion design. The specific rigid structure refers to that under the action of an exponential type explosion load, the moment tT corresponding to the maximum elastic vibration displacement yT of thestructure to enter plastic vibration is smaller than the numerical value of the real action duration ti of the explosion load; and after the explosion load is unloaded, the structure continues to vibrate to a certain moment tm, and the total maximum elastic-plastic displacement value ym of the structure is achieved; according to the action process of explosion on a building structure, the processis divided into three stages of elastic-stage forced vibration, plastic-stage forced vibration and plastic-stage free vibration; through calculation of the different stages, accurate description of the structure type and expon
