multistory multispan frame

Its' aim is to find the multistory multispan frame structure's plastic limit load (using stiffness increment variation method),and the plastic limit state of stress(or internal force) distribution and the formation of collapse mechanism.
該方法以尋找多層多跨框架結(jié)搆的塑性極限荷載(採用增量變剛度法求解)、塑性極限狀態(tài)時的應(yīng)力(或內(nèi)力)分佈和所形成的破壞機搆爲(wèi)目的。
