  18. Based upon virtual displacement method and the updated - lagrangian approach, stiffness matrices for two - dimensional elastic - plastic beam model in large displacement were proposed, in the derivation of which transverse stress was included because it was believed that part of the 2nd order effects of various stresses, which are in equilibrium with each other and with the external loads, will counteract each other and neglecting either part would possibly lead to incorrect results
