A Method for Large Deflection Inelastic Analysis of Plate Grillages under Normal and Axial Loads,

摘要

A method for analyzing plate grillages subjected to normal and axial loads was developed. Elasto-plastic range and large deformations are considered. The grillage equations were formulated from the general differential equations of plates and beams and a collocation type approach was employed for solving these equations. Due to the geometrical and material non-linearity of the problem it was necessary to employ a search technique in arriving at an answer. The feasibility of the method was demonstrated by analyzing a rectangular plate and a plate grillage with two transverse and two longitudinal stiffening beams. (Author)
