Abstract

PADO. A computer code for design optimization of steel portal frames S. Hernindez, P. Loscos, A. N. Fontin & J. C. Perezzhn School of Civil Engineering, University of Coruiia, Spain. Abstract A computer code aimed to produce optimum design of portal fiames is presented in this paper. The PAD0 software provides the least weight design for the most common types of planar frames. The code incorporates the complete set of constraints considered in the spanish code of practice for steel structures. The software has a graphical interface to provide a user friendly communication. Some application examples are presented in this paper to make clear the capabilities of PAD0 code. 1 Introduction Optimum design of internal dimensions of metal structures has been considered by several researchers since many years ago. Sometimes thls problem is one level in a multilevel optimization of complex structural systems 11-21, Other contributions were pointed out in [3-41. Lately, a lot of emphasis has been put i
