1 * EN 1990 BRIEF INTRODUCTION TO STRUCTURAL DESIGN WITH EUROCODES Shen Jianming Wang Junping Li Mengxiong Department of Civil EngineeringFaculty of Civil Engineering and ArchitectureKunming University of Science and Technology Kunming China Abstract In this paperit is briefly introduced the scheduling system and characteristics of Eurocodesand briefly described the basis of structural designsuch as design situationdesign working lifeconsequences classesultimate limit state and so on. It is focused on the similarities and differences between Eurocodes and Chinese codes in the partial factor method.
