CALCULATION OF REDUCED GEOMETRIC CHARACTERISTICS OF LIGHTWEIGHT THIN-WALLED STEEL STRUCTURES USING AUTOMATED SPREADSHEET ANALYSIS
Abstract and keywords
Abstract:
This paper examines the theory and practical methods for the design of lightweight steel thin-walled frame structures, taking into account the reduction in cross-sectional area due to the occurrence of local zones of instability. The authors have reviewed the technical and scientific literature on the design of thin-walled steel structures, taking into account section reduction. Methods for calculating such structures have been selected, corresponding to their actual behavior under the action of loads. The authors have developed and tested engineering methods for calculating the reduced geometric characteristics of thin-walled steel members in accordance with current design standards, utilising spreadsheet software functionality. The paper presents practical results of calculating the geometric characteristics of reduced cross-sections using the developed algorithm, in comparison with other software environments for calculating characteristics sections of structures.
