Ultimate Strength Study Of Aluminium Members And Plates Considering Local Buckling

As a new-style structural material, aluminium alloy has the characteristic of lightweight, uncorruptness, convenient for maintenance and assembly, and fits need of development of modern engineering structures to long-span, lightweight and high-durability. The study for aluminium alloy structure already began in China, and the concerned design code is being established now. Those researches will boost the application of aluminium alloy structure in China.Supporting by projects of and , the paper studies thin walled aluminium alloy members under axial force, aluminium alloy girders under shear, and the resistance of aluminium alloy plates.The paper presents the theory analysis for thin walled aluminium alloy members under axial force and aluminium alloy girders under shear. Based on experimental data, the finite element models were established and confirmed. Based on parameter analysis, a series of design formulas were proposed. Moreover, The paper presents the whole design method and design formulas for aluminium alloy plates. Based on experimental research, those design formulas were confirmed. The main productions of this paper can be found in the following list:1) The direct strength method is introduced for calculating the resistance of thin walled aluminium alloy members under axial force. It will solve the disadvantages of the effective section theory.2) Ansys software was adopted to do the non-linear analysis of thin walled aluminium alloy members under axial force. The calculation results of finite element model have been verified by comparison with experimental results. The accurate data was provided by the finte element analysis for the parameter analysis later.3) The design formulas based on direct strength method were proposed for calculating the resistance of thin walled aluminum alloy members under axial force, and were verified by comparison with experimental results, finite element results and...
