摘　　要：通过对以往钢板剪力墙资料的研究,提出一种将两片折板对接的蜂窝形截面钢板剪力墙,并对其进行了有限元弹性屈曲分析。通过改变截面几何形状,来改善薄钢板剪力墙的出平面弹性失稳问题,这样就可以更好的发挥钢板材料的强度和延性。研究结论为这种新型钢板剪力墙的研究奠定了基础,并对实际工程中钢板剪力墙的设计与应用提出建议,具有很好的经济和社会效益。Through the study of steel plate shear walls ,a honeycomb section steel plate shear wall composed of two folded plates was proposed here and studied by using the finite element method .By changing the section geometry ,the out-plane elastic instability of thin steel plate shear wall was improved ,so as to play a better role in the strength and ductility of steel materials .The topic as such would lay the foundation for the research on the new-typed steel plate shear walls , and provide some references for the design and application of the steel plate shear walls in practical engineering ,thus having good economic and social benefits .
