摘要
采用弹性大变形分析以及塑性分析相结合的方法讨论了循环压缩－拉伸载荷下长矩形板的非弹性载荷－变形性能。重点是探讨循环面内载荷下薄矩形板在后屈曲范围内的滞回特性。分析表明，板的面内压缩刚度和承载能力将随循环次数的增加而不断降低。
By a combination of perfectly elasic large de6Ction analys19andp6Tf6Cdy…8Standy,sis,the inelastic load-deflection behavior of a long rectangular plate under cyclic compressiveand tensile loads is discussed.The emphasis is placed on the hysteretic characteristics of athin rectangular plate subjected to cyclic in-plane loading in the postbuckling range。It hasbeen found from the hysteretic loops of load-deflection curves that the in-plane compressiverigidity and the loading capacity of the plate will deteriorate with an increase of the numberof cycles。
