Nakashima and his associates [15,16] reported an experimental study demonstrating the superior hysteretic behavior of shear panels made of LYP steel, and on this basis proposed simple analyti- cal models to simulate the hysteretic behavior of LYP steel shear panels。 The hysteresis curve, low-cycle fatigue, and hysteresis energy properties of LYP steels under high strain were also studied by [19], and the superb mechanical properties of LYP steel compared to those of conventional steel were demonstrated in this study。 The advantages of application of LYP steel in SPSW systems have been partially demon- strated through some experimental studies, e。g。 [22,21,5,6], and numer- ical investigations, e。g。 [4,7,12,14], and the research is still underway in this regard。
Due to the low yield stress of LYP steel, material yielding in LYP steel shear walls may occur before geometrical buckling。 Hence, accurate evaluation of buckling and yielding interaction and behavior of SPSWs can enable the efficient structural and economical design of these systems。 Accordingly, infill plates in SPSWs may be qualitatively and quantitatively classified as slender, moderate, and stocky based on their slenderness parameter as well as geometrical–material bifurcation characteristics [9]。 Slender plates undergo early elastic buckling and subsequently yield in the post-buckling stage。 Moderate plates, on the other hand, undergo simultaneous buckling and yielding, while stocky plates yield first and then undergo post-yield inelastic buckling。 Based on this classification, accurate determination of the limiting plate thick- ness corresponding to concurrent geometrical–material bifurcation can serve as an effective tool in the design of LYP steel shear wall systems with enhanced energy dissipation capacity。
In this paper, the structural performance of code-designed and unstiffened LYP steel shear wall systems is examined primarily through finite element analysis。 The advantages of using LYP steel material in SPSW systems as compared to the conventional steel material  are

demonstrated through comparison studies。 In addition, the perfor- mance of the SPSW models with slender, moderate, and stocky LYP steel infill plates under monotonic and cyclic loads is investigated as well。 Lastly, the effectiveness of a modified plate–frame interaction model, originally developed by [18], in predicting the response of steel shear wall systems with moderate and stocky infill plates is evaluated through comparison with some experimental as well as experimentally- verified numerical results。 未加筋的低屈服点钢板剪力墙的结构性能英文文献和中文翻译(2):http://www.youerw.com/fanyi/lunwen_134775.html
