| از صفحات فلزی فولادی و آلومینیومی به صورت گسترده در ساخت سازه‌های جدار نازک در شاخه‌های مختلف مهندسی، به ویژه مهندسی عمران، استفاده می‌شود. تحقیق حاضر با استفاده از روش المان محدود تاثیر وقوع کمانش و تسلیم را در خصوصیات رفتار خطی/غیرخطی و قابلیت جذب انرژی صفحات برشی فلزی با نسبت‌های لاغری مختلف مورد مطالعه قرار می‌دهد. دو نوع مصالح کاربردی فولادی، شامل فولاد کربن‌دار و فولاد با تنش تسلیم پایین، و یک نوع آلیاژ آلومینیوم برای صفحات فرض می‌شود. از نتایج تحلیل‌های استاتیکی غیرخطی به منظور: - تقسیم‌بندی صفحات در پنج محدوده رفتاری پیشنهادی (بسیار لاغر، لاغر، متوسط، ضخیم، بسیار ضخیم)، - ارائه روابط ریاضی جهت مرزبندی و تخمین بار کمانشی، و - تشریح خصوصیات صفحات هر محدوده رفتاری در ارتباط با منحنی‌های رفتار، نحوه توسعه تنش‌ها و دامنه‌های رفتار خطی/غیرخطی در طول بارگذاری استفاده می‌شود. نتایج تحلیل‌های چرخه‌ای نیز نشان می‌دهد که قابلیت جذب انرژی صفحات در محدوده‌های بسیار ضخیم، ضخیم و متوسط، متاثر از تنش تسلیم و مدول الاستسیته اولیه مصالح است، در حالی که در محدوده لاغر، به ویژه برای نسبت‌های لاغری بزرگ‌تر، از تاثیرگذاری پارامتر تنش تسلیم کاسته، و نقش مدول الاستسیته اولیه مصالح پررنگ‌تر می‌شود. در محدوده بسیار لاغر نیز به نظر می‌رسد که مدول‌های الاستسیته اولیه و ثانویه مصالح نقش موثرتری در قابلیت جذب انرژی صفحات داشته باشد. | ||

| چکیده [English] | ||
| The present study investigates the effects of material mechanical properties and slenderness ratios of plates on the nonlinear and cyclic behavior characteristics of metal shear panels (including carbon steel (CS), low yield point steel (LYP160) and aluminum (Al)), using the finite element method. The plates are first qualitatively and quantitatively classified into the five groups of very slender, slender, moderate, stocky and very stocky, regarding their slenderness ratios. Very slender plates have negligible buckling capacity and thus, they buckle at the initial stages of loading. Slender plates buckle in the elastic range of behavior. Moderate plates buckle in the inelastic range of stresses before material yielding occurs in the plates. Stocky plates buckle in the plastic (post-yield) range of stresses. The behavior of very stocky plates is only dominated by the yielding phenomenon and they do not buckle during loading. Based on the statistical analysis of the results, new relationships for the estimation of inelastic and plastic buckling loads are also proposed. The cyclic analysis results show that the energy dissipation capability of very stocky/stocky/moderate plates is solely dependent on the material yield stress and elastic modulus of elasticity, whereas for the slender plates, the effectiveness of material yield stress in the energy dissipation of plates is decreased and the role of the material elastic modulus of elasticity becomes more important. In the case of very slender shear plates, the energy dissipation capability seems to be dependent on the initial and secondary modulus of material only. | ||
