چکیده مقاله :
دیوار برشی فولادی، سیستم مقاوم در برابر بارهای جانبی است که در دهه‌های اخیر مورد توجه قرار گرفته است. دیوارهای برشی فولادی به دو صورت دیوارهای سخت‌شده و سخت نشده کاربرد دارند. هرچند رفتار پس کمانشی دیوار برشی فولادی باعث باربری پس از کمانش می‌شود، اما همواره این کمانش ورق مطلوب نیست. یکی از راه‌حل‌های مفید جهت از بین بردن کمانش جانبی، استفاده از دیوارهای با ورق موجدار است. در این تحقیق رفتار دیوار برشی فولاد متشکل از دو ورق تخت و یک ورق موجدار در دو حالت فولاد معمولی (A36) و فولادی با حد تسلیم پایین(LYP) مطالعه شد. استفاده از فولاد با حد تسلیم پایین، عملکرد لرزه‌ای سیستم دیوار برشی فولادی را بهبود بخشید. با در نظر گرفتن تغییرات ضخامت ورق‌ها و نسبت ابعادی‌های مختلف، فولاد LYP، مقادیر سختی، مقاومت و جذب انرژی را حدود 74%، 51% و 36% افزایش داد. میزان تاثیر افزایش ضخامت ورق در پارامتر سختی برای پانل برشی با فولاد A36 بیشتر از فولاد LYP است. افزایش ضخامت ورق‌ها، سختی، مقاومت نهایی و جذب انرژی سیستم را برای فولاد A36 به ترتیب حدود 45%، 35% و 44% و برای فولاد LYP حدود35%، 62% و 53% افزایش داد و همنین افزایش نسبت ابعادی سختی، مقاومت و جذب انرژی سیستم را برای فولاد A36 به ترتیب 51%، 36% و 38% و برای فولاد LYP به ترتیب 52%، 46% و 49% افزایش داد.
The steel shear wall is a lateral load resistant system that has received attention in recent decades. Steel shear walls are used in two ways: hardened and unhardened walls. Although the post-buckling behavior of the steel shear wall causes the post-buckling loading but this plate buckling is not always desirable. One of the useful solutions to prevent lateral buckling is the use of walls with corrugated plates. In this research, the behavior of a steel shear walls consisting of two flat plates and one corrugated plate was studied in two states of conventional structural steel (A36) and low yield point steel(LYP). The use of low yield strength steel improved the seismic performance of the steel shear wall system. Taking into account the changes in the thickness of the plate and different aspect ratio, LYP steel increased the values of stiffness, ultimate strength, and energy absorption by about 74%, 51% and 36%. The effect of increasing the plate thickness on the stiffness parameter for infill panel with A36 steel is more than that of LYP steel. Increasing the thickness of the plates increased the stiffness, ultimate strength, and energy absorption of the system for A36 steel by about 45%, 35%, and 44%, and for LYP steel by about 35%, 62%, and 53%, and also increase in the dimensional ratio of stiffness, strength and increased the energy absorption of the system for A36 steel by 51%, 36% and 38% respectively and for LYP steel by 52%, 46% and 49% respectively.
