چکیده

دیوار برشی فولادی یکی از انواع سیستم های بار بر جانبی می باشد که استفاده از آن در صنعت ساختمان رو به گسترش است. عملکرد مناسب دیوار برشی فولادی که بر اساس گسترش میدان کششی می باشد، تا حد زیادی وابسته به المان های مرزی شامل تیر ها و ستون ها می باشد. بعبارت در فرایند استهلاک انرژی طی تسلیم ورق نازک جان نیروهای قابل ملاحظه ای به المان های مرزی وارد می گیرد. از این رو برای آنکه سازه مجهز به سیستم دیوار برشی فولادی از عملکرد مناسبی برخوردارباشند می بایست المان های مرزی علی الخصوص ستون ها دارای رفتار الاستیک باشند. در این مقاله برای کنترل رفتار الاستیک ستون ها استفاده از ستون های دارای مقاطع قوطی‌شکل فولادی پرشده با بتن بعنوان المان مرزی و نیز پانل‌های حلقه‌شکل بعنوان ورق جان پیشنهاد شده است. به منظور کنترل رفتار الاستیک ستون، بیرون کشیدگی بال مجاور ورق پرکننده مورد بررسی قرار گرفته شده است. مشاهده می شود که استفاده از ورق های حلقه ای شکل اثر قابل ملاحظه ای در کاهش بیرون کشیدگی بال ستون دارند . بعبارت دیگر استفاده از ورق های حلقه دار می تواند از تسلیم المان های مرزی قائم جلوگیری کند.

چکیده [English]

Steel shear is one of the many types of side loading systems that is being used in the building industry. The proper performance of the steel shear wall, which is based on the expansion of the tensile field, is largely dependent on the boundary elements including beams and columns. In other words, in the process of energy depreciation, during the surrender of a thin sheet of paper, considerable forces will enter the boundary elements. Therefore, in order to have a well-functioning steel shear system structure, the boundary elements, especially the pillars, must have elastic behavior. In this paper, for the control of the elastic behavior of the columns, the use of columns with steel canisters filled with concrete as a boundary element, as well as roller panels, is proposed as a die sheet. In order to control the elastic behavior of the column, the outflow of the adjacent wing of the filler sheet has been investigated. It can be seen that the use of loop-shaped sheets has a significant effect on the reduction of pillar elongation.
