The Design of Initial Member Sections and the Evaluation of Seismic Performance for Architectural Steel Structures with Brace Hysteretic Dampers

내진 댐퍼 브레이스를 가진 건축 강구조물의 초기 분재단면 설계 및 내진성능 평가

An initial member sections of steel structures is selected by experience of expert building structural designers. And appropriate member section is designed by repeat calculation through structural analysis. Therefore an initial assumption of member section is necessary for saving the time for structural design and is important to acquire safety of building structures. Also brace damper are generally used to prevent or decrease structural damage by its hysteretic behavior in building structures subjected to strong earthquake. Based on plastic design, the initial section of members for architectural steel structures with brace hysteretic dampers is presented and seismic effect of structural behavior by the ratio of damper stiffness to structural story stiffness is estimated in this paper.
