Abstract

This study conducted nonlinear finite element analysis to figure out the influence of shear performance on the ${\beta}$ of girders with trapezoidal corrugated web. Through the experiment specimen, analysis model which is highly accurate was verified. Based on this, a parameter analysis was conducted on key variables affecting ${\beta}$. Proposed formulas of previous studies were analyzed using parameter analysis result. Eurocode was designed to be safer than other proposals. Only models that are included in the inelastic area, depending on the Moon's proposal, were satisfied the proposed formulas by Kim to enhance economic design.

본 연구는 비선형 유한 요소 해석을 통해 제형의 절곡형상 웨브를 갖는 보의 수평패널 길이와 경사패널의 비 ${\beta}$에 따른 전단 거동을 파악하였다. 선행 실험연구 결과를 통해 정확도 높은 해석모델을 검증하였으며, 이를 토대로 ${\beta}$ 및 전단거동에 영향을 미치는 핵심 변수에 대한 변수해석을 실시하였다. 또한 변수해석 결과를 통해 선행연구의 제안식을 평가하였다. 분석결과 Eurocode는 다른 제안식보다 보수적으로 평가하고 있으며, 김영숙의 제안식은 Moon의 제안식에 따라 비탄성 영역에 포함 된 모델만이 경제적인 평가를 하는 것으로 판단된다.
