화해를 입은 철근 콘크리트 전단벽체의 실용 잔존내력비 식

다국어 초록 (Multilingual Abstract)

The behavior of concrete structures subject to fire is dependent on many factors. The factors include fire duration time in relation to the level of temperature penetration in concrete and reinforcing bars, the mechanical properties of the steel and concrete, amount of reinforcement, and member geometry among others. Although there are a few sophisticated numerical models which can trace the effects of these important parameters on the residual capacity of fire-damaged reinforced concrete walls, practical predictive formulas are in need for rapid and yet reasonable assessment in practice. The practical formulas are developed in this study for fire-damaged normal strength reinforced concrete shear walls which can approximate the predictions of those sophisticated numerical models. The formulas take into account the effects of exposure time to fire, wall thickness, wall length, reinforcement ratio, and concrete compressive strength. The developed formulas are shown to correlate with the predictions of numerical model in a reasonable agreement.
