인하도선으로 활용하기 위한 철근콘크리트구조물의 전기 및 기계적 소요 특성에 대한 실험적 검증

Abstract

This paper verified the characteristics of electrical continuity and mechanical strength of steelwork required to use it as a down-conductor in lightning protection system. It was proven that the steelwork in reinforced concrete apartment has an excellent electrical continuity with low resistance(less than 0.2[Ω].). But it was confirmed that a poor connection between two reinforcement bars can easily cause serious damages of the concrete even with the impulsive current of 50[㎄], 10/350[㎲]. These results of experiments mean that the additional measures are necessary in using the steelwork as the down-conductor of the lightning protection system.
