12 지진시콘크리트는균열콘크리트상태 1. 지진시콘크리트는압축영역과인장영역이불명확해져서균열콘크리트로 간주한다. 이경우균열발생은대부분앵커가설치된부위를따라서 발생한다 : 앵커홀주위에응력집중현상 (notch effect) 앵커의확장력또는앵커에작용하는하중으로인해콘크리트에응력유발 Source: Prof. Rolf Eligehausen, University of Stuttgart: tests to asses the likelihood of cracks intercepting the position of anchors and anchor holes 12

13 균열발생시앵커성능의변화 2. 앵커주위에균열이발생하게되면응력의비대칭적인분산으로인해하중 전달양상이달라지게된다. 균열면 비균열콘크리트에서의응력분산 균열콘크리트에서의응력분산 균열콘크리트에서사용이가능한앵커만이내진성능을가질수있다. 13

14 Tension Shear Crack width 지진하중은단순한균열상태보다훨씬극한상태 3. 지진작용시앵커는아래의상황에저항할수있어야한다 : 반복하중 (Load cycling) 반복되는균열 (Crack cycling) w/ larger crack width 앵커의내진에대한검증은반드시정해진규정에따라테스트를수행해야한다. 14
