역V형 가새골조 거셋플레이트 접합부의 간극거리가 내진성능에 미치는 영향

Strength, stiffness and ductility of gusset plate connections should be considered in order that special concentrically braced frames have desirable ductile behavior, which is cyclic tension yielding and compression buckling of braces under earthquake strikes. If the clearance distance between brace end and restricted line of gusset plate is properly designed, brace could have greater flexibility on its end. This study using finite element models is conducted to examine the influence of the clearance distance on the ductile and inelastic capacity of inverted v-braced frames.
