SMA 강봉으로 체결된 축방향 인장력을 받는 T-stub 접합부의 거동특성

초록

Superelastic-shape memory alloys (SMAs) that have superelastic capcity and shape-memory capacity, is a new material to improve the energy dissipation capacity without residual deformation. recently, SMAs has been applied to the connection of the buckling structures in the shape of wire or bar. Such energy dissipation capacity of SMA wire and SMA bar are affected sensitive according to change of austenite and martensite temperature, ratio of the shape alloy, diameter of SMA wire and bar. This study was conducted to understand that energy dissipation capacity and to examine the possibility of applying the seismic connections of a T-stub connection fastened by SMA bars under axial tensile loads
