概要 A structural system using a coupled reinforced concrete (RC) U-shaped core wall, which carries the majority of
seismic lateral forces, improves the design flexibility of super-high-rise RC condominium. This experimental
study is composed of two test series using the design strength of 60 MPa concrete. The first test is 'lateral
loading test' of three 1/10-scale RC core walls, which evaluates the influence of the horizontal loading angle (0,
45, 90 degrees) on the wall capacity design. The second one is 'uni-axial loading test' of extracted core wall
elements (i.e. corner, web and edge), which assesses the axial compressive capacity of confined and
non-confined concrete. By means of the moment-curvature biaxial analysis with the fiber model, considering the
confined concrete characteristics, confined region and the hinge length, it was possible to evaluate the flexural
deformation component of the lateral loading test results.
