| Research Abstract |
The main conclusions of this study are as follows; (a) The proposed SRC system, 'steel' - 'concrete' - 'hoop reinforcement' composite has quite good aseismic performance. (b) Flexural cracks concentrated at the critical sections in the proposed SRC members subjected to bending-shear cracks, and flexural-shear cracks were not observed. (c) Hoop reinforcement improved the compressive behaviour of the concrete and protected the steel from local buckling. (d) Hoop reinforcement contributed to the ductility of members under various loading conditions. (e) Deformation of the SRC member under compression is due not only to compressive strain but also to slip along the inclined crack, and affected by the existance of the H-shaped steel itself. The relation between compressive force and deformation of SRC cannot be evaluated as the sum of those of concrete and steel. (f) The maximun moment carried at the critical sections of members under bending-shear were greater than those under bending. Compressive stress - strain relationship of concrete in the members under bending-shear should be affected by the restraint of thr neighbouring solid concrete.
