| Popis: | 97 Most of building structures in Taiwan are designed as moment-resisting reinforced concrete structures. Engineers do generally not consider the existence of the lightly reinforced “nonstructural walls” in design stage. In this research, a total of four specimens, including one moment-resisting frame (MF), one moment-resisting frame in-filled RC wall(MFW), and two moment-resisting frames with three-side semi-slitted RC walls(AI6 & AI4) were constructed and tested cyclically. The purpose of three-side semi-slits is to reduce the structural effect of nonstructural walls to frames. Test results shows that：(1) MF has a good ductility development under cyclic loading, and after reach the maximum strength it has no significant degradation；(2) The maximum strength of MFW about 3.0 times higher than MF, and the ductility ratio is 2.5；(3) The maximum strength of AI6 about 2.9 times higher than MF, and the ductility ratio is 1.9. The wall spalled significantly；(4) The maximum strength of AI4 about 1.9 times higher than MF, and ductility ratio was around 5.9；(5) The specimens with wall, the initial stiffness around 4.0 times higher than MF. |
