Abstract: This paper compares the differences of aseismic behaviours between slitted and non-slitted shear walls under horizontal forces. There are 5 specimens for slitted shear walls and another 5 specimens for non-slitted shear walls. The static horizontal forces, uniformly distributed at top of wall, are monotonic, repeated in one direction, reversed in two directions and random cyclic. The comparisons of crack propagation and load-deflection curves under each loading history are discussed for slitted and non-slitted shear walls. The comparisons of energy dissipation at failure stage and deterioration of residual capacity are also discussed in this paper.
