| Abstract: | In order to study the seismic performance of Engineered Cementitious Composites (ECC) double steel plate-concrete combined shear wall, a numerical simulation model of 3 double steel plate-concrete combined shear walls and 12 ECC double steel plate-concrete combined shear walls at different ECC heights was established.The best suitable shear height of the combined ECC wall was determined by comparing the shear performance of the ECC double steel plate-concrete combined shear wall with different shear span ratios.The results show that the peak load and yield load of ECC double steel sheet-concrete combined shear wall are improved.The addition of ECC greatly improves the ductility and energy consumption power of the whole structure, but ECC affects little stiffness degradation at moderate to high shear span ratio.At the shear span ratio of 1.0, ECC optimal height was 36 mm.At the shear span ratio of 1.5, the optimal height of ECC was 180 mm.When the shear span ratio is 2.0, the ECC best height of 72 mm, double steel plate-concrete combined shear wall has the best seismic performance. |
