| 摘 要： | 为了研究工程用水泥基增强复合材料（ECC）双钢板-混凝土组合剪力墙的抗震性能，建立3片双钢板-混凝土组合剪力墙和12片不同ECC高度下的ECC双钢板-混凝土组合剪力墙数值模拟模型。通过对比不同剪跨比的ECC双钢板-混凝土组合剪力墙抗震性能，确定该组合剪力墙的最适ECC高度。结果表明：对比普通双钢板组合剪力墙，ECC双钢板-混凝土组合剪力墙的峰值荷载和屈服荷载均有所提升。ECC的加入大幅提升了整个结构的延性和耗能能力，中高剪跨比时，ECC对刚度退化影响不大。剪跨比为1.0时，ECC最佳高度取36 mm。剪跨比为1.5时，ECC最佳高度取180 mm。剪跨比为2.0时，ECC最佳高度取72 mm，双钢板-混凝土组合剪力墙抗震性能最好。

| 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. |
