大量的试验研究和地震震害表明,在强烈地震作用下,桥梁墩柱的塑性铰区域遭到破坏较多,是由于墩柱的弯曲延性不足而导致。
A large number of experimented researches and earthquake indicate that most damages belong to the areas of plasticity hinge of piers in server earthquake, because piers lack curve ductility.
优点:耐磨性佳、防滑、有弹性、不易断裂、柔软度较好、伸延性好、收缩稳定、硬度佳、弯曲性好。
Advantages: good abrasion resistance, anti slip, elasticity, not easy to break, softness, good stability, extended contraction, good hardness, good bending.
但抗弯曲强度和冲击强度及较高的延性,与金属不相上下。
But the ductility of flexural strength and impact strength and higher, and the metal be roughly the same.
