| 摘 要： | 采用 NYL-80 型压力试验机进行抗压试验,用YJ-26型静态电阻应变仪测量各级荷载下对应的横竖向应变,同时观察和记录试件的破坏现象,研究了NiTi形状记忆合金环向预应力混凝土结构的强化现象.结果表明SMA环向预应力混凝土柱与同等条件的普通混凝土柱相比,其极限荷载和抗裂性能都有较大的提高.

| Abstract: | The strengthening of NiTi SMA ring pre-stress concrete structure was mainly studied by testing compressive strength, measuring axial and lateral strain,as well as analyzing its broken phenomena.It shows that NiTi SMA ring pre-stress concrete columns are improved both in crack load and ultimate load as compared with plain concrete columns in the same condition. |
