摘 要:通过三向应力状态下的不同钢纤维含量的混凝土动态特性试验研究发现,随着围压的增大,各种掺量钢纤维混凝土的峰值应力显著提高。同一种围压条件下,随着钢纤维掺量的增大,钢纤维混凝土的峰值应力提高不多。同时建立了钢纤维混凝土动态本构关系及失效准则。
Abstract: Under the condition of three-dimensional stress state, the concrete dynamic characteristic test with different content of steel fiber is studied. The study result show that with the increasing of confining pressure, the peak stress of steel fiber reinforced concrete are significantly increased. But under the same kind of confining pressure, with the increasing of the steel fiber content, the peak stress of steel fiber reinforced concrete is not obviously improved. In addition, the dynamic constitutive relation and failure criteria for steel fiber reinforced concrete are established.
