钢纤维混凝土大量应用于军事防护工程以防御高速侵彻和爆炸冲击,钢纤维-钢筋混凝土结构在低速冲击作用下的性能表现是目前反恐安全和交通安全领域的重点研究对象,为此设计制作了两种配筋率下的钢纤维-钢筋混凝土板,用落锤试验仪模拟低速动荷载对试件抗冲击性能的影响,通过掺加不同比例的钢纤维,比对分析对低速冲击破坏形态和荷载、位移和能量变化规律,得出钢纤维掺量对钢纤维-钢筋混凝土板抗低速冲击性能的影响。
A large number of steel fiber reinforced concrete used in military protection projects to prevent high-speed penetration and explosion impact, steel fiber - reinforced concrete structures under low-speed impact performance is the current counter-terrorism and traffic safety in the field of key research object, designed for this The effect of low speed dynamic load on the impact resistance of the steel fiber reinforced concrete slab under two kinds of reinforcement ratio was simulated by using a falling weight tester. By adding different proportions of steel fiber, Load, displacement and energy variation of the steel fiber content of steel fiber - reinforced concrete slab impact resistance to low-speed impact.
