摘要：This research aims to study the effect of UHMWPE fiber content on the blast resistance of concrete slabs. A 3D fluid-solid coupling model was established by numerical simulation method to simulate UHMWPE fiber reinforced concrete slab under close-in detonation. It turns out that the simulation results show the damage behavior of reinforced concrete slabs greatly. UHMWPE fibers can effectively reduce the local damage of the slab and improve the overall blast resistance. When the UHMWPE fiber content is less than 0.5%, the performance of blast resistance increases with the content. When the fiber content exceeds 0.5%, the effect of blast resistance caused by fibers is limited.
