In recent years, man-made or accidental explosions occur frequently, to people's lives and property poses a serious threat. Also, due to the important buildings worldwide more, therefore, how to minimize damage to the building structure blast loading, reducing its threat to people's lives and property safety, becoming a need to solve the issue.
    Improve the performance of building materials to improve the building structure antiknock performance, lower effective means of explosions on people's lives and property safety hazard. Ultra High Performance Concrete (hereinafter referred to as UHPC) is a cement-based construction materials in the past three decades a very innovative, ultra-high performance concrete strength, excellent toughness and good durability. Therefore, the UHPC used in building structures Blast-proof design is a useful attempt. Many scholars conducted exploratory research, such as testing and other research 焦楚杰 by the explosion of steel fiber content of 1% to 3% of its UHPC board antiknock performance, research shows that the explosion showed significant attenuation of stress waves in concrete features, its advantages in terms of seismic collapse is very obvious. 卢康 Road by explosion testing to determine the optimal dosage of steel fiber steel fiber reinforced concrete under blast loads in for the engineering application of steel fiber reinforced concrete provides a theoretical support. Numerical analysis method using the literature of different steel fiber concrete panels and ordinary concrete slab under blast loading of dynamic response and failure mode of the study showed that the extent of damage of steel fiber reinforced concrete panels is much smaller than the extent of damage to ordinary concrete slab .
    In this paper, an explicit dynamic finite element analysis software LS-DYNA on a typical ultra-high performance reinforced concrete columns and reinforced concrete columns under the same dynamic response to blast loads were simulated by comparative analysis to study the ultra-high performance steel antiknock performance concrete columns to clarify the ultra-high performance reinforced concrete columns huge advantage in terms of blast-resistant design.
