By using the finite element software ABAQUS we analyse the concrete frame structure with three storeys and three spans

and study the impact location

the impact mass

the initial impact velocity and the influence on the dynamic response of frame structure.The results show that the initial impact velocity has significant influence on the impact force peak

while the impact position has little influence on the impact force peak.The initial impact velocity has great influence on maximum deflection and ultimate deflection of beam

while the impact position and the impact mass have little influence;when the side-span beams are impacted

the adjacent beam-column joints suffer serious tensile damage

while when the mid-span beams in the same storey are impacted

the tensile damage in entire frame beam-column joints are relatively slight

but the distribution are relatively wide.With the increase of the impact mass and the initial impact velocity

storey the tensile damage of the whole frame structure is more and more serious

frame beams and beam-column joints are the main energy-consuming locations.
