| Zusammenfassung |
The purpose of this research is to collect fundamental data and to establish
a performance-based design method for reinforced concrete beams under
perpendicular impact load.
Series of low speed impact experiments using reinforced concrete beams were
performed varying span length, cross section and main reinforcement.
The experimental results are evaluated focusing on the impact load
characteristics and the impact behaviours of reinforced concrete beams.
Various characteristic values and their relationships are investigated such
as the collision energy, the impact force duration, the energy absorbed by
the beams and the beam response values. Also the bending performance of the
reinforced concrete beams against perpendicular impact is evaluated.
An equation is proposed to estimate the maximum displacement of the beam
based on the collision energy and the static ultimate bending strength. The
validity of the proposed equation is confirmed by comparison with
experimental results obtained by other researchers as well as numerical
results obtained by FEM simulations. The proposed equation allows for a
performance based design of the structure accounting for the actual
deformation due to the expected impact action. |
