| dc.description.abstract | Fiber reinforced concrete have for long been researched to better find its possibilities
withing concrete structures. Today fibre reinforced concrete is mainly used for slabs
resting on the ground, or as thin shotcrete. In some cases the fibre replaces the
traditional reinforcement completely, and can reduce costs on project considerably.
With further investigation fibre reinforced concrete could possible replace traditional
reinforcement partial, while improve its mechanical behavior and durability. Bridge
piers are exposed to many different accidental loads, such as vehicle impacts,
explosions, and barge collision. The bridge structure must be designed to handle
this types of load, and its impact response is an essential part of understating the
forces acting on the pie.
In order to determine the piers response, scaled down laboratory experiment are
performed, as building a full scale is inefficient. Pendulum test were performed on
three 100x100x1500mm concrete column, with a fiber dosage of 0.0%, 0.5% and
1.0%. The results from the impact test together with the mechanical properties
of the basalt fibre reinforced concrete were used to develop a numerical model, to
simulate the laboratory test. The accuracy of the model is determined by comparing
the experimental results with the numerical results. | |
