The mechanical impedance is a measure of resistance that an element, system or a construction provides to the motion when it is under the influence of a certain force. It is defined as the ratio of force and speed at a certain point in a system. By measuring the mechanical impedance important informations are obtained about the dynamic behavior and response of a system or structure exposed to vibratory force which which is a significant factor in modern day civil engineering. Increasing complexity of constructions increases the need for new types of concrete as a basic construction material, which still dominates the global construction industry. Fiber reinforced high performance concrete is a new type of concrete characteristic with high compressive strength, and with the addition of fibers that improve ductility at tensile load. Such concrete appeared about twenty years ago, therefore it can be said that it is still a relatively young type of concrete and yet need to find its application in the construction industry. This paper describes the equipment, set-up and results of the tests to determine the mechanical impedance of fiber reinforced high performance concrete samples in order to study the mechanical behavior and response of samples subjected to vibration of different frequencies.
