Abstract
Mehanička impedancija predstavlja mjeru otpora kojeg element, sustav ili konstrukcija pruža gibanju kada se na njega djeluje nekom silom. Definirana je odnosom sile i brzine u istoj točki sustava. Mjerenjem mehaničke impedancije dobiju se važne informacije o dinamičkom ponašanju i odazivu nekog sustava ili konstrukcije na vibracijske sile različitih frekvencija što predstavlja bitan faktor u modernom građevinskom inženjerstvu. Povećanjem složenosti građevinskih zahvata raste i potreba za novim vrstama betona kao osnovog građevinskog materijala koji danas dominira svjetskom građevinskom industrijom. Mikroarmirani beton visokih uporabnih svojstava je nova vrsta betona visoke karakteristične tlačne čvrstoće te s dodatkom vlakana koja poboljšavaju duktilnost pri vlačnom opterećenju. Takav beton u svijetu se pojavio prije dvadesetak godina stoga se može reći da su još uvijek relativno mladi tip betona i tek pronalaze svoju primjenu u građevinskoj industriji. U ovom radu prikazana je oprema, postavka i rezultati provedenog ispitivanja u svrhu određivanja mehaničke impedancije uzoraka mikroarmiranog betona visokih uporabnih svojstava s namjerom proučavanja mehaničkog ponašanja i odaziva uzoraka izloženih vibracijama raznih frekvencija.
Abstract (english)
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.
