A methodology of determining the natural frequencies of low-rise buildings (original) (raw)

We live in a world that is constantly faced with natural disasters such as earthquakes, floods, tsunamis and other geological processes. These catastrophes besides causing material damage, are sometimes fatal to people's lives. Therefore, different types of measurements are performed, various studies are made, with the one same goal - to predict disasters, to mitigate and their consequences, and to find a way to protect ourselves from them. One of the most important parameters for design of earthquake resistant structures is the natural frequency of the structure. The main purpose of our research is to find the natural frequencies, i.e. the fundamental periods of objects. Determining natural frequencies, we can find dynamic forces acting on the structure so we can design the constructive elements to resist to these forces. We will do this in order to determine at certain excitation (such as explosions or earthquakes) which frequencies of excitations are dangerous to the construc...
