The final thesis deals with the analysis of the behavior of a portal frame during dynamic excitations. The portal is composed of three blocks, which are interconnected and connected to the ground through elastic contacts. In the first part of the final thesis, the kinematics of the blocks are analyzed, leading to equations that describe the displacement of the blocks. Elastic contact is introduced, and its characteristics are defined, enabling the formulation of the stiffness matrices for the contact. Following that, the dynamic problem and the equations of motion are defined. The developed numerical model, which allows for the simulation of the dynamic response of the portal consisting of three blocks (two columns and a beam), has been implemented in the Python programming language. In the experimental phase, tests were conducted on glued block systems at the Structural Laboratory of the Faculty of Civil Engineering in Rijeka. First, the material characteristics of the silicone adhesive, which will be used in further calculations during the analysis of the portal under dynamic excitation, were determined. After that, an experiment involving the dynamic excitation of the block portal was conducted. After conducting the experiments, the results of the experiment were compared with the results of the numerical model programmed in Python. After validation and calibration of the numerical model, it was concluded that it can be used for simulating block systems with different geometric characteristics connected by elastic contacts.
