This master’s thesis analyzes various technologies used for pile compozite construction (steel and concrete) – column and beam installation in Lithuania and other countries. Reviewed composite beams and columns use, installation techniques and installation technologies are compared with other structures such as concrete and metal. This thesis presents composite structures components, materials with research in this area. The practical research part of this thesis contains of analysis to various components of concrete mix, including parameters like: ratio of the large aggregates (4/16 fraction gravel) between total aggregates of a mixture the influence on on-steel contact surface friction parameters. Evaluations were made of chosen composite frame, reinforced concrete frame and the metal frame installation technology compared to alternative technologies, based on composed relevant criteria system and also using multi-criteria evaluation. By using multi-criteria evaluation system COPRAS, a rational engineering solution of the frame was determined taking into account that all structures are connected using screw connections. |
