| Abstract [eng] |
The use of composite structures of timber (CLT) and steel beams in modern construction is becoming increasingly popular, but the methods of connecting elements and calculation methodologies have not been sufficiently investigated, and the influence of shear connections on the strength and stiffness of composite floors has not been fully evaluated. The final master‘s project analyses the composite structure of timber (CLT) and steel beams. A literature analysis of shear connectors was performed, in which the characteristics and types of different joints were analysed. Based on scientific publications, an analytical study was conducted to evaluate the accuracy and reliability of the load – bearing capacity calculation methods presented in current standards and by scientist. The calculated bearing capacity of the connections was compared with the results of experimental studies, and it was determined which methodology provides the most accurate results. In order to evaluate the effect of shear connectors on the structural behaviour of timber and steel composite floors, three composite beams with different stiffness of shear connectors were designed. The effect of connection stiffness on the strength and stiffness of the composite floor was evaluated using the engineering finite element calculation software DLUBAL RFEM 5. |
