The paper presents achievements in gluing technique in steel and aluminium structures. Adhesives currently in use and available on the market are characterized from the point of view of their mechanical properties. Design rules of adhesive connections and basic methods for their calculations are mentioned. The most significant examples of the applications of those joints in steel as well as aluminium structures are shown.

The article presents the course and results of the procedure for verifying the stability of the cylindrical shell of an oil tank with a floating roof, under wind load. Two dimensioning methods recommended by standard PN-EN 1993-1-6 were used, i.e. dimensioning based on the stress state and the MNA-LBA procedure. The method of determining the critical buckling resistance ratio from the linear bifurcation analysis (LBA) and the plastic reference resistance ratio from the physically nonlinear analysis (MNA) has been presented. Comparison of the results obtained with the use of the indicated design methods revealed significant discrepancies in the stress intensity levels of the analysed shell. When using the stress-based dimensioning method, it was shown that the buckling strength was exceeded by 33%, while the results of the MNA-LBA procedure indicated a 33% reserve of the capacity of the analysed system.

This study includes a detailed analysis of using adhesives in reinforcement of steel structures. Two types of structures were experimentally investigated: box girder and knee joints. The numerical calculations were done on the basis of the experimental investigations performed at CUT Cracow (box girder) and BTU Cottbus (knee joints) with the use of numerical programme Abaqus based on the Finite Element Method. The numerical results were compared with the experimental ones.
