Review article

On the example of a high-rise multi-storey (25 floors) building, there were implemented numerical studies and made an analysis of the influence of nodal joints` ductility on the value of force resistance and deformation of structures under seismic loads with intensity of 8 points for the types I and III of base conditions. The ductility of three types of joints is taken into account, namely, self-tapping and tilted screws, connectors with steel smooth dowels. There have been constructed histograms for comparison of general displacements and internal forces in structural members of structures under different soil conditions and various values of joints` ductility under different seismic conditions. It is shown that in the joint nodes, the ductility of joints of different types differs significantly and affects the redistribution of internal forces and general deformations of the building structure. Recommendations are offered, and conclusions are made, including the need for further study of the buildings` seismic resistance with the use of cross-glued wood when changing the volume-planning solutions, taking into account the dissipative properties of the material and elastic-deformable joints in both elastic and nonlinear formulation of the problem.
