About reliability of design on wind loads with regional building code of Krasnodar Krai
Incoming article date: 29.08.2019Paper considers maximum annual values of mean wind velocity in all plain, piedmont and seaside regions of Krasnodar Krai for more than 60-year period of monitoring. Substantial areal differencies of trends of wind velocities change are revealed in north-east, seaside and central zones. Simultaneous analysis of time series of vane and anemometric measurements of mean wind velocities over 1965-2012 allowed to reveal a period of significant increase of wind velocities up to 1977 and detect a gradual decrease of velocities in 1979-2012. Significant areal differencies in wind velocity trends in north-east, seaside and central zones of region are shown. It is shown that time series of wind velocities used for SNKK 20-303-2002 allowed to develop a reliable base for wind loads which provides up to date an annual certainty level 0.98 adopted in the current version of building code SP 20.13330.2016 "Loads and actions".
