На підставі експериментальних даних уточнені коефіцієнти At, Ac та Bc,c.90 умови міцності для карнизних вузлів гнутоклеєних рам. Запропоновані практичні рекомендації по розрахунку карнизних вузлів гнутоклеєних рам з врахуванням складного напруженого стану клеєної деревини та встановлені небезпечні точки по довжині карнизного вузла для різних співвідношень кривини карнизного вузла r/h співідношень hmax/L. Розроблені блок-схеми для розрахунку гнутоклеєних рам з співвідношеннями кривини карнизного вузла r/h<4 та r/h≥4
