Stabilization and stiffening of unique longspan bridge transport constructions

摘要

The article deals with the unique systems of longspans,gives examples of such constructions in Russia and abroad,as well as the main periods of their development history.Particular attention is paid to accidents and disasters that took place at various times.Based on the analysis of suspended and cable-stayed systems'destruction,the main causes of damage are investigated and systematized,which is a very important element in ensuring the security of unique longspan systems.Recommendations are made on improving the stabilization and stiffness of bridge constructions.
