Abstract

The high-speed transport highway (HSTH) connecting St. Petersburg, its suburbs and Leningrad Region was developed in student research projects. The highway is a large-span and altitude cable-rod arch system of overpass design. The article deals with the problem of preserving the bearing capacity and safety of HSTH elements and protection against progressive collapse (PC) under the influence of special loads. The considered section of the highway is located in the Gulf of Finland between Kronstadt and B. Izhora. Possible different influences and loads during the operation of the section are given. A disaster scenario has been analyzed: the ship leaves the fairway and hits the elements of the column, which are destroyed or receive great efforts. Schemes with destroyed elements are calculated for the special combinations of loads. As a result, the stress-strain state of structural elements is determined and indicates the impossibility of PC and ensures the survivability of the HSTH.
