Features of prestressed trusses of the "arch with tightening" type for seismic effects

The article presents experimental studies of prestressed metal structures that are made by a truss with tightening on models in the mode of free oscillations, as well as in the modes of resonant cyclic forced oscillations, taking into account various similarity criteria. Various constructive forms of prestressed metal structures are considered by analyzing the results of theoretical and experimental studies and generalizing domestic and foreign experience in designing and construction for farms with tightening. © 2022 Author(s).
