FIELD: construction industry.
SUBSTANCE: method of experimental determination of dynamic loading in reinforced concrete frame and pin systems is characterised by the fact that support stands are fixed, collar beams and stands are connected rigidly or hinged at the points of frame and pin system by means of connection elements, loading of frame and pin system with specified design static load is performed, and from application of specified load there created is sudden brittle failure of one of the connection elements, which is welded and gauged with pre-fixed force of brittle failure on weld. After that there measured are parametres of created dynamic loading in undamaged stands and collar beams of frame and pin system from sudden brittle failure of gauged welded connection element.
EFFECT: increasing structural safety and survivability of constructions owing to more accurate consideration of dynamic loadings and assessment of dynamic loading in reinforced concrete frame and pin systems in out-of-limit conditions.
