The article examines the role of dynamic collapse modelling for reinforced concrete structures exposed to emergency dynamic loads. The authors reviewed methodological approaches to test simulation of emergency loads applied to reinforced concrete structures with the aim to consider the scale effects revealed in manufacturing of test models of reinforced concrete structures. The comparative analysis is based on the examples of the authors’ previous computational and experimental investigations of the reinforced concrete building frames made of cast-in-situ reinforced concrete. The article determines regularities in the impact of physical and geometric similarities applicable to models and full-scale specimens. The obtained results can become a base for a mathematical description of the impact produced by scale effects that shall be considered in simulation of emergency dynamic loads for the given structures.
