The article presents the results of research work joints of reinforced concrete columns without increasing or reinforced with metal clips with short-term dynamic loading. For realization of this task has developed a program of experimental and numerical their research. As a result of experimental studies were obtained scheme of strain, crack formation and destruction, as well as the values of failure loads of experimental samples. The obtained results are compared with the data of numerical calculations performed with the help of the calculation of a program based on the finite elements method. The results of experimental and numerical calculations have shown good agreement and reliability upgrades joints columns metal clips.
