The complex study of the pounding effects contemplates a multivariable relationship, presenting the opening to various unexpected scenarios in which reinforced concrete structures could face. Structural impact models are intended to quantify impact loads. Although the first analytical models take into account the mechanisms based on relative stiffness and displacement, the most up-to-date models even contemplate the effects of damping in viscoelastic systems, assuming transfers of kinetic energy into deformation energies. However, structural dynamics exposes a series of criteria to be taken into consideration when analysing impacts, such as modal analysis, equations of motion in damped systems, responses to harmonic excitations with constant and variable amplitudes, frequencies natural and modes of vibration, among others. In the present investigation called "Study of the pounding effects on the dynamic response of two adjacent reinforced concrete structures", the seismic analysis was carried out on two idealized type structures, the application of the Hertz-Damp model, the energy transfer analysis in the collision between both structures, the quantification of the loads and the obtaining of the response parameters in a post-collision structural analysis. The objective of the research is to obtain structural responses by means of the spectrum analysis of accelerations and time history with SIN functions, and amplitudes based on ZUCS/R*G, in order to induce variations in the seismic acceleration factor and the excitation frequencies, to estimate responses in proximity to structural resonance for each reinforced concrete building, in order to contemplate critical requests for each structure. In general terms, pounding affects the seismic behaviour of structures, modifying unexpectedly their structural response parameters in a seismic event. In the City of Cusco, when an earthquake greater than 6.50 Mw occurs and there is been a seismic joint smaller than the one regulated, the pounding will directly affect the structural elements, amplifying the internal forces in the columns and exposing them to depend on the security factors to avoid the failure of each element in contact against a possible collapse.
