Analysis of seismic separation gap between two adjacent reinforced concrete buildings

Investigation of Pounding between Two Adjacent Building Models with Experimental Methods

“…With i representing the model number, the terms ai0 and ai1 in the damping matrices in equations ( 3) and ( 4) are calculated according to Rayleigh Damping [21]. The vectors of acceleration (Ü1 and Ü2), velocity (U ̇1 and U ̇2), and displacement (U1 and U2) in Equations ( 1) and ( 2) are given in Equations ( 5) and (6). Üg in equations ( 1) and ( 2) represents the ground accelerations.…”

“…Pounding, which could occur due to an insufficient seismic gap, is an issue that needs to be examined in terms of structural dynamics and earthquake engineering. For this purpose, there are several numerical but limited experimental studies in the literature on subjects such as the pounding force between two adjacent structures, the number of pounding, the moment of collision, and the determination and investigation of the size of the seismic gap [3][4][5][6][7][8]10].…”

“…They concluded that the pounding effects are sensitive to the change in peak ground acceleration and the size of the gap between buildings. In order to determine seismic gaps under seismic effects, besides the pounding models used in numerical analysis, studies on the effects of gaps between adjacent buildings, taking into account different parameters, were carried out by Saxena et al [6]. In addition, Khatami et al [7,8], in their studies, investigated the effect of seismic gaps in the presence of lateral stiffness irregularity, soft stories, and regular and irregular adjacent structures using an experimental model of Takabatake et al [9], which had two frames with single span and four-story.…”
