“…Because structure frames pounding without bumper involves concrete-to-concrete impact, an improved Kelvin model proposed by Jankowski 21 is utilized to simulate pounding responses of adjacent buildings. The method is widely used by many studies and its effectiveness has been proved by several studies such as Polycarpou and Komodromos 31 and Naserkhaki et al 32 The expression of the pounding force model regarding to concrete-to-concrete impact is shown as 18…”

Insufficient gap between adjacent buildings may lead serious poundings under seismic loadings. Installing polymer bumpers may decrease the pounding forces between colliding buildings, which can prevent column yielding from overlarge shearing forces. This article focuses on the analysis on energy responses of adjacent structures equipped with polymer bumpers. Based on a novel pounding analysis method, systematic comparisons of structural pounding performance are conducted and specific results are obtained and discussed. First, time history responses for pounding force, displacements, and yielding shearing forces in selected floors are calculated. Then, energy response analysis considering viscoelasticity of bumpers is investigated. Afterward, under different seismic waves, input energy response, pounding force procedures, and story displacements are studied and discussed. And finally, parametric studies on energy responses, including gaps, sizes, and viscoelasticity parameters, are carried out to investigate influence sensitiveness of bumper parameters. The results show that the novel viscoelastic pounding force model is effective in simulating and calculating adjacent structural pounding with polymer bumpers. Although, in many cases, viscoelasticity has little effect on pounding forces and energy response time histories, it still has certain influences on maximum values. And, equipping with polymer bumpers on adjacent buildings can decrease maximum pounding forces under all types of seismic waves, but pounding times and maximum displacements of stories increase after being equipped with bumpers. By comparing cases under different seismic waves, energy responses show sensitive characteristics to different earthquake waves. Besides, gaps, sizes of bumpers also have significant influence on energy performance. They affect peak yielding energy and peak damping energy significantly.

“…Muthukumar et al [13] studied the seismic pounding response of adjacent buildings applying various impact models and introduced Hertz damp model for pounding impacts. Naserkhaki et al [14] used a visco-elastic contact model to simulate the pounding force for adjacent buildings resting on the soil. Naderpour et al [15] presented the nonlinear viscoelastic model of impact force with the considered relation between the coefficients of restitution and damping.…”

“…Structural design codes indeed regulate seismic separation requirements for adjacent buildings; however, the risk of building pounding is still high [14]. Moreover, the impact of the pounding effect is not taken into consideration in practical design codes.…”

Pounding phenomena considering structure-soil-structure interaction (SSSI) under seismic loads are investigated in this paper. Based on a practical engineering project, this work presents a three-dimensional finite element numerical simulation method using ANSYS software. According to Chinese design code, the models of adjacent shear wall structures on Shanghai soft soil with the rigid foundation, box foundation and pile foundation are built respectively. In the simulation, the Davidenkov model of the soil skeleton curve is assumed for soil behavior, and the contact elements with Kelvin model are adopted to simulate pounding phenomena between adjacent structures. Finally, the dynamic responses of adjacent structures considering the pounding and SSSI effects are analyzed. The results show that pounding phenomena may occur, indicating that the seismic separation requirement for adjacent buildings of Chinese design code may not be enough to avoid pounding effect. Pounding and SSSI effects worsen the adjacent buildings' conditions because their acceleration and shear responses are amplified after pounding considering SSSI. These results are significant for studying the effect of pounding and SSSI phenomena on seismic responses of structures and national sustainable development, especially in earthquake prevention and disaster reduction.

“…In another study [37], it was shown that the code-prescribed width of the separation joint is not sufficient on soft soils especially when the fundamental periods of the soil and structure were close to each other and also to the excitation frequency due to resonance phenomenon. Naserkhaki et al [38] developed a model consisting of adjacent shear buildings responding in elastic range resting on equivalent springs and dampers. They observed that pounding and SSSI together resulted in a more severe response in terms of maximum shear and displacements of top floor.…”

Abstract 8In cities and urban areas, building structures located at close proximities inevitably interact under 9 dynamic loading by direct pounding and indirectly through the underlying soil. Majority of the 10 previous adjacent buildings pounding studies that have taken the Structure-Soil-Structure Interaction 11 (SSSI) problem into account have used simple lumped mass-spring-dashpot models under plane-strain 12 conditions. In this research, the problem of SSSI-included pounding problem of two adjacent 13 symmetric in plan buildings resting on a soft soil pr...
