Such earthquake-induced collisions may cause severe structural damage or even lead to the collapse of colliding structures. The aim of the present paper was to show the results of the study focused on determination of peak impact forces during collisions between buildings exposed to different seismic excitations. A set of different ground motion records, with various peak ground acceleration (PGA) values and frequency contents, were considered. First, pounding-involved numerical analysis was conducted for the basic parameters of colliding buildings. Then, the parametric study was carried out for different structural natural periods, structural damping ratios, gap sizes between buildings and coefficients of restitution. The results of the analysis conducted for the basic structural parameters indicate that the largest response of the analysed buildings was observed for the Duzce earthquake. The parametric study showed that the pounding-involved structural response depended substantially on all parameters considered in the analysis, and the largest response was observed for different ground motions. The results of the study presented in this paper indicate that the value of the peak impact force expected during the time of the earthquake does not depend on the PGA value of ground motion, but rather on the frequency contents of excitation and pounding scenario. It is therefore recommended that the peak impact force for buildings exposed to structural pounding during earthquakes should be determined individually for the specific structural configuration taking into account the design ground motion.<\/jats:p>","DOI":"10.3390\/geosciences10010018","type":"journal-article","created":{"date-parts":[[2020,1,3]],"date-time":"2020-01-03T03:28:53Z","timestamp":1578022133000},"page":"18","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":12,"title":["Determination of Peak Impact Force for Buildings Exposed to Structural Pounding during Earthquakes"],"prefix":"10.3390","volume":"10","author":[{"given":"Seyed Mohammad","family":"Khatami","sequence":"first","affiliation":[{"name":"Center of Semnan Municipality, University of Applied Science and Technology, Semnan 35149, Iran"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-4179-7816","authenticated-orcid":false,"given":"Hosein","family":"Naderpour","sequence":"additional","affiliation":[{"name":"Faculty of Civil Engineering, Semnan University, Semnan 3513119111, Iran"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-9510-144X","authenticated-orcid":false,"given":"Rui Carneiro","family":"Barros","sequence":"additional","affiliation":[{"name":"Faculty of Engineering, University of Porto (FEUP), 4200-465 Porto, Portugal"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-4616-0010","authenticated-orcid":false,"given":"Anna","family":"Jakubczyk-Ga\u0142czy\u0144ska","sequence":"additional","affiliation":[{"name":"Faculty of Civil and Environmental Engineering, Gdansk University of Technology, 80-233 Gdansk, Poland"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-6741-115X","authenticated-orcid":false,"given":"Robert","family":"Jankowski","sequence":"additional","affiliation":[{"name":"Faculty of Civil and Environmental Engineering, Gdansk University of Technology, 80-233 Gdansk, Poland"}]}],"member":"1968","published-online":{"date-parts":[[2019,12,30]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"443","DOI":"10.1002\/eqe.4290160311","article-title":"Pounding of building in series during earthquakes","volume":"16","author":"Anagnostopoulos","year":"1988","journal-title":"Earthq.
