Predicting the seismic collapse capacity of adjacent structures prone to pounding

Abstrakt

In crowded cities, many structures are often constructed in a very close vicinity; ‎therefore, during severe earthquakes, pounding phenomenon occurs due to out-of-phase ‎vibrations of adjacent structures. In this study, pounding of adjacent structures is investigated ‎up to the occurrence of total collapse. The novelty of this study is performing incremental ‎dynamic analyses to compute the seismic collapse capacities of both pounding structures in ‎one model and removal of the collapsed structure during analysis‎, and proposing ‎modification ‎factors for modifying median collapse capacity of single structures to consider ‎the effect of pounding, which cannot be considered before design process. The results ‎indicate that pounding may significantly affect median collapse capacities of structures ‎compared with those obtained by neglecting the pounding phenomenon. Therefore, different ‎modification factors ‎are required according to structural characteristics. It is noteworthy that ‎the results of this study were obtained using simplifying assumptions and should not be ‎generalized.‎
