Optimizing Parameters for Anticollision Systems between Adjacent Buildings under Earthquakes

Abstract EN

Adjacent buildings with anticollision system would have the possibility of pounding under earthquake if there is insufficient separate distance between the two buildings.

The effect of pounding and earthquake characters on the optimum parameters for anticollision system is studied through time-history analysis method in this paper.

Interstory displacement ratio, energy consumption ratio, and the total strain energy of the two buildings are considered as control variables.

The results show that the pounding between adjacent buildings will reduce the range of optimum parameters, and earthquake characters also have effect on the selection of optimum parameters.

Therefore, it is strongly recommended to input more than three ground motion records for a time-history analysis to get the optimum parameters considering the effect of pounding and earthquake characters.
