| Summary: | 碩士 === 國立臺灣科技大學 === 營建工程技術學系 === 83 === During 1985 Mexico Earthquake, structural pounding is one of
the major reasons for the collapse of many buildings. This
collision, commonly called ''structural pounding'' occurs during
an earthquake when due to their different dynamic
characteristics,adjacent buildings vibrate out of phase and
there is insuficientseparation between them. This study
investigates the structural pounding between multispan ductile
moment resisting frames. It is found that among theadjacent
structures under pounding, the structure with longerperiod and
lighter weight will have it dynamic responseThe parameters of
total ductile energy dissipation,plastic hinge rotation of
members, and maximumthe most sensitive to the structuralheir
changes under pounding are valuableresistance evaluation and
retrofit. In addition, it is found that linking the adjacent
structuresseparated with construction joints is an effective
way tomitigate the pounding damage for the adjacent structures
withsimilar story mass and building period.
