| Summary: | 碩士 === 國立臺灣科技大學 === 營建工程技術學系 === 83 === Usually ,the collapse of buildings leaded by seismic
impulsion attributes to the insufficient resistant
capacity of structures. However , adjacent buildings with
insufficient separation often collide into each other during
an earthquake and lead to instant collapse of buildings in
recent earthquakes.Therefore,pounding is one of the important
problems in the field of earthquake engineering. In this
article ,the fondmental pounding characterist- ics of two
single story steel model frames were experim- entally studied,
and are expected to get understanding in pounding. The
experiments are snap back tests , and the influencing
parameters ( including contact area ,pound- ing mechanism
stiffness ,size of plates , and structure stiffness ) are
investigated for structural pounding. In low initial pounding
velocity range, pounding velo- city shows insignificant
distinction in pounding freque- ncy(inversion of half of the
pounding contact time). The decrease of pounding mechanism
stiffness reduces the po- unding reaction and pounding
frequency , but structure stiffness has no singnificant
influence on pounding res- ponses.
