A. Filiatrault et al., POUNDING OF BUILDINGS DURING EARTHQUAKES - A CANADIAN PERSPECTIVE, Canadian journal of civil engineering, 21(2), 1994, pp. 251-265
The main objective of this paper is to provide information to structur
al engineers on how to consider and mitigate the phenomenon of poundin
g between adjacent structures during earthquakes. The first part of th
e paper reviews the problem of seismic pounding; observations of damag
e from pounding during recent earthquakes are described as well as the
pounding potential for buildings in large Canadian cities. A review o
f literature on analytical and numerical studies of earthquake poundin
g is presented along with methods that have been proposed to mitigate
pounding. In the second part of the paper, the seismic behaviour of th
ree closely spaced, Canadian code designed, plane steel frames is inve
stigated. Nonlinear time-step dynamic analyses and nonlinear elastic g
ap elements, to model pounding, are used for this purpose. Several par
ameters, such as separation distances, pounding locations, and ground
motion characteristics, are considered.
