摘要：

Cyclic tests on two large-scale models of existing bridge piers with rectangular hollow cross-section were performed in the ELSA laboratory. The prototype structure is an existing reinforced concrete highway bridge constructed in Austria in 1975. The piers presented several seismic deficiencies and consequently they showed poor hysteretic behaviour and limited deformation capacity as well as undesirable failure modes that do not comply with the requirements of modem codes for seismic-resistant structures. Experimental data are compared to numerical and empirical predictions. Copyright (C) 2003 John Wiley Sons, Ltd.
