This paper presents an experimental study to investigate the effects of distinct loading combinations on modal parameters of pre-stressed concrete beams. Different external loads of static loads and forced vibration were applied on a two-span continuous pre-stressed concrete beam, of which the span length was 7.5 m for both spans. As a result, the variation in model parameters with regard to these external loads was identified at a particular pre-stressed force level. The objective of this study is to employ structural system identification method to estimate the overall deflection of pre-stress concrete beams based on corresponding dynamic and static tests.

Abstract
This paper presents an experimental study to investigate the effects of distinct loading combinations on modal parameters of pre-stressed concrete beams. Different external loads of static loads and forced vibration were applied on a two-span continuous pre-stressed concrete beam, of which the span length was 7.5 m for both spans. As a result, the variation in model parameters with regard to these external loads was identified at a particular pre-stressed force level. The objective of this study is to employ structural system identification method to estimate the overall deflection of pre-stress concrete beams based on corresponding dynamic and static tests.I documenti in SFERA sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
