摘要

In the present paper the fundamental period of Reinforced Concrete (RC) frames of varying structural characteristics (number of stories, irregularity in elevation, presence and position of masonry infills, etc.) has been evaluated with the main objective of deriving period-height expressions for classes of European RC buildings. To this purpose, relationships from design codes and reported in the literature have been examined and their results have been compared to those ones obtained from numerical simulations (eigenvalue analyses) and experimental measurements (ambient vibration analyses). A wide parametric analysis has been carried out on several structural types selected and detailed (simulated design) to represent typical European RC buildings without earthquake RC design. As for the experimental evaluation of T values, ambient vibration analyses based on measurements carried out using quick survey techniques have been used. High differences between the values obtained from code relationships and numerical and experimental results have been found and discussed in the paper. Finally, future developments of the study have been outlined.
