Abstract

This study aims to deepen the understanding of the dynamic behavior in timber and concrete composite systems, focusing on the analysis of panels with Cross Laminated Timber (CLT) and reinforced concrete sections. To achieve this, knowledge of their material properties, such as material densities, elasticity and strength modules, and geometric characteristic, as cross-sectional inertia, is necessary. These parameters influence the dynamic behavior of structural elements and allow the assessment of their susceptibility to vibrational movements, which can generate a sense of insecurity among users. Based on experimental and numerical results of natural frequency, relationships were established to analyze the dynamic behavior of these plates that meet regulatory criteria. Five plates with different configurations of connectors between CLT and concrete were evaluated using accelerometers along the longitudinal axis of the pieces. The obtained values for the first of the most critical natural vibration frequency were above 17 Hz. These results reliably meet the criteria of the standard NBR 7190-1:2022 for simplified analysis.
