Özet
Cross-laminated timber (CLT) is recognized as a leading engineered wood product because of its sustainability, reduced carbon footprint, and growing application in civil engineering structures. However, the numerical modeling of CLT systems is challenging due to numerous connection details and the lack of standardized models. This study evaluates the effect of different types of experimental data on the finite element model (FEM) updating process for CLT panels. To this end, 30 CLT panels with varying configurations were subjected to monotonic loading to characterize their load-displacement responses, and ambient vibration tests were conducted to identify their dynamic characteristics. Initial FEMs of the CLT panels were developed and then updated using three different approaches: displacement-based, frequency-based, and a combined method. The results indicated that updating based solely on displacement data accurately captures static responses but fails to adequately represent modal behavior. In contrast, frequency-based updating yielded reliable natural frequencies but resulted in significant discrepancies in displacement predictions. The combined updating method provided consistent results, reducing displacement differences to 0-14.29% with an average of 3.23%, while maintaining frequency discrepancies below 5%. Overall, the results show that obtaining a reliable numerical model of CLT systems requires combining different types of experimental data.
