TÓM TẮT
In this study, analytical methods were used to investigate the performance of built-up timber (BT)beams with different designs. A simplified analytical approach based on the gamma and capacitymethods was used to evaluate the initial stiffness, allowable strength, and ultimate strength of BTbeams. Current analytical methods cannot be used to estimate the ductility ratio, thus hamperingthe development of a complete analytical model for BT beams. In this study, a complete analyticalmodel was established for BT beams. In this model, the ductility ratio is determined according toexperimental results. The ductility ratios of specimens were determined using the equivalentenergy method. The developed complete analytical model for BT beams can accurately model thebehavior of these beams. The estimated ductility ratios suggest that specimens with one web andtwo webs are suitably ductile and marginally brittle, respectively. The developed model can beused to predict theflexural performance of BT beams with different design parameters, and theductility ratio can be applied in structural design.
