Effect of localized damage on lateral–torsional buckling capacity of continuous steel I-beams

This paper investigates the Lateral-Torsional Buckling (LTB) resistance of continuous hot-rolled steel I-beams with localized cross-sectional damage. Due to the alternating sagging and hogging moment regions, continuous beams exhibit spatially varying compression flanges and buck...

High performance fine-grained geopolymer concrete using fly ash and ground granulated blast furnace slag: experimental results and modelling

This study investigates high-performance fine-grained geopolymer concrete (HPFGGC) produced from fly ash (FA), ground granulated blast-furnace slag (GGBFS), and solid sodium metasilicate (SMS), and evaluates Random Forest (RF), XGBoost, and LightGBM models for compressive-strengt...

Multi-scale Evaluation of Rutting Resistance in Reclaimed Asphalt Pavement Mixtures through Linking Binder Rheology with the Hamburg Wheel-Tracking and the IDEAL Rutting Tests

This study proposed a multi-scale framework for evaluating rutting resistance in recycled asphalt mixtures by linking binder rheology with mixture-scale performance. One virgin mixture and seven mixtures containing 50% reclaimed asphalt pavement (RAP) were prepared with three rej...
