Self-compacting concrete (SCC) has become increasingly significant in contemporary construction due to its excellent rheological characteristics and improved constructability. Nevertheless, its quasi-brittle nature and limited fracture toughness present notable challenges. This research explores the combined effects of utilizing waste glass coarse aggregates (WGCA) and hooked-end steel fibers (SFs) on the fracture behavior and mechanical properties of SCC subjected to complex loading scenarios. WGCA was incorporated to replace natural coarse aggregates (NCA) at replacement levels of 15 %, 30 %, and 45 %, while SFs were introduced at volume fractions of 0.1 %, 0.3 %, and 0.5 %. A total of 240 semi-circular bending (SCB) specimens were evaluated under four distinct loading modes (I, I/II, II/I, and II) after curing for 28 and 56 days, in addition to 60 cubic samples for assessing compressive strength. The findings indicate that substituting NCA with WGCA up to 30 % improves both fracture toughness and compressive strength, attributed to enhanced matrix densification resulting from the pozzolanic activity of glass particles. However, exceeding this percentage leads to a decline in performance due to inadequate bonding at the interface between the aggregate and matrix. The inclusion of SFs effectively addresses this limitation by improving crack-bridging mechanisms, stiffness, and ductility. The most favorable outcomes were observed with 30 % WGCA and 0.5 % SF, which provided exceptional resistance to crack propagation across all loading modes. This extensive study offers valuable insights into the sustainable use of WGCA and SFs in SCC, tackling both environmental and structural issues. The results highlight the potential benefits of integrating recycled materials and fiber reinforcement to enhance the performance of SCC under practical loading conditions
