fis-5441	Laouche, Nassim; Saimi, Ahmed; Bensaid, Ismail; Dahmane, Mouloud; Ait Atmane, Hassen	A study on the crack presence effect on dynamical behavior of higher-order Quasi-3D composite steel-polymer concrete box section beams via DQFEM	2025	20	.pdf	application/pdf	9200	472	65	Boundary conditions profoundly influenced outcomes: C-F beams displayed asymmetric behavior, with catastrophic sensitivity to steel cracks near the clamped end, while C-C beams resisted buckling degradation until critical composite crack depths ( ac >0.5), beyond which nonlinear collapse occurred. For buckling, C-C beams with steel cracks exhibit clustered values across depths, suggesting limited depth dependency, while composite core cracks in C-C beams display nonlinear behavior: buckling remains stable up to a depth ratio of 0.5 before sharply declining, with spatial variations (e.g., midspan cracks induce the most severe degradation).	cache/fis-5441.pdf	txt/fis-5441.txt
