Buckling of high-strength steel beams
, 2020 This thesis presents experimental and numerical studies on the instability of I-section beams fabricated from high-strength steel (HSS) plates having yield stresses greater than 690 MPa. The research program contains three major tests including the assessment of residual stresses in welded I-sections, the buckling of I-beams and the lateral-torsional ...

Curvature Ductility of High Strength Concrete Beams [PDF]
, 2017 The ductility of reinforced concrete beams is very important, because it is the property that allows structures to dissipate energy under seismic loading, consequently, the brittle fractures of reinforced concrete structures can avoided.

Structural performance of composite beams using advanced modeling for nonlinear analysis
DynaA few studies used full-embedded steel sections in composite beams to reduce their cross sections. This paper presents the behavior of normal and high-strength composite beams having various heights of full-embedded steel sections.
