Title: Ultimate Flexural Capacity of Cracked Polygonal Concrete Sections under Biaxial Bending
Author(s): Troels Brondum-Nielsen
Publication: Journal Proceedings
Appears on pages(s): 863-869
Keywords: axial loads; bending; biaxial loads; computer programs; cracking (fracturing); flexural strength; limit state design; partial prestressing; prestressed concrete; prestressing; reinforced concrete; strains; structural analysis.
Abstract:A method of calculating the ultimate flexural capacity of cracked, fully prestressed, partially prestressed, and nonprestressed arbitrary polygonal concrete sections under biaxial bending is presented. The cross section can be reinforced with any combination of prestressed and nonprestressed reinforcement with individual mechanical properties. The method covers symmetrical and unsymmetrical cross sections and cross sections with polygonal holes. The method is suitable for programmable hand-held calculators.
