A semi-analytical analysis on beam-column ultimate strength with different initial deflections
Abstract
Purpose
A new beam-column ultimate strength calculation method has been developed and compared with nonlinear finite element analysis by ANSYS and ABAQUS.
Design/methodology/approach
A computer code ULTBEAM2 based on this method has been used for one and three span beam-columns with I-shaped cross-section under axial compression.
Findings
This paper studies the ultimate strength of beam-columns with various initial deflections of different shapes and magnitudes.
Originality/value
The comparison of ULTBEAM2 and finite element analysis shows good agreement for all cases with different initial deflections.
