In the post-peak region of stress strain curves, strain softening was the dominant behavior and increasing RBP values in the specimens made the post-peak behavior gentler.
The ultimate strengths, failure modes, flexural stiffness, ductility, bending moment-midspan deflection curves, overall deflection curves and strain distribution curves of test specimens are reported.
The test procedure, failure modes, load-vertical displacement curves, moment-rotation curves, load-deformation curves and strain intensity distribution curves were all reported.
The typical failure modes, axial load-vertical displacement curves, bending moment-chord deformation curves, bending moment-rotation curves and strain distribution curves of all specimens are reported.
A pseudo static experiment was conducted to investigate load transmission mechanism, failure mode and seismic performance index based on load-deformation curves and strain curves.
The joint strengths, failure modes, axial load vertical displacement curves, axial load chord deformation curves and strain distribution curves of all specimens are reported.
Temperature distributions, load versus lateral displacement curves, strains in the steel tube and failure modes were obtained and discussed.
Strongly calibrated on experimental and FE analysis moment rotation curves, strain-hardening connection stiffness is evaluated as K sh = 0.005K i.
The experimental scheme, failure modes, load displacement curves and strain intensity distribution curves were also presented.
Ramberg Osgood accurately capture material curve in strain hardening region.
