Structures that do not meet the assessment requirements through screening, design level analysis, or ultimate strength
analysis will need mitigation actions.
[P.sub.y], [P.sub.m], and [P.sub.u] are the yield strength, the ultimate strength
, and the damage strength, respectively, of the specimen.
When the static stress was up to ~85% of the rock's ultimate strength
and the axial strain was up to 80% of the ultimate failure strain, the rock became sensitive to impact load and tended to failure.
(1) A relatively simple methodology for the prediction of axial yield and ultimate strength
based on the assumption of an angle of twist of annealed solid and hollow cylindrical bars was presented.
In this section, the effects of the different opening ratios on the stiffness, ductility and ultimate strength
In the case of the ultimate strength
, however, SM490 exhibited a higher increase rate after the steel fiber reinforcement.
So we assumed that the ultimate strength
was equal to cracking strength for the brittle failure mode of GB-1~4.
Table 5 shows the comparisons between the predicted values of the nominal yield strength [f.sub.syc] and ultimate strength
[f.sub.suc] for the corroded high strength rebars of the modified J-C model with experiments.
Interaction effect, signal to noise ratio (S/N) and mean response were developed and evaluate the influence of each pulsed current parameter at each levels & to calculate percentage of influence by pulsed current parameters on weld strength such as yield strength, ultimate strength
and elongation (%) during PCTIG welding of Al-SiC composite.
The presence of residual stresses in conjunction with high values of axial loads affects the spread of plasticity throughout the height of the steel section and hence may significantly influence both the ultimate strength
capacity and inelastic deformability of the composite steel-concrete cross-section.
In this section, in order to investigate the effect of prestress on the yield strength, ultimate strength
and ductility of RC (reinforced concrete) beam, SRC (steel reinforced concrete) beam, and the changes of mechanical properties of beam after built-in H-steel, four same size numerical models were made, which are prestressed steel reinforced concrete (PSRC) beams, steel reinforced concrete (SRC) beams, prestressed reinforced concrete (PRC) beams, and reinforced concrete (RC) beams, and their mechanical properties were analyzed.
