Summary results: mean ultimate load
and mean load-deflection slope values and the related coefficients of variation are summarized in Table 3.
Furthermore, the tie-down ring system should have a 1.5x safety factor for ultimate load
situations at 11,250 pounds, and of course, the legacy design could not meet that.
The results showed that, for all strengthened CFST models using one layer of CFRP sheet, CFRP had no significant enhancement in the ultimate load
capacity when wrapped along 50, 75, and 100% of the length of the specimens.
Both the yield and ultimate load
increased as the strain rate increased.
According to the analysis of Table 8, the yield load/ displacement, ultimate load/displacement, and ductility ratio of members are all decreased to some extent after rebar corrosion, and the decrease of yield load/displacement and ultimate load
. Figure 8 shows the values of the ultimate load
([P.sub.u]) under moisture conditioning.
It can be seen that the strengthening effect for first-cracking load, steel-yielding load, ultimate load
, and corresponding displacement of the beams UB-GR-300-T and UB-UG-300-T is inconspicuous comparing to the initially strengthened specimens UB-GR-0-T and UB-UG-0-T, as shown in Table 7.
The testing was load-controlled in the elastic stage, the increment of load was about one-tenth of the calculated ultimate load
, and displacement control was used in the elastoplastic stage.
Compared to traditional straight-grip and push-button configurations, the new pendant control's rocker switch and comfort-fit design give operators ultimate load
command while reducing hand strain and fatigue--allowing for safer and more efficient operation of hoists and industrial equipment with momentary operation.

for specimens with and without fibres
Then the timber column drops until ductile crushing at ultimate load
. While the ultimate load
is reached, wood cell themselves fold into S shapes forming characteristic compression wrinkles due to local buckling of wood fibers become visible .
