They reported that beams strengthened with CFRP wrapping carried higher applied load; no de-bonding was observed at failure; CFRP wrapping resulted in a gradual plastic strain increase in steel bars; increase in ultimate strength
was higher for beams with a lower percentage of steel reinforcement.
For platforms with high consequence category, API RP2A requires a minimum RSR of 1.6 obtained from static in-place ultimate strength
analysis (Static Push-over Analysis).
However, the ultimate strength
of the joint with the higher RC slab thickness was lower because of the increase in the maximum stress on the bottom flanges of the steel beams caused by the increased thickness of the RC slab.
The actual stress level 5 in the test is between 69.2 and 70.4 MPa, which is about 98.16-99.86% of the long-term strength and 84.39-85.85% of the ultimate strength
As was expected the experimental and predicted axial yield and ultimate strength
of solid cylindrical bars deformed by torsion increases with the angle of twist of the process, as shown in Table 3.
As seen, the ultimate strength
and energy absorption of the system decrease as the opening ratio increases.
As a result of comparing the yield strength and ultimate strength
increase rates among all specimens depending on the concrete type, as presented in Table 5 and based on the load-displacement relations, the combination of HSB800 and HSC showed a higher increase rate in the yield strength in comparison with the combination of HSB800 and LSC.
The maximum stress of the failure section for the stone slab was equal to ultimate strength
of the stone material.
Equations (4), (5a), (5b), and (5c) can be used to determine the parameters A, B, C, and n, and the corresponding yield strength and ultimate strength
can be obtained according to (4) according to the strain and ultimate strain of the corroded steel bar under dynamic loading.
The specimen average, standard deviation, and coefficient of variance with respect to ultimate strength
were calculated for each group of replicates.
A lightweight aluminium casing gives ultimate strength
The new rules' ultimate strength
will be determined by the weakest link, so all countries have a stake in making sure that no member lacks the technical capacity to deliver on treaty obligations.
