s] is the modular ratio, the minimum reinforcement ratio required to maintain constant strain at the crack, when the cracking load
is applied to the member and held constant, is (Massicotte et al.
The plotting of the stress fields along the beam (Figs 10-11) shows the distribution of principal stresses at the first cracking load
and at the ultimate load, respectively.
Therefore, it is difficult to determine the value of the diagonal tension stress and the cracking load
in a RC beam because the distributions of shear and flexural stresses are not known precisely.
All cracks appear under cracking load
dividing the beam into a number of blocks.
The stiffness of tested beams was also significantly reduced when the cracking load
Table 3 shows the variation of diagonal cracking load
According to the test results and the finite element analysis results, 1:3 model joint cracking load
is 2000 kN, which is twice the design load.
First, cyclic loading below the cracking load
enabled researchers to assess the cracking performance of the field-cast UHPC and its bonding to the precast concrete.
In this case, by definition the cracking load
would be equal to the initial residual load ([F.
A force control with 2 actuators is applied initially to reach fast on the point of the cracking load
(3254 kN) up to 3400 kN with 10-50 kN/min loading speeds.
This is due to the fact that, when evaluating the SLS as a whole, the SLS of cracking is generally the less restrictive one, whereas the bond properties do not have influence on the SLS of stresses in concrete, and have only influence at loads close to the cracking load
for the SLS of deflections.
