The Difference

Structural elements such as beams most times experience shear failure suddenly without prior warning and this is different from bending failure which occurs by gradual yielding of tensile reinforcement. A previous experimental research showed that the use of lightweight foam concrete with a fiber mixture has a higher ductility in comparison to the normal concrete. It is also one of the solutions to increase the shear strength capacity of concrete and also has the ability to cause relatively small crack patterns and spread. This research, therefore, aimed to determine the shear behavior of fiber-reinforced foam concrete using a finite element with 3-dimensional modeling in an ATENA V5 software. Moreover, the results obtained were were compared with the findings of the experimental research. The test object used was a beam designed with 15 cm x 30 cm x 220 cm dimensions and the stirrup spacing for the fiber-reinforced foam concrete (BBSN-20) was 20 cm while the normal beam (BN-25) had 25 cm. The numerical analysis was observed to have shown closer values to the experimental results with the difference in the ultimate load on the BBSN-20 and BN-25 recorded to be only 7.73% and 12.6% while the ultimate deflection was 6.92% and 32.45% respectively. Meanwhile, the beam destruction patterns in both the numerical and experimental models were similar but the numerical analysis showed the two beams modeled did not experience shear failure as planned.

Diagonal Crack

According to tests of 8 T concrete beams with HRB500 steel bars as stirrup, the shear behavior of beams was researched under uniform load, and the influencing factors of diagonal crack width were analyzed, such as the different concrete strength, stirrup spacing and the welded wire fabric. Experimental results show that concrete beams with HRB500 steel bars as stirrup show similar behavior to the beams with conventional stirrup, and the stirrups yield can be achieved which meets the requirement of shear behavior in structure. In addition, the welded wire fabric can be used as one of the new kinds of reinforcement to control diagonal crack width.

Primary Reduction

This paper reviews the evidence for a secondary transfer effect of intergroup contact. Following a contact’s typical primary reduction in prejudice toward the outgroup involved in the contact, this effect involves a further, secondary reduction in prejudice toward noninvolved outgroups. Employing longitudinal German probability samples, we found that significant secondary transfer effects of intergroup contact exist, but they were limited to specific outgroups that are similar to the contacted outgroup in perceived stereotypes, status or stigma. Since the contact-prejudice link is bidirectional, the effect is inflated when prior prejudice reducing contact is not controlled. The strongest evidence derives from experimental research. Both cognitive (dissonance) and affective (evaluative conditioning) explanations for the effect are offered.
