Read More2018-12-1 For specimens with FRP rebars as upper and lower reinforcement, the failure was crushing in concrete which is the unfavorable brittle failure in spite of increasing the area of reinforcement. Therefore, providing steel rebars to the FRP rebas in the top and bottom reinforcement ensures the desirable ductile flexural behavior.
Read More2020-5-16 Typical appropriate reinforced flexural failure of concrete crushing occurred for all specimens. For steel RC specimen BA, as the steel reinforcement yielded, crack width and deflection significantly increased, until, finally, the top extreme concrete compressive fiber

Regarding the transverse reinforcement, three layouts with different spacing were tested: 2.5 mm of spacing (ρ w = 0.76%, labeled H), 5 mm of spacing (ρ w = 0.38%, labeled L), and no transversal reinforcement (labeled with an N for no- reinforcement ...
Read More2014-7-7 Modeling of reinforced concrete in ANSYS starts by choosing one of three methods that can be used to model steel reinforcement in finite element models. These methods are (Figure 1): 1) discrete method; 2) embedded method; and 3) smeared method. In the discrete method, reinforcement is modeled using bar or beam elements

Fig. 2 shows load-mid-span deflection curves of the beam specimens. In beams with reinforcement ratios of 0.15% and 0.39%, concrete crushing was accompanied by rupture of the longitudinal steel.

Read More2013-3-6 The crushing strength of concrete is influenced by a number of factors in addition to the water/cement ratio and the degree of compaction. The more important factors are: (1) Type of cement and its quality. Both the rate of strength gain and the ultimate strength may be affected. (2) Type and surface texture of aggregate.

Read More2011-8-13 For concrete crushing, the Whitney rectangular stress block is used to approximate the concrete stress distribution at ultimate strength conditions. For FRP reinforcement, the linear-to-failure stress-strain relationship must be used. If the FRP reinforcement ruptures, sudden and catastrophic failure can occur. Therefore, concrete crushing has ...

Conceptu-ally, steel-reinforced concrete is designed to ensure that the nominal moment capacity exceeds 120% of the cracking capacity: M n C 1.2M cr (ACI 318-14). Additionally, minimum reinforcement is intended to provide crack control; that is, once ...
