Behavior of concrete beams reinforced with hybrid steel ...

2018-12-1  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.

MODELING OF REINFORCED CONCRETE BEAMS WITH

2014-7-7  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

2016-3-15  The stroke of the testing machine was gradually increased until flexural failure was reached, manifested by concrete crushing. 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.

2013-3-6  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.

2011-8-13  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 ...
