George Mason University - Online Applied Behavior Analysis Graduate Certificate In those cases, manipulating the consequences may be the only available tool for changing behavior. That manipulation is largely the role of reinforcement. A basic example is the classic one: Johnny is given a homework assignment at school the antecedent.

It is a versatile constructional material which is widely used in the construction industry for making of the reinforced concrete. Reinforcement concrete RC is a composite material made up of concrete and some form of reinforcement — most commonly steel rods, bars, wires or mesh of steel rods and steel wires.

The steel reinforcement bars usually consists of such shape and size that they may easily be bent and placed in the concrete so as to form a monolithic structure. The properties of thermal expansion for both steel and concrete are approximately the same.

This along with excellent bendability property makes steel the best material as reinforcement in concrete structures. Another reason steel works effectively as reinforcement is that it bonds well with concrete. When passive reinforcement steel bars is employed, the structure is known as reinforced concrete structure.

In pre-stressed concrete structure, the reinforcement steel wire is stressed prior to subjecting the structure to loading, which may be viewed as active reinforcement.

Passive steel reinforcing bars, also known as rebars, should necessarily be strong in tension and, at the same time, be ductile enough to be shaped or bent. Steel rebar is most commonly used as a tensioning devise to reinforce concrete to help hold the concrete in a compressed state.

Concrete is a material that is very strong in compression, but virtually without strength in tension. To compensate for this imbalance in a concrete slab behavior, reinforcement bar is cast into it to carry the tensile loads. The surface of the reinforcement bar may be patterned to form a better bond with the concrete.

Reinforced concrete gets its strength from the two materials, steel and concrete, working together.

To get them working together, it is critical that the steel be adequately bonded to the concrete. Achieving this bond is called developing the bar, and many aspects of reinforcement design are geared toward achieving development.

Steel rebars are the time proven match for reinforcing concrete structures. RC structures are designed on the principle that steel and concrete act together to withstand induced forces. The aim of the reinforced concrete designer is to combine the reinforcement with the concrete in such a manner that sufficient of the relatively expensive reinforcement is incorporated to resist tensile and shear forces, whilst utilizing the comparatively inexpensive concrete to resist the compressive forces.

To achieve this aim, the designer needs to determine, not only the amount of reinforcement to be used, but how it is to be distributed and where it is to be positioned.

These decisions of the designer are critical to the successful performance of reinforced concrete and it is imperative that, during construction, reinforcement be positioned exactly as specified by the designer.

Originally concrete structures were made without reinforcement. The use of rebars has started in construction since at least the 18th century. Earlier cast iron was the materials for the rebars.For example, a limited time sales bonus is not positive reinforcement.

It is an example of a reward. Sustained quarterly sales bonuses based on exceeding goals is positive reinforcement. Likewise, negative reinforcement is not punishment. For example, suspending an .

What’s the “Positive” in Positive Reinforcement?

It is a versatile constructional material which is widely used in the construction industry for making of the reinforced concrete. Positive reinforcement is the process of recognizing and rewarding a desired behavior in an effort to encourage its continuance.

Positive reinforcement can consist of praise, offering incentives to continue the behavior or showing appreciation for effort. The type of reinforcement used can play an important role in how quickly a behavior is learned and the overall strength of the resulting response. Understanding Reinforcement in Psychology Reinforcement is a term used in operant conditioning to refer to anything that increases the likelihood that a .

Long-Term Results Positive reinforcement is often associated with a rewards system, when, in reality, it is an attempt to create sustained positive behavior. For example, a limited time sales bonus is not positive reinforcement.

It is an example of a reward. Sustained quarterly sales bonuses based on exceeding goals is positive reinforcement. Timing is critical to the effectiveness of positive reinforcement.

It is important for an individual to feel that the goal is achievable and that reinforcement is attainable. It is also important that the reinforcer is not something the child already has free access to.
