DOES CORRUGATED WIRE IMPROVE THE ADHESION?

The reinforcement does not improve at all by the fact the wire is corrugated. The conditions for grip relating to transferring forces evenly through-out small-diameter bars, such as the type of masonry reinforcement depend more on the measure of mortar and not the masonry reinforcement.

Grip provided by corrugated bars is only needed when the forces you may have are very large, this only occurs within very thick bars. In the case of the reinforcement a number is worth a thousand words, two bars of 4mm in diameter can transfer securely 10kN, following the required regulations.

This value has been tested on smooth bars of reinforcement. Furthermore the calculation shows the real value of the force that is transferred across the reinforcement (that is met by the minimum quantity requirements) in worst case scenarios, is approximately half.

Consequently the corrugated reinforcement makes no extra benefits of reinforcement that weren’t in the traditional reinforcement. It is important that the technique of reinforced concrete, capable of transferring large forces, use normal plain bars when there is a small diameter. What really improves the transmission of forces is the existence of a suitable cover of reinforcement in the overlap areas.

IS THE ADHESION OF THE MASONRY REINFORCEMENT IMPORTANT?

The adhesion of the reinforcement, if you are using the truss-type, does not intervene with the transmission of
forces between the first and last node of the truss. The transmission of forces in these sections is performed
entirely through the diagonal wires, even without mortar, by virtue of their geometrical configuration, indeformable in their plane.

 
Where it is really essential for the adherence of transmission of forces between the ends of pieces of reinforcement where the truss ends. This is why the overlap needs, a length proportionate to the forces that are transmitted and adequate cover in the overlap area.
To transfer the maximum force that it can withstand equally in the reinforcement, a sufficient overlap length of 250mm is needed (this value must be verified by tests).
To achieve the adequate transfer of adhesion and forces in the overlap areas, the wires must be spaced  when overlapping to a distance equal to their diameter.

DOES AN INCREASE IN THE STRENGTH OF THE STEEL THAT IS USED IN THE REINFORCEMENT IMPROVE THE MECHANICAL BEHAVIOR OF THE WALL?

For control of cracking, the strength of the steel in the reinforcement has no influence on the amount of reinforcement needed, only the area of the crosssection.
When the reinforcement is assigned a structural role, the fact the steel is stronger, does not mean necessarily that you reduce the amount of reinforcement in the same proportions. Because by the requirements of the minimum amount, in the vast majority of cases, steel does not display even half of the resistance. It is the parameter of steel reinforcement which really improves the mechanical performance in the wall, on account of its ductility, not of the resistance.

For this reason, to prevent cracking and for the transmission of forces it is preferable that the steel has a high percentage of deformation at failure (that is the parameter which determines ductility) than high resistance.

IS FLATTENED LADDER TYPE REINFORCEMENT THE SAME AS ROUND TRUSS TYPE?

Having the same wire diameter should not be confused with having the same level of reinforcement. When comparing the different types of reinforcement for crack control the calculation for the amount is to do with the surface area of steel facing any vertical section of the wall.
With truss-type reinforcement there are always three wires in contact the entire length, in contrast, in a ladder type you only have two.

Therefore to meet the minimum requirements of reinforcement, comparing both types the truss type is needed less in the wall per square metre.

Furthermore when the reinforcement is assigned a structural role to withstand lateral side actions the only acceptable geometric configuration is the truss-type, for being the only non-deformable one in its own plane.

WHAT TYPES OF PROTECTION DOES THE REINFORCEMENT HAVE AGAINST CORROSION DO I HAVE TO CHOOSE FROM?

The Eurocode make it very clear what kind of protection against corrosion must the reinforcement have is depending on the environment where the reinforcement is going to be installed:

Inner environment -> Galvanized
Exterior environment -> Epoxy galvanized
Aggressive marine  -> Stainless steel environment

TO IMPROVE THE PERFORMANCE OF MY WALL IN SEISMIC EVENTS, WILL I NEED TO PUT A LOT OF BED JOINT REINFORCEMENT?

For seismic events, the reinforcement itself will improve the mechanical behaviour of the wall because of its ductile properties.

However for the same reasons given previously, this cannot be assigned stability of the wall to the reinforcement itself.

For the reinforcement to be calculated into seismic effects, it should be accompanied by other elements of retention, such as anchors to the pillars.

AS I HAVE BUILT MY WALL VERY HIGH, WILL IT NEED A LOT OF REINFORCEMENT?

The reinforcement is not an element of retention, a wall with lots of reinforcement if it is not sufficiently connected to the structure may fall in its entirety. The masonry reinforcement does not provide stability itself. The reinforcement is there to provide ductility and therefore significantly reducing the risk of cracking. When assigning the reinforcement a mission to structurally support, it is imperative that the wall and support pillars and connected by anchors.
