While our house, second evening, I was a passerby who looked as if the door saw me stopped. "What is the Advanced Rebar Applications?" he asked, with reference to our name. "We are an independent external resource that creates the reinforcing steel placement drawings and materials lists," I replied. Eyebrows curled. "Rebar is? That these metal rods? "He asked." Yes, yes it is, "I answered. He turned around, as if to leave. But turned around and asked: "What is so advanced that reinforcing steel?"

It's a good question. What is reinforcing advanced? Go outside the industry would be the majority still believe that there is rebar or reinforcing steel, the same as it ever was. It's just a lot of bars in various sizes, which you place the concrete. It's a combination that is the strength of a material and marries it to the weakness of others. In this way a stronger and better building materials created, reinforced concrete. It is a system that has been used for decades. What has changed?

The first "advanced in the reinforcing steel is the material. There are new types of steel. 90 ksi to 100 ksi reinforcing steel makes its way to construction sites. This extra strength allows less material to be used in a project. This is achieved by reducing the amount of steel needed to compare the typical 60 ksi reinforcing steel and the reduced distance between the poles, due to higher tensile strength of the class. Less material can reduce the cost of a project. While the material cost can be more expensive in the beginning of these costs requires less labor for installation and use smaller quantities of material balance. Rebar is the availability of mechanical joints. This can eliminate the knee joints, or that existing structures can be used to strengthen steel, in order to expand the tree or expand. There is now an anchor or terminators, acceptable anchored in smaller spaces so that the congestion of reinforcement and the work required to develop tamper bars around the traffic jams on.

Rebar is now also available in other materials as carbon steel. Stainless steel makes a change to a less corrosive materials. This means that the life cycle of a building increases and can reduce maintenance costs. We begin to see increasing use of fiber-reinforced plastic or fiberglass reinforced plastic. This material is not made of metal so there is no corrosion, and it is not magnetic. Both stainless steel and GRP can see that in certain applications such as magnetically-sensitive structures or corrosive environments such as bridges, a structure in large numbers, to a repair or replacement.

Likewise, the supplemental materials are concrete developed in recent years. Currently, there are new coatings and paste mixes that can be applied or added to a mixture. This can be done on-site mix is poured. It may, for the longer distance and the concrete flows into the molds to let fall without vibration. It can not be fixed, it can be washed and the final sum of an architectural subject. The equipment used to manipulate and move it has changed. Trump Tower in Chicago was built of concrete cast on site. In this way, the newer concrete pumps, the materials must be attributed to travel hundreds of feet in the air. A task that until a few years ago was not possible, if not impossible.

The other "advanced in welded" is involved in the process. Like all industries has changed the use of computers in the industry. The material can now start to practice until the final editing and production of the form on the website, and all steps in between. Some processors can achieve 98% return on stocks materials in his garden, waste reduction. They can run the Automated bending machine that can strip material in a bar bending machine which can produce quickly and effectively to feed complex forms. Some of these forms take several configurations to bind, which number and installation problems. The drawings have been completed in Computer Aided Drafting programs, increase accuracy and efficiency. They can be sent over the Internet to accelerate the process of revision. BIM Building Information Modeling, or starts to get into the industry. This design is the latest attempt to rationalize and open communication between owner, architect, engineer and entrepreneur. It is an attempt to identify problems in the virtual level, long before the workers on the ground trying to compensate for field conditions, negligence or lack of communication between the trade.

Taken together, reinforce "advanced". With changes in the physical materials and the latest technology to implement, reinforce, adopt today is different than yesterday. It may be the same ideas as yesterday, but with new options and concepts today, structural reinforcement of the building tomorrow and Skylines in our cities. - January 2010
