Post Tensioned Concrete Slabs in a Soccer Arena? Why and How?: A blog about the benefits of using Post Tensioned Concrete slabs in a soccer stadium.
The FIFA World Cup is around the corner and you are probably wondering how to make your own soccer stadium. If you are interested in having a concrete slab that is stiff, strong and resilient while reducing costs and maintaining short construction times, post tensioning should be your choice.
Post tensioning is not just for bridges. Its many benefits can also be used in stadiums and arenas, especially since those projects demand very large spans.
How does post tensioning work?
Post tensioning consists of adding high strength steel tendons inside the concrete structure to increase its capacity. The tendons are then stressed or stretched after the concrete has hardened so that it compresses the concrete and eliminates most of its internal tensile stresses. This improves its load-bearing capacity as well as its durability.
Benefits of post tensioned concrete slabs
The main advantages of using post tensioned slabs over conventional cast-in-place concrete are:
Longer spans: Its high load bearing capacity makes it possible to creat longer spans with thinner concrete slabs, which saves on material costs, construction

First some background on what post tensioned concrete is and how it differs from traditional reinforced concrete. Traditional reinforced concrete is built with steel bars or wire mesh in the middle of the concrete slab. This helps to distribute the load capacity of the slab over a larger area. These are then covered over with a layer of concrete and allowed to cure. Post Tensioned Concrete works in much the same way, but has a few key differences that change its properties considerably.
Post Tensioned Concrete slabs use a high strength cable (typically ranging from 8,000 to 12,000 psi) that is run down the center of the slab, and then anchored at both ends. Once the concrete slab has set, these cables are pulled tight using hydraulic jacks and held in place by wedges at the end of each cable. The pulling force varies depending on how much load capacity is needed in each section of the slab, but is typically around 22,000 psi. The cable adds considerable tensile strength along its length and allows for greater spans between supports compared to traditional reinforced concrete (up to 60% greater).
If you have a soccer fan, or someone who is interested in constructing a large structure for sporting events, then this blog post is for you. This blog post will briefly describe the benefits of using Post Tensioned Concrete slabs in a soccer stadium.
There are many different types of concrete slabs to choose from when designing a soccer arena. The most common type will be the traditional slab that consists of cast-in-place concrete with reinforcing steel bars (rebar). Alternatively, there are precast concrete panels that may have connections with cast-in-place topping and rebar. Lastly, there are Post Tensioned Concrete slabs, which consist of cast-in-place concrete with high strength steel cables (also known as tendons).
The main reason to use Post Tensioned Concrete slabs in a soccer stadium is due to its ability to span long distances without the use of deep beams or columns. This allows the stadium seating area to have more uninterrupted views and provide more space for concession stands and other amenities. Other benefits include increased stability under load, increased serviceability deflections, increased durability and resistance to cracking, reduced maintenance costs and longer service life. All these benefits help to save on construction costs by eliminating costly repairs over the
In this article, we will explore the benefits of using post tensioned concrete slabs in a soccer stadium. We will also look at the history behind this method and how it has been applied in various arenas.
Most of us have heard about post tensioning before; however, few know exactly what it is. Post tensioning is a way to build concrete structures that uses steel cables or tendons which are tensioned after the concrete has hardened. This allows for greater control over the finished product because there is less cracking and distortion due to shrinkage as well as improved uniformity throughout the entire structure. It has many advantages over traditional methods like pre-stressing or reinforced concrete construction since it requires less materials while providing much stronger results with less risk involved during installation/construction time frames.
The use of post tensioned concrete slabs in a soccer stadium can be traced back to when post-tensioning was first used in 1867 by William Pole of England (hence “post” meaning “after”). During World War I, engineers used PT systems extensively to build bridges across rivers where there was no suitable land available for traditional methods such as piling or cantilevering due to heavy shelling by enemy forces.”Post-Tensioning” was invented by Henry
Post tensioned concrete slabs are a great option for a soccer stadium. This is because post tensioned concrete can span long distances without needing additional columns, which would obstruct the view of the spectators. In addition to spanning long distances, post tensioned concrete allows for thinner slabs which can reduce the height of the stadium, allowing more people to be seated closer to the pitch. Using post tensioned concrete also provides other benefits such as reduced cracking and better control of deflection. Post tensioning has been used in many soccer stadiums around the world and will continue to be used due to its many benefits.
The first step in building a post tensioned concrete slab is to put plastic chairs on top of the ground. These chairs hold up rods that will be used for stressing during construction. After this is complete, rebar mats are placed on top of the chairs, and these mats are tied together using wire ties. Next, formwork is installed over the rebar mats. Formwork consists of large wooden boards that help give the slab its shape and strength during construction.
After formwork has been installed, fresh concrete is poured into it and allowed to cure. Once the concrete has cured for about 28 days, the stressing process can begin. First, stressing cables are threaded
An arena, which is normally defined as a covered area for sports or entertainment, is generally open to the outside air on at least one side. The seating capacity ranges from 7,000 to 80,000 people and can be temporary or permanent. The arena is typically circular or oval in shape.
Soccer arenas are often found in warm climates where large amounts of open air ventilation (windows) are included. This creates an environment that is conducive to spectator comfort and player performance. Post tensioned concrete allows for more open air ventilation when compared to standard reinforced concrete design because the post tensioning strands act as high strength tendons that do not require shear steel to transfer the loads of the structure into the foundation.
Post tensioning provides a monolithic design with less concrete and less reinforcement steel than traditional reinforced concrete design. The post-tensioned slab-on-ground system has been used successfully for many years in parking garages, warehouses and other commercial projects. Post-tensioning allows for a thinner slab and provides a greater span capability than any other construction material.
The post tensioning process includes placement of plastic ducts within the formwork prior to pouring the concrete. The ducts act as conduits for the high strength post tensioning strands that are
I work for LJB Inc. a Civil Engineering firm based in Dayton, Ohio. I am currently working on the design of a new soccer stadium for the University of Cincinnati Men’s and Women’s Soccer teams. The stadium will be located on the campus of UC and will have a seating capacity of 4,000 spectators. The playing surface is natural grass with an underground drainage system.
The concrete structure consists of precast concrete bleachers, post tensioned concrete slabs and cast in place concrete stairs. The PT slabs are a great choice over steel or wood in this application due to their durability, ease of maintenance and strength to weight ratio.
As mentioned above, the seating is primarily precast concrete bleachers with post tensioned concrete slabs supporting them over the playing surface area. This was done for several reasons including:
1. Reduced construction schedule – By using PT slabs structural erection time was minimized since there was no need to erect structural steel or form and pour lumber boardwalk decks prior to pouring the concrete slab
2. Strength & durability – PT slabs can withstand heavy loads without deflection while providing a durable long lasting structure
3. Cost savings – PT slabs provide cost savings by reducing labor costs associated with forming lumber decks
