Slovak National Soccer Stadium

The National Football Stadium or „Tehelné pole“ is our   biggiest and  greatiest investment for   modernising football stadiums in Slovakia. The stadium is built in a location of previous   stadium ( legendary Tehelné pole), and   it  retains continuity of the enviroment. This project meets the highest  criteria for the standards for the UEFA  category 4^th . There will be  more floor space for VIP zones , SKY-boxes and conference rooms. Underneath the stadium  will allow for  more than 1,000 parking spaces. The design  incorporates     the most advanced methods of the  membrane grandstand roofing . It is  designed intuitively and divided into the four cardinal points:

• The North Grandstand
• The East Grandstand
• The West Grandstand
• The South Grandstand

From a construction standpoint the steel construction of the South and East  Grandstands are  indentical.
The  construction of the North Grandstand is  lower  to improve lighting on the neighbouring  buildings.
The West Grandstand is lying on the  bearing reinforced concrete roof construction.
A cantilever is incorporated around all grandstands for shade and weather protection.
The baseline statics schemes for all grandstands  is console.
From the statics  and architecural  point of view  only  The East Grandstand and  The South Grandstand have the same shapes.
The linings of cantilevers  differs for each grandstand.

• The North Grandstand: 23,30 m,
• The East Grandstand: 29,00 m,
• The West  Grandstand :   24,38 m,
• The South Grandstand 29,00 m.

The cantilevers are designed  as truss grider which are anchored  into the reinforced construction.
The North Grandstand cantilevers are adjoined to the steel frame anchored to the beared reinforced concrete components of the grandstands.
The back part of the construction  creates cantilever and tension rod  for the external cladding.
The cantilevers on the West Grandstand are joined to the two-span steel frame, which is anchored to the roof beared  reinforced fragments.
The cantilevers on The East Grandstand and  The South Grandstand  are joined  to the steel column.
In the back part of the constructions is tension truss   balancing  system  which is designed from steel horizontal cantilever and system of two  tension  truss.
In longitudal course the stability of the roof construction all grandstands is secured by trussed bracing.
Construction  membranes of the  upper bars with konvex curve line of the membranes are constructived with  reserved so they would avoid the contact of  membranes which could cause problems with water leakage.
The front part of roofing with length L=12m  is designed to add more  lighting.
This construction is designed with rolled section   IPE and jakle steel section.  The polycarbonate plates (th = 10mm)  will be sitting on them.
The upper bars diagonal tying brackets  are designed from jakle steel section.
Diagonals, verticals and  buttom  horizontal parts of  truss are designed from seamless steel tube.
In assembly  phase, the vertical diagonals   for longitudal tension truss  L=8,15m  secure stability of the cantilevers, and   especially  secure the reinforcement of function from  horizontal   action of  the membranes.
The steel constructions are made of two parts and put together on site. It will be anchored to already installed plates or screws.
The whole project was unique and complicated considering its shape options and complexity of construction.
