Rot-Up Method of Constructions.

Rot-Up is the abbreviation for rotation and up The concept behind Rot-Up method of construction is to perform the majority of the construction work at the ground level and then bring the structure partwise to its final position by means of rotating the structural elements about the horizontal axis on the ground. Rot-Up method of construction can be used for the construction of large span reinforced concrete barrel shell structures, steel dome arenas and reinforced concrete residential houses.

Advantages of the Rot-Up method of construction in a glance:

• Elimination of the majority of the formwork and scaffoldings
• Ease of forming and casting stiffening-sections with low weight and high moment of inertia
• Reduction of the lateral wind and earthquake forces
• Increased safety of the workers and the work conditions by performing the majority of the work at the ground level
• Improving the quality of cast concrete by reducing the thickness to be condensed
• Elimination of most of the heavy machinery such as crane and concrete pump

Large Span Concrete Shell

In order to use the Rot-Up method of construction for reinforced barrel shell structures, the shell roof and the stiffening elements are cast on the ground and then lifted to the final position by means of rotations. This method of construction, when used for the construction of reinforced concrete shell structures, practically eliminates most of the formwork, scaffolding, working at elevation and use of heavy machinery. Furthermore, it makes it possible to cast sections that have low weight and high moment of inertia.

Large Span Steel Dome Arena

Sports arenas require column-free spaces. Steel dome structures are the most effective structures for the construction of large spans. Using Rot-Up method of construction in combination with a special type of mechanical connections makes it possible to construct large span shell structures very economically and in a very short period of time.

Reinforced Concrete Residential Houses

Reinforced concrete houses are practically maintenance free and can withstand natural disasters such as fire, tornados, hurricanes and termites. The high construction cost of such houses has made it next to impossible for average income people to own them. Using Rot-Up method of construction high quality reinforced concrete houses can be constructed in a relatively short period of time at an affordable cost. In the construction process of such houses, all the sections comprising the house such as walls, roofs and floors are cast as sandwich type sections and then rotated up to the final positions by means of two 90 degree rotations.
