Due to their architectural-structural and economic advantages in comparison with steel structure system and reinforced concrete, pre-stressed system is a good choice for trade and residential buildings, hospitals, towers and mass housing.
The most important advantages of pre-stressed constructions are as following:
Comparison Parameter | Steel Structures | Concrete Structures | |
Reinforced | Pre-Stressed | ||
Length of spans | Average | Lowest | Highest |
Useful space area | Average | Lowest | Highest |
Beams hanger | Average | Highest | Lowest |
Ceiling thickness | Average | Highest | Lowest |
Architectural compatibility | Higher | Lower | Highest |
Rust and corrosion danger | Highest | Lower | Lowest |
Damage in fire | Highest | Lower | Lowest |
Structures lifelong | Lower | Higher | Highest |
Constructing more floors up to an authorized height | Lower | Lowest | Highest |
Increasing construction projects’ profitabilityby increasing number of parking lots | Lower | Lowest | Highest |
Exact control of deflection, deformation and fraction in the structure | Worst | Worse | Best |
Better laying of construction pipes | Lower | Lowest | Highest |
Being used in irregular and curve-shaped plans | Lowest | Lower | Highest |
Making bigger openings in irregular shapes in the ceiling | Lower | Lowest | Highest |
