Precast concrete does not burn or give off fumes in the hottest fires, and maintains its structural integrity resulting in more time to evacuate safely and extinguish the fire. Weather Patterns A precast system provides protection against hurricane-force winds; and prestressed concrete has recently been cited as being an effective barrier to damage from tornados as well.

For prestressed concrete construction, the current standard for buildings is BS8110 and for bridges BS5400, which suggest an initial prestressing force of 70% of the characteristic failing load. For ties and similar appliions in structural steel construction, the requirements of BS5950: Parts 1 and 2 apply.
Features of the prestressed concrete strand 1.High tensile strength, low relaxation, stable modulus of elasticity, stress-relieved, straight, firm connection with concrete. 2.Unbonded and bonded prestressed steel strands have good corrosion resistance and small friction of unbonded tendons, which can be easily bent into curved shapes.

Fatigue problem may arise in concrete structures which are subjected to repetitive cycling loading. Fatigue may also endanger the durability of prestressed concrete (PSC) bridges due to fatigue in
Westkon Precast prepared some of the largest concrete precast beams ever to be manufactured in Victoria for the bridge on the Breakwater Road upgrade. With several weighing in at just under 100 tonnes, it was a big job. 104 precast beams ranging from 25 to 40 metres long x 1800mm deep were moulded – some of these beams were also fitted with special post-tensioned ducts.

Structural strengthening is the process of upgrading structures to improve performance under existing loads or to increase the strength of structural meers to carry additional loads. The need for structural strengthening is commonly driven by building codes, deterioration, change in use, or deficiencies caused by design and/or construction errors.
