Design of Precast Prestressed Composite Beams Excel Sheet
The precast prestressed concrete units are erected hrst and can be used to support the formwork needed for the cast
in situ slab without additional scaffolding (or shoring),
ln addition to its contribution to the strength and stiffness of the composite member, the cast in situ slab provides an
effective means to distribute loads in the lateral direction.
The cast in situ slab can be poured continuously over the supports of precast units placed in series, thus providing
continuity to a simple span system_Pre-tensioning in plant is more cost-effective than post-tensioning on site,
Because the precast 4 prestressed concrete element is factory-produced and contains the bulk of reinforcement,
rigorous quality control and higher mechanical properties can be achieved at relatively low cost, The cast in situ
concrete slab does not need to have high mechanical properties and thus is suitable to field conditions.
