the following sections from the pci design handbook include interaction curves, load tables, and section properties for various precast concrete components. you can access tables from previous editions of the handbook as well as the current edition. for additional explanations on using these tables, refer to the respective handbook editions.
as an added benefit, the hollow core slabs will eliminate the need to drill the slab for electrical and mechanical runs. primarily used as floor or roof deck systems, hollow core slabs also have applications as wall panels, spandrel members and bridge deck units. vcon uses a higher slump concrete system.
hollow core pre-cast concrete slabs. primarily used as floor or roof deck systems, hollow core slabs also have applications as pedestrian bridge deck units. hollow core is the product of choice in buildings requiring sound barriers between floors.
the existing standard bridge designs, which are contained in the ministry of works publication highway bridges standard plans, also known as the red book , cover the following beam shapes and span ranges: precast pre-tensioned single circular hollow core deck units 8 m to 14 m spans

this technique is usually found in concrete beams, spandrels, columns, single and double tees, wall panels, segmental bridge units, bulb-tee girders, i-beam girders, flat slabs and hollow-core slabs. during post-tensioning of concrete, the compression is added following the curing process.
fig 6: average mobility, hollow core bridge deck, illinois. figure 5 is the underside view of the deck, showing the keyed beams. figure 6 is the contour plot of average mobility for the deck, with very high mobility along the southern transverse bolt, as opposed to relatively low mobility along the northern bolt line. this indicates that the

santosh kulkarni sir has already mentioned it , the term deck slab is related to bridge engineering. basically the deck slab is the part of structures which is constructed over the girders and being used by the vehicles to cross over the bridge. i
structural precast. insulated wall panels hollow core slabs precast bridge girders directly support the bridge deck and are more economical than steel girders. the durable, maintenance-free bridge product is prestressed to achieve favorable span-to-depth ratios.
hollowcore commercial applications hollowcore commercial applications . massive strength and proven durability. hollowcore gets its strength from pretensioned steel strands that are embedded in high strength concrete. continuous voids in the planks reduce their overall weight and help keep building costs in check. bridge deck units . product
load-span tables. the above load-span table takes into account self weight, finishes, imposed load, service/ultimate conditions, deflection and natural frequency. they are given as a guide only, please contact us on 01636 for further advice.
