Concrete Slab Span Table

The load tables present the superimposed live load capacity of the various members at various spans. With 15 reinforcement the limit is 14 and corresponding limits are specified for continuous beams flat slabs and cantilevers.

Density of lightweight concrete. However values given in the tables are intended for preliminary member selections not final designs.

At first sight this looks refreshingly simple. The following table presents limits on slab spaneffective depth ratio which can be used to work out the correct thickness for slabs directly at the start of design without any need for later adjustments. Additional unit depths are available on request up to maximum of 175mm.

The basis of the load capacities is ACI 318-05 which is the reference document for. 6 Cellular Deck 1616 GA Single Span w 3 LW Concrete. One shore support is required at mid span.

When the supporting apron bends more than the concrete slab can take it will break. Yes the concrete slab will bend too.

They have been calculated in. Prestressed and Reinforced Wall Panels. Download specifications about Spancrete hollowcore for use in the preparation of specifications for a particular project.

Effective Span of Slab The effective span of a simply supported slab shall be taken as. Load tables are provided for Spancrete hollowcore plank beams and double tees. DL LL 305 100 1305 psf.

The 34 deflection criteria may be impractical for profiles deeper than 3. Spandepth ratios for reinforced concrete slab design to BS8110. Spans that exceed this are shown in grey.

Open the catalog to page 1. The spans indicated below have not been limited to 50 x unit depth usually used to minimise the dynamic movement in the planks. However recently there is a preference for large floor areas with column-free space and spans.

These values assume that the safe superimposed load is composed of 60 dead load and 40 live load. 150mm planks 750m 200mm planks 1000m 250mm planks 1250m. Capacities are in conformance with the American Concrete Institute Building Code Requirements for Structural Concrete ACI 318-05.

More like a given board will bend 18 inch with 100 pounds and 28 inch at 200 pounds and 38 inch at 300 pounds. 742 Table 74N gives spandepth limits for beams and slabs with a service tensile stress f s of 310Nmm². Hollowcore Load Span Table.

Supporting 3 of lightweight concrete cover the unshored span can be increased by 4-7 or 20 which is significant. The Table shows typically supported effective spans in metres. Density of normal weight concrete.
