Designing

Calculations

The SL-Deck will be dimensioned and calculated according to the Eurocode 2 (DS/EN 1992-1-1) to each individual project.

Concrete quality

The self compacting concrete SCC has the compression strength fck = 55 MPa.

The light-weight concrete has the compression strength fck = 3 MPa.

Reinforcement

Prestressed steel reinforcement is used according to the below table:

Standard Strength Diameter Maximum tension Typical 0,1 % tension
Pr EN10138-3 1860 MPa 12,5 mm ≥ 1860 MPa ≥ 1634 MPa

Non-stressed reinforcement is used according to the below table:

Standard Standard dimensions Class according to
EN1992-1-1
Typical pretension force
DS/EN 10080 6, 8, 10, 12, 14, 16, 20 mm B 550 MPa

Quality Control

The production in Denmark by Perstrup Beton Industri is monitored by Dancert and the SL-Deck is certified according to DS/EN 13224 certificate nr. 1073-CPD-B087-03

Environmental classes

The standard SL-Deck is designed to fulfill the requirements of a passive environment. However, it is possible to produce the SL-Deck to fulfill the requirements of other environmental classes, including especially aggressive environmental classes for parking facilities etc.

Concentrated loads

Due to the design of the standard SL-Deck comprising zones of primary light-weight concrete and others of primary stronger concrete, the load capacity for single point loads varies across the deck. Zones comprised primarily of light-weight concrete have a limited capacity for single point loads. However, it is possible to place massive zones wherever they are needed if predefined by the customer. In addition, additional normal reinforcement can be placed in these areas in order to further increase the capacity for concentrated loads.

Deflection

The load-carrying capacity tables for the SL-Deck indicate a calculated deflection. Due to contraction of the prestressed steel wires the deflection can vary depending on the length of the slab, production and curing conditions can also impact the actual deflection of each slab.

Difference in deflections across several slabs can be adjusted by blocking up slab or by applying load to a slab after installation but before the grout is applied and has gained the necessary strength.

Supporting areas

The standard SL-deck is made with a vertical end, but it can be modified to have skewed ends in the vertical direction allowing for a half V shape making the placement of reinforcement between slaps easier.

The minimum depth of supporting walls or beams carrying the SL-Deck must be 55 mm as a minimum. The directions below should be followed when planning to install SL-Decks:

Slab Length (L) Supporting depth
L < 7 m 65 mm
7 m < L < 14 m 80 mm
L > 14 m 90 mm
