INCO 70.4

Product catalog summary

Specifications:
1. Concrete Density: 2400 kp/m³
2. Structural Steel Properties: Yield Strength > 320 N/mm², Steel Quality S320GD, Tensile Strength between 370 and 480 N/mm², Modulus of Elasticity = 2.1x10⁶ daN/cm², Minimum Tensile Lengthening: 25%, Protective Coating: Z-275 Galvanized.
3. Concrete Properties: Type C-25, fck = 25 N/mm², fctk = 1.8 N/mm², Aggregate Size < Max((0.4hc), (b0/3), (Sieve C, 31.5mm)), Modulus of Elasticity = 20314.4 daN/cm².
4. Reinforcing Steel Properties: Welded mesh and round steel with high adherence, Yield strength = 500 N/mm², Distribution Mesh: Electro-welded mesh 150x150x5 mm.

Procedures:
1. Negative Reinforcement: Spacing of reinforcement bars should be 210 mm, diameter according to specified table. Single span slabs do not need negatives.
2. Laying Detail of the Reinforcements: Specific dimensions and spacing provided for effective reinforcement placement.

Standards:
1. Calculations are in accordance with Norma UNE ENV 1994-1-1: June 1995 EC Part 1-1 and UNE ENV 1994-1-2 June 1995-EC4 Part 1-2 by the Polytechnic University of Valencia.

Recommendations:
1. Fire Resistance: Composite slabs assure 30 minutes resistance (R30). For higher resistance, consider protective material, false ceilings, or additional reinforcing steel.
2. Load Combinations: ELU: Total applied load = 1.35*Permanent loads + 1.50*Live loads. ELS: Maximum Overloading = 1.00*Permanent loads + 1.00*Live loads.
3. Deflection Limits: Span < 3.5 m: Max deflection < L/350. Span > 3.5 m: Max deflection < (L/700) + 5 mm.

Data Summary:
1. Concrete Volume and Inertia: Detailed values provided for different slab depths.
2. Composite Slab Effective Values: Weight, moment of inertia, and section modulus values for different slab thicknesses and depths.
3. Load Tables: Maximum live loads for various slab depths and spans are detailed.

INCO 70.4 COLABORANTE Slab Depth (mm) LOAD TABLES Temporary supports in the middle of the span Fire Resistance: Due to the characteristics of the composite slabs, 30 minutes resistance fire (R30) is assured. In case of needing a higher resistance than this one, the following alternatives should be considered: -Protective material projected under the composite slab. -Installation of false ceilings -Additional reinforcing steel against fire, for further information about this consult with our Technical Department.
