II SPECIFIC CONDITIONS

1 Definition of the product and intended use

The construction products are prefabricated cable net consisting of cables (net cables, lacing cables) made of stainless steel and the appropriate ferrules for connection and deviation of the cables as well as border cables or frames made of tubular sections as surround of the cable nets (see Annex 1). Deviating and anchoring of the border cables is done by appropriate components (shackles, eye bolts, eye nuts, end connectors). The opening angle of the cable net mesh is 60°. The mesh width is variable and is inbetween 35 mm and 100 mm depending on the cable diameter. The installation occurs either as vertical cable net (e.g. railings) or horizontal cable net.

The planning requirements are specified in annex 1 to 13. In addition, all data relating to calculation (chapter 3.2) and execution (chapter 3.3) must be observed.

3.2 Calculation

3.2.1 General

The verification concept stipulated in DIN EN 1993-1-1110 shall be applicable to the verification of rope net load-bearing safety.

The verification of the cable net systems at ultimate limit state is fulfilled if the loading of the cables, border cables, net ferrules, shackles, eye bolts and eye nuts does not exceed the design values of resistance given in section 3.2.3 – 3.2.5.

For the verification of the ultimate limit state of eye bolts and eye nuts it is considered that a linear verification of interaction in case of combined loadings of tension and shear force shall be proved. The verification at ultimate limit state takes into account if eye bolts and eye nuts are additionally imposed by bending loads.

3.2.2 Modulus of elasticity EQ of the cables (net cables, lacing cables) and border cables

The following values shall apply:

Wire rope EQ: 90 kN/mm²

Spiral strand EQ: 130 kN/mm²

3.2.3 Tension resistance of the cables and border cables

The ultimate tension resistance FRd of the cables and border cables shall be determined as follows:

FR,d = Fuk / (1,5 · ˠR) where: Fuk = Fmin · ke

characteristic value of the calculative breaking resistance of the cables Fmin minimum breaking load according to Annex 6, chart 3 and 5 ke strand factor, loss factor according to Annex 6 ˠR = 1,0 The characteristic value of the ultimate tension resistance applies to the cable respectively border cable including the appropriate ferrules respectively end connector.

3.2.4 Sliding force of the net ferrules

The difference force between two net cables placed side by side and connected by net ferrules is less than the design value of the sliding force of the net ferrules. For the characteristic value of the sliding force GR,d of the net ferrules the following applies:

Cable net systems with stainless steel ferrules of type CXS are intended for the use in structures with predominantly static loads only.

3.2.5 Load-bearing capacity of shackles, eye nuts and eye bolts

For the characteristic values of the tension resistance NR,d of the shackles, eye nuts and eye bolts the following applies:

For the verification of the ultimate limit state of eye bolts and eye nuts it is considered that a linear verification of interaction in case of combined loadings of tension and shear force shall be proved. The design value of the shear force shall be determined according to EN 1993-1-496 and chapter 3.2.1.

3.2.6 Verification as fall protection

The cable net systems may be used without an additional verification of fall-protection subject to compliance with the conditions specified in Annexes 7 until 11.

3.3 Execution

The installation is solely carried out according to the manufacturer's instructions. The manufacturer hands over the assembly instructions to the assembler.
