The most important assumptions are as follows:

Usage class 1
Permanent load g_k without cross-laminated timber; this has already been taken into account in the calculation
Load capacity: cat. A (residential) and B (offices) ψ0 = 0.7 [-], ψ1 = 0.5 [-] and ψ2 = 0.3 [-]
Fire rating according to DIN EN 1995-1-2/NA and a burn rate of β₀ = 0.65 mm/min
Verification of vibration according to Hamm/Richter with
- Lehr’s damping ratio of 4 %
- b = 1.2* l
- cement screed with 6.0 cm und einem E_module of 25,000 N/mm²
- structural requirements must be considered
Deflection analysis with k_def of 0.8 [-] and the following limits
- w_inst = l/300
- w_net,fin = l/300
- w_fin = l/200
The pre-structural design table does not replace a static calculation
