=== Deflection calculation timber Eurocode ===
The deflection calculation according to the Eurocode has several parts:


* '''w-inst :''' Elastic deflection according with the standard elastic modulus of the timber type due to the dead load.
* '''w-creep''': Deflection due to creep. 1. Deflection due to load combination SLS 6.16b with normal elastic modulus. 2. Deflection due to combination 6.16b with elastic modulus is Emean/(1+kdef). w-creep=2-1.
* '''w-k:''' Deflection due to the 6.14 combination(SLS).
* '''w-fin''': w-k  +  w-creep
* '''w-add''': w-k  +  w-creep  -  w-inst
=== Deflection calculation concrete Eurocode ===
The physic non-linear properties are used in the calculation using the M-kappa diagram. The stiffness differs per point in the beam due to reinforcement/cracked/non-cracked.
The beam is separated into parts. For each part the non-linear properties are calculated based on the reinforcement and M-kappa diagram. Separate calculation are made for the ULS and SLS.

'''w-inst :''' Elastic deflection according with the standard elastic modulus of the timber type due to the dead load.(short term EI)
'''w-creep''': Deflection due to creep. 1. Deflection due to load combination SLS 6.16b with short term EI. 2. Deflection due to combination 6.16b with elastic modulus is long term EI. w-creep = w;qp;long  -  w;qp;short.
'''w-k:''' Deflection due to the 6.14 combination(SLS).
'''w-fin''': w-k  +  w-creep
'''w-add''': w-k  +  w-creep  -  w-inst
