Comprehensive Deflection Methods

 SLABS 2009 can be used to evaluate short-term (instant), incremental and total long-term deflections by several alternative methods using cracked section properties of the beams and the slab.  The effective moment of inertia (Ieff) of the cracked sections of the slab is evaluated at each nodal point in two orthogonal directions independently, following the orientation of the reinforcing bars entered by the user.

 

It evaluates the long-term by three alternative methods:

1. Kcs  ( increased load factors, AS3600 )
2. Age-adjusted Effective Modulus Method  (AEMM)
3. Eurocode 2 approach (EC2)

If the user chooses to analyse a model incorporating all 3 methods, the model will only need to be solved once with necessary calculations automatically performed by the software.
