Input

Metric Units

(Note: All input Metric units are converted to English units for the equations below and then the output English units are converted back to Metric)

AWC 2012 ASD-LRFD Manual For Engineered Wood Construction M3.5, Bending Members Deflection:

The following is for calculating mid-span deflection of simple span uniformly loaded rectangular member.

Uniform load applied to member (w - lb/ft or N/m)

Beam span (L - ft or m)

Modulus of Elasticity of beam (E- psi or kPa)

Wet service factor (Cm)

Temperature factor (Ct)

Incising factor (Ci)

Moment of Inertia of wood member (I - in^4 or mm^4)

Output:

Deflection, Defl. =
