Starting with version 9, for built up members loaded on the weak axis (d-face), the program used the sum of the thicknesses of the plies as the depth used for determination of section modulus Sy in the expression for bending moment stress fb from NDS 3.3.2 , and for the moment of inertia Iy in the stiffness EI used in deflection calculations. However, this assumes that the plies are rigidly connected, as with glue. As full composite action cannot be achieved by fastening members with bolts or nails, the program once again uses the single ply thickness to calculate S and I for each ply, then sum these values for a composite S and I to determine fb and EI, respectively This results in a greater bending stresses and deflections than the program had been calculating.
The constant K for shear deflection calculations was the value in lbs. multiplied by a factor that converts metric values in Newtons to imperial values in lbs, therefore the constant K was smaller than it should be by a factor 4.43, and total deflection roughly twice what it should be.
The incorrect K value was also displayed in Database Editor. Both problems have been corrected.
The program now records the version of the program used to save a project file and shows it in the About Sizer box when the file is opened. This feature is primarily used internally at WoodWorks for diagnostics.
Starting with version 10 of the program, the initial focus for beam view was set to the Description rather than the Span input. As many users are used to entering spans first, they typed the span length numbers into the Description field instead. This has been corrected and the initial focus is back on the spans.
