Beam Library

 

The beam library calculates automatically the mass and area moment of inertia which is determined by the cross section area.

 

Figure 1  Beam property page [Library]

 

Library supports 8 types of cross section area such as Circular, Elliptical, Rectangular, Thin-Wall Tube, Thick-Wall Tube, Hollow Rectangular, I-Beam, and T-Beam.

How to Use Beam Library

 

Figure 18  Process when using Library data

 

1.  Select a beam cross section type among Library in Beam property page.

2.  Click Properties.

3.  Define Geometry Property and click Recalculate (If the user wants to calculate Shear Area Raito values when recalculating using Library data, please check Poisson ratio).

     And then data of the area moment of inertia and the area of cross section is calculated using Library data.

     If the user wants to input the user-defined data, input the values directly.

4.  Click Close.
