Define Effective Beam
Define the effective beam.
This function is used when analyzing/designing two-way slab systems without beams using the effective beam width method (EBWM).
When an effective beam is installed and the EBWM is used, the effective beam acts on the lateral load and only the meshed slab acts on the gravity load.
If effective beams are installed and analysis is performed using the finite element method (FEM), effective beams are regarded as non-existent and only meshed slabs are used for analysis and design.
Analysis method determination options can be set in Analysis > Analysis Control > Design Analysis Control.
From the Main Menu select Node/Element > Flat/Plate Structure > Effective Beam > Define Effective Beam.

1. Name: Enter
the name of
Effective Beam. 3. i-Node / Width(Left), Width(Right) - Enter the left/right width based on the center line from the i-end node to the j-node. (Enter a real number greater than 0) 4.i-Node / Width(Left), Width(Right) - Enter the left/right width based on the center line from the i-end node to the j-node.(Enter a real number greater than 0) It can be set different widths on the left and right, or set effective beams with different widths at the i-end and j-end
