Secondary steel beam PMM ratio not satisfied.

This message is created by specifying the element name and floor on which it is located at the beginning of the report.

For example,

SB001 BASE STORY PMM ratio not provided.

In steel element design, the design ratio under the influence of axial force and biaxial bending (PMM ratio) is made in accordance with the Design, Calculation and Construction Principles of Steel Structures (GKT and YDKT), AISC 360-16 (ASD and LRFD) or EN 1993-1-1 regulations. . According to the Design, Calculation and Construction Principles of Steel Structures (GKT and YDKT), the calculation of axial force and biaxial bending interaction equations is stated below.

• The PMM ratio value must be less than 1.

Possible Solutions:

• The bending capacity of the secondary beam section can be increased by defining composite flooring on the secondary beams . In this way, a composite beam design is made for the secondary beams. This title can be examined for the warning that composite beam strength is not provided .

• The effects of incoming loads can be reduced by reducing secondary beam distances.

• Sub-beam cross-section size can be increased.
