In GB 50017-2017, members are divided into three categories: flexural members, axially loaded members, and tension (compression)+ bending members. You can force some components to be any of the above types. In this case, the program will check according to the type specified regardless of the geometry or stress. You can also let the program judge automatically. When the program judges automatically, there are two judging principles: according to the geometric position or according to the force characteristics. If you do not specify the component type, the default setting of the program is automatic judgment. The classification principles of various components are described below.
- According to the geometric
The flexural member member is located in the horizontal plane of XZ The axial force member member is defined as the member truss Tension (compression) + bending member other members
- According to the actual
stress situation of members
The flexural member member with axial force = zero The axial force member member with bending moment = zero Tension (compression) + bending member other members
The flexural members are beam members. The judgment principle used in the program is: if the vertical coordinate difference between the two ends of the component is zero, it is regarded as a flexural member; if the axial force of the component is zero, it is regarded as a flexural member. The clause of flexural member shall be used in code inspection.
Axially Loaded Members
The axially loaded members are column members or truss members. The judgment principle adopted in the program is: when judging by geometry, the axial force member will not be generated; if the bending moment of the member is zero, that is, it is not subjected to bending moment, it is regarded as the axial force member. In the standard inspection, the axial force member clause is used.
Tension (Compression) Bending Member
In addition to the above-mentioned flexural members and axially loaded members, all other members in geometric or stress states are regarded as tension (compression) bending members in the program. In the standard inspection, the terms of tension bending and compression bending members are used.
