57. Structural System Representation
Stable section ID: S05-CON-007-SECTION-58 · 51 content blocks
A Structural System shall represent the complete network of Components and Connections responsible for resisting and transferring loads.
The Structural System declaration shall include:
System ID;
system classification;
structural Components;
Nodes;
structural Connections;
supports;
load paths;
diaphragms;
bracing;
stability systems;
movement joints;
temporary states;
analysis models;
applicable Profiles;
capacity and demand evidence.
Example:
structural_system Primary_Structural_System {
id: "s05:structural-system:primary";
- members: [
- @Column_C01,
- @Beam_B01,
- @Brace_BR01
];
- nodes: [
- @Node_N01,
- @Node_N02
];
- connections: [
- @Beam_B01_to_Node_N01,
- @Column_C01_to_Node_N01
];
analysis_model: @Structural_Model_Rev03;
engineering_profile: @US_NJ_Light_Frame_Profile;
}
Structural topology shall identify how gravity, lateral, uplift, accidental, and temporary construction actions reach their supports.
Load paths shall be explicit:
load_path Roof_Gravity_Path {
from: @Roof_Panel_RP01;
- through: [
- @Beam_B01,
- @Node_N01,
- @Column_C01
];
to: @Foundation_F01;
actions: [gravity];
}
BDL shall distinguish physical, analytical, and simplified topology.
Changes to a structural Component, Connection, Node, support, or material shall trigger analysis and validation of affected load paths.
Temporary erection states shall be modeled where the completed structural system is not stable during intermediate assembly.
