S3D.rc_design (deprecated)

warning

This namespace is now deprecated. Please use S3D.design instead.

The S3D.rc_design namespace provides functions that allow beam and column design for reinforced concrete to various design standards.

S3D.rc_design.getInput#

Generates and returns the RC member design input object (referred to as design_obj below) that will feed into the concrete design check calculations. The design_obj can then be adjusted to use preferred design parameters, reinforcement, materials or loads.

KeyTypeAcceptsDescription
s3d_modelobjectA s3d_model objectAn object containing information that represents a Structural 3D model.
design_codestringACI_318,

Sample input for the S3D.rc_design.getInput function#

{
"function": "S3D.rc_design.getInput",
"arguments": {
"s3d_model": MODEL_OBJECT,
"design_code": "ACI_318"
}
}

Sample response for the S3D.rc_design.getInput function#

The response will give a design_obj object that can be passed into S3D.rc_design.check. It provides all necessary input to run a member design check.

S3D.rc_design.check#

Run an RC design check from US, Australian, European, Canadian and British standards. The API will calculate all member capacities, utility ratios and generate summary and in-depth calculation reports.

Custom sections#

SkyCiv supports custom sections and reinforcement checks via SkyCiv's General Section Designer. Use S3D.SB.runGSD to run custom as seen in the image below.
