A limit states design approach for onshore pipelines has been developed with reliability-based design rules for geotechnical loads. In consideration of the modelling complexity of the soil movement mechanisms and pipe-soil interaction, and to allow for flexibility to incorporate future model developments, the design rule formation is directly based on the distribution parameters of the strain demand and capacity of the pipeline.
Working as part of a joint industry project, we used the structural reliability-based approach to develop the strain demand and strain capacity parameters required to apply the design rules. The paper presents a case study focused on slope creep to demonstrate this approach, as well as general guidance for:
- Seismic loads
- Frost heave and thaw settlement
Dr. Smitha Koduru is presenting the results of this project at the upcoming International Pipeline Conference in Calgary, Alberta on September 26, 2018 at 10:30 a.m. to 12:00 p.m. The presentation will be in Telus MacLeod E4. You will learn about how to develop the strain demand and capacity distributions required to apply reliability-based design rules for geotechnical loads.
The entire paper – Development of Strain Demand and Capacity Distributions to use in Limit States Design for Geotechnical Loads - is available through the 2018 International Pipeline Conference.
