Integration lines and Constraint lines are efficient tools when modeling and designing walls and slabs and are presented in a two part webinar series.

In Part 1 we discuss the benefits of using integration lines to derive the resultant shear, axial or moment forces at areas of interest in your structural model. Unlike adding additional nodes or structural members, the integration lines do not affect the stiffness or mass of the structure when analyzing and can be added during modeling or after an analysis, on-the-fly. Topics Covered:

• Wall Integration Lines
• Strip Integration Lines
• Assembled Wall Lines (Piers)

In Part 2 of this two-part webinar series, we discuss how and why you should use the constraint line tool in S-FRAME Analysis. These constraint lines provide an efficient method for defining the connection between panels and walls. Topics Covered:

• Rigid Constraint Lines – use for connecting shell elements that may not share joints to one another.
• Pinned Constraint Lines – allows for moment release between shell elements.
• Hysteretic Constraint Line – allows for an inelastic connection stiffness to be defined between shell elements.

Understanding Pile Design capabilities in S-FOUNDATION.

Pile Support Foundation design presents helpful tips and tricks for

• accurate pile cap modeling
• soil strata definitions
• and a clear understanding of your analysis results

Knowing how to determine connection design forces across joints in your structural model enables the engineer to effectively communicate the necessary information to the connection detailer.
​
This presentation describes the Pass-Through Force calculation tools in S-FRAME Analysis. These tools allow engineers to manually, or automatically, determine which members are contributing forces to a connection, and observe the connection design forces.

We will walk through an example showing how to obtain these connection design forces in an S-FRAME model, and also verify these forces by comparing the S-FRAME results to published hand calculations.​

Lateral torsional buckling (LTB) is a key failure mode that typically governs the capacity of long span laterally unsupported beams. Given that LTB provisions in design standards have several limitations, a family of advanced beam buckling elements was developed at the University of Ottawa to determine the elastic critical moments for beams under general loading and boundary conditions. The solutions capture span interaction, load height effects, bracing types, bracing height effects, etc., while keeping the modelling effort to a minimum. Some of these advanced elements were recently implemented into an advanced LTB design module in S-Steel and integrated with LTB design provisions to characterize the factored resistance of beams. During the presentation we will

• Present an overview of LTB fundamentals and identify limitations of standard provisions
• Discuss the basis of the new S-Steel module
• Compare the predictions of the new S-Steel module against standard-based solutions, and
• Illustrate the capability of the new S-Steel module to conduct designs and explore What-If scenarios.

This presentation concludes with a Q+A opportunity for attendees.

Presenter:
Dr. Magdi Mohareb, P. Eng., Professor of Structural Engineering, Department of Civil Engineering, University of Ottawa, Ontario CA
