Presenter:   Dr. Kyle Tousignant

Course Description/Overview

This module covers the design of structural welds used in HSS connections. A detailed Table of Contents is as follows.

Table of Contents

 1. Introduction to HSS Connections

a. Review of HSS Connection Terminology

b. Review of HSS Connection Limit States (per CSA S16 Clause 21.13)

2. Weld Design for HSS Connections

a. Acceptable Design Approaches (per CSA S16 Clause 13.13.4.3)

i. “Fit-for-Purpose” Approach (Clause 13.13.4.3a) (which may refer to CSA W59:23

in the forthcoming edition)

ii. Design for the Branch Resistance (Clause 13.13.4.3b)

b. Advantages and Limitations of Each Approach

3. Research

a. Background and Overview of Research (on Weld Design for HSS Connections) 

b. Reflection of the Above Research in Design Codes 

4. Design Rules in Canada

a. Information for Designers

b. Interpretation of CSA S16/W59 Requirements for Welds in HSS Connections

ii. Chapter 4 and Table 11.2 of the forthcoming edition of CSA W59 

c. Design Rules [which may be reflected in the forthcoming edition of CSA W59]

i. Transverse Plate-to-RHS T- and X-connections (under branch axial load)

ii. RHS-to-RHS T-, Y-, and X-connections (under branch axial load or bending)

iii. RHS-to-RHS Gapped K-connections (under branch axial load)

iv. RHS-to-RHS Overlapped K-connections (under branch axial load)

v. Transverse Plate-to-CHS T- and X-connections (under branch axial load)

vi. CHS-to-CHS T-, Y-, and X-connections (under branch axial load or bending)

5. Design Examples - Comparison of Accepted Design Approaches

c. Case Study on Detailing for RHS Connections 

Eligibility for CEUs

CEUs will be issued for this webinar to participants that meet the following criteria:

1. Participant must attend at least 75% of the webinar
2. CEUs are only eligible for a participant with a 90% attention rating. In order to maximize your rating the webinar must be full screen. Working on other things while the webinar is running (i.e. not full attention) minimizes your attention rating. The webinar platform automatically tracks your rating.
3. CEUs are issued to the registered contact person only (person with assigned seat)
