SSSS and BCA Two-Day Short Course

Two-Day Short Course

DESIGN OF STEEL STRUCTURES TO EUROCODE 3

Time: 9.00am to 5.00pm

Venue: BCA Academy

OBJECTIVE

This course is aimed at civil and structural engineers seeking an understanding of the general rules, main features and changes contained in Eurocode 3 Part 1-1, Part 1-5 and Part 1-8 and the accompanying Singapore National Annexes. References will also be made to the accompanying codes EC0 (Basis of Structural Design) and EC1 (Actions on Structures). The course will cover advanced design of structural component and frames, structural loading, material properties, design at the ultimate and serviceability limit states. Verification for member and frame resistance using hand calculation procedures and tabulated design data will be explained. Work examples with direct reference to the clauses in Eurocodes and Singapore national annexes will be used to illustrate the application of the code requirements. Case studies are provided to illustrate clearly the theory of structural stability and design, and how they can be applied to avoid structural collapses.Objectives

After attending the course, participants will be able to:

1. Enhance their understanding of Eurocode provisions for the design of steel structures and connections;

2. Apply design principles and standards in accordance with Eurocode 3 and Singapore

national annexes in the design of steel buildings;

3. Design structural steel frames and components in accordance with Eurocode 3 design

principles & methodology.

4. Avoid common mistakes in design with lessons learned from case studies and collapse
