Full Session without Abstracts
Sponsoring Committees: Structural Members (TAC Metals) and Cold-Formed Members (TAC Metals)
Format: Innovative Executive Session (IES)
The session covers design issues that have perplexed structural engineers including stiffness demand of braces used to control buckling of multiple parallel members, effect of bracing connection stiffness on the buckling strength, stability design of a column subjected to intermediate loads, recent innovations in stability analysis of cold-formed steel members, direct modelling of inelastic behavior of hot-rolled steel frames, connection stability and performance based design of cold-formed steel frames, among others. The session will provide structural engineers with the opportunities to clarify questions and doubts that they may have regarding the modern methods of structural analysis and design of hot-rolled and cold-formed steel frames, and to learn about recent innovations and their proper applications to the stability design of regular and irregular structures. Attendees of the session will also learn about available and acceptable methods of stability analysis and design, and their respective advantages and disadvantages. Presenters are as follows (alternating between hot-rolled and cold-formed steel structures):
