MINI SESSION: Deflection of Structures - Advancements in Methods and Reflections in Application

Monday, November 4, 2024  3:00 PM - 4:00 PM, 401

Advancements in methods used to calculate the deflection of mild and prestressed reinforced floor framing systems including creep & shrinkage and cracking behavior of prestressed concrete will be presented. Also, built examples using methods in ACI 435's document will be presented. The combined topics will foster communication between researchers and practicing engineers.

Learning Objectives:
(1) Learn about key factors affecting deflection performance of slab and beam systems;
(2) Learn new methods of deflection calculations including creep, shrinkage, and cracking of prestressed members;
(3) Learn about real-world application of ACI 435's recommendations including how it compares to project surveyed results;
(4) Learn about how construction sequence such as shoring / reshoring can affect the deflection of slab and beam systems.

Description: NOTE TO REVIEWER: We would like this to be part of and precede our ACI 435 meeting that occurs 3-6pm. We would be ok giving the slot of 3-4p at the start of the meeting to do this so it wouldn't require an extra room. We are really just asking it be listed as a mini-session in the conference schedule/app.
