In the last decade ultra-high-performance concrete (UHPC) has significantly attracted the interest of researchers and practitioners due to its material performance and its potential for innovative practical applications. It has become one of the most influential materials in the construction industry in the twenty-first century. After years of innovations in material, structural and architectural design what are the current UHPC hot topics? This session will invite national and international research groups, material suppliers and contractors to share their knowledge of hot topics of UHPC.
Learning Objectives:
(1) Define architectural UHPC;
(2) List potential applications of UHPC overlays;
(3) Discuss the opportunity of using sprayed UHPC;
(4) Summarize field implementation of UHPC for beam end repair.

The panel will discuss the different points of view and specific challenges they face to maintain the balance. The panel, in addition to sharing their experiences, will discuss a variety of solutions and techniques to help other tackle their work life balance challenges.
Learning Objectives:
(1) Describe what work life balance means;
(2) Summarize challenges and problems that may affect work life balance;
(3) Identify strategies to manage your time better to achieve a good work life balance;

12:00 PM - 1:00 PM

Speaker: David Moody
Title: Changing Directions is Not the Same as Quitting
So often we are told to chase our passions. There is a difference between our passion and what we are truly good at doing. Moody thought he would be the next Frank Lloyd Wright, got his 5-year professional degree in architecture and started pursuing that dream. Then, Moody took a construction filed assignment and realized he would be just an average architect, but he could be a really good builder. Moody will discuss that pivot in his life and what it is like to be an entrepreneur.

Learning Objectives:
(1) Understand the basis of AASHTO live load distribution factors and simplification options for girder bridges;
(2) Determine AASHTO knowledge gaps and ways to plug them for girder bridges;
(3) Consider real-life implications of design, evaluation, construction, and maintenance issues for girder bridges;
(4) Identify advanced numerical analysis or experimental load testing techniques used to determine live load distribution for girder bridges.
