10:00 AM - 12:00 PM

Moderator: Kimberly Waggle Kramer

This session focuses on preservation and adaptive reuse as alternatives to the replacement of built structures in the pursuit of a sustainable built environment.
Learning Objectives:
(1) Review new trends and challenges of designing by preservation and adaptive reuse of structures and how concrete plays an important role on the sustainable solutions applied;
(2) Gain insight into new innovative technical approaches that greatly improve designing by preservation and adaptive reuse of structures;
(3) Discuss the key environmental benefits and energy savings when adapt and reuse design approach is implemented;
(4) Identify the social advantage of repurposing a place with valued heritage.

This session has been approved by AIA and ICC for 2 PDHs (0.2 CEUs). Please note: You must attend the live session for the entire duration to receive credit. On-demand sessions do not qualify for PDH/CEU credit.


10:00 AM - 12:00 PM

ACI 376-11/376M-11 Code Requirements for Design and Construction of Concrete Structures for the Containment of Refrigerated Liquefied Gases and Commentary was adopted by ACI in November 2011 and published in August 2013. The committee had been formed in 2003 at the request of the national Fire Prevention Association (NFPA) Technical Committee 59A on liquefied natural gas (LNG) for the purpose developing a code document that could referenced by NFPA 59A for design and construction of concrete containment structures. The scope of the Code includes not just LNG, but all refrigerated liquefied gases (RLG) where concrete is used for storage and containment. Upon completion of the first edition the committee began the work of addressing the future action items from the first edition, and other changes brought before the committee.
Learning Objectives:
(1) Discuss the design and use of concrete for storage and containment;
a. Abnormal Loads: Fire, blast, liquid spill, thermal shock and linear/non-linear FEM calculations
b. Abnormal Loads: Seismic
c. Design and construction of concrete storage tanks
(2) Describe thermal corner protection;
(3) List the changes to the 376 Code since the first edition;
(4) Review committee plans for future code changes and code-related technical notes.

10:00 AM - 12:00 PM

Moderator: Pericles C Stivaros

This session will be of interest to design engineers, contractors, formwork engineers and manufacturers, and others interested in concrete formwork construction practices. Attendees will have the opportunity to learn from design and construction formwork successes as well as unsuccessful projects and learn about the various types of formwork, formwork economics, formwork troubleshooting, tolerances, and safety issues during formwork operations. Be sure to attend this session to learn about the various types of forming systems.
Learning Objectives:
(1) Describe how to economize on formwork (considering that the cost of formwork is approximately 35% to 60% of the concrete cost);
(2) Examine construction tolerances relating to formwork installation;
(3) Identify possible ways that forming operations can go wrong;
(4) Summarize construction pitfalls and how to avoid them.

10:00 AM - 12:00 PM

Moderator: Daniel A Kuchma

To introduce the ACI community to concepts and opportunities to provide support structures (towers and foundations) for wind turbines. This would include tall towers for onshore wind, as well as gravity-based and floating concrete foundations for offshore wind turbines. The use of concrete support structures provides many advantages over steel solutions. For onshore wind support structures, these includes addressing transportation and erection challenges and lower costs. In addition to these, for offshore wind turbines the advantages include much longer design lives, local fabrication capacity, and overcoming the impact on sensitive marine habitats such as the North Atlantic Right Whale.
Learning Objectives:
(1) Introduce the design and analysis process for concrete support structures for wind turbines;
(2) Discuss the role of dynamic response and turbine control settings on structural demands;
(3) Discuss innovative design solutions, technical changes, the project process;
(4) Name the characteristics of the market opportunity.

1:00 PM - 3:00 PM

Moderators: Ahmed Al-Rahmani, Robert Thomas

The ACI 123 Student Poster Session complements the existing Research in Progress and Open Topic sessions and provides further opportunity for the presentation of original, unpublished results from ongoing research projects and leading-edge concrete technology throughout the world.
Learning Objectives:
(1) Recognize ongoing structural research projects from a wide range of research topics;
(2) Discuss recent techniques, research methods, and procedures related to structural aspects of concrete research;
(3) Describe emerging ideas in structural concrete research;
(4) Summarize recent technical information related to structural concrete research.

1:00 PM - 3:00 PM

Moderator: G Terry Harris

This session will aid the ready mix producer, designer, specifier, and contractor on projects that either have projects or are considering the use of self-consolidating concrete (SCC) on a project. Attendees will learn practical information on the proportioning, production, placing, and quality control of SCC.
Learning Objectives:
(1) Discuss how to develop a quality control plan;
(2) Explain practical placing guidelines for SCC;
(3) Review the production of SCC;
(4) Summarize how to specify an SCC mix.
