A well-designed themed concrete building is one that achieves the minimum performance levels, and the team members and guests are all satisfied with the results. This typically occurs when the creative intent is maintained throughout the design and construction process while ensuring cost and schedule goals are achieved. Beato will explore a compilation of real-world experiences from a structural design and construction perspective of major theme park developments internationally, focused on identifying the best practices to approach these massive projects so design and construction time is used efficiently. Get informed on ways to design and structure themed concrete buildings so the most cost-effective structure is achieved while delivering best-in-class entertainment.

Plain concrete design is used routinely as a means and method for Tilt-up Construction. Wall panels are designed to remain in the uncracked state during erection based on flexural tensile strength as measured by ASTM C78. The methods used by the tilt-up industry and the ASTM testing method employed to assure successful panel erection and long-term performance are examined.
Learning Objectives:
(1) Develop an understanding of how plain concrete design methods used in the Tilt-up Industry;
(2) Describe the ASTM C78 Testing Method;
(3) Recognize the impact of factors that affect initial and long-term performance;
(4) Identify the limitations of plain structural concrete.


1:30 PM - 3:30 PM

Moderators: James R Baty, Andrew S McPherson

This session is designed to begin expressing the advancements in the industry for engineering tilt-up panels for projects requiring seismic performance; insulation; and excessive threshold loading. Sessions will offer the latest in risks for misinterpreting the application of the slenderness wall method and how panels behave under various loading conditions.
Learning Objectives:
(1) Learn of the proper application of engineering principles to tilt-up wall panel design;
(2) Understand the history of practical experience verified by testing for confidence in predictive behavior;
(3) Identify the opportunities to retrofit existing tilt-up buildings and the repercussions on design;
(4) Learn of the advancing technology for thinner insulated walls for sustainability.


1:30 PM - 3:30 PM

Moderators: Brian Carson, Peter J Ruttura

Today’s designer and contractor have to be more sophisticated understanding how tolerances can affect constructability and concrete quality control. Productivity is affected with the constructability of concrete systems. Proper measurement, analysis and application of tolerances can enhance the constructability and concrete productivity. An overly conservative design approach generates an expensive solution.
Learning Objectives:
(1) Explain design considerations coordinated with tolerances affecting construction of multi-story concrete structures;
(2) Recognize that non-destructive testing methods and analysis of the data require an understanding of the limitations of the technology, particularly that significant digits affect the data analysis respective to tolerances;
(3) Discuss potential amendments to ACI 117 tolerances for slab-on-grade based on new research data;
(4) Discuss compliance with paving thickness tolerances in ACI 117.


1:30 PM - 3:30 PM

Moderators: Samhar S Hoz, Jorge L Quiros

1:30 PM - 3:30 PM

Moderator: Farshad Rajabipour

As the supply of conventional supplementary cementitious materials (SCMs) continue to fall behind concrete industry’s demand, new sources must be identified and evaluated to allow production of high-quality and durable concrete. This session reports on the latest research related to the use of ground bottom ash as a concrete SCM. These include studies on the chemical and physical characteristics of ground bottom ash, its pozzolanic reactivity, and its performance in concrete in terms of its impact on fresh, mechanical, and durability properties of concrete mixtures. The audience will become familiar with this potentially valuable new SCM source.
Learning Objectives:
(1) Compare the properties and performance of ground bottom ash versus fly ash and other concrete SCMs;
(2) Recognize the impact of bottom ash pozzolan on fresh and hardened properties of concrete;
(3) Explain the use of coal bottom ash to enhance concrete durability;
(4) Identify methods for assessing the reactivity of bottom ash and other SCMs.


4:00 PM - 6:00 PM

Moderators: Dimitri Feys, Mohammed Sonebi

This session is co-sponsored by RILEM TC266: Measuring Rheological Properties of Concrete in May 2018 (Béthune, France), a subgroup of “RILEM TC266: Measuring rheological properties of concrete” has conducted the third International Round-Robin Test (RRT) on comparing nine concrete rheometers. The RRT was primary focused on workability, flow curves, thixotropy and interface rheology. The goal of the proposed session is to inform academics, contractors, concrete producers, and materials suppliers on the outcomes of this testing campaign.
Learning Objectives
(1) Identify the equipment used in the round-robin test on concrete rheometers;
(2) Discuss the reasoning behind the selection of the procedures;
(3) Compare the results from different rheometers;
(4) Explain the causes for differences between the devices.

No international organization is sponsoring, but speakers from Germany, China, Italy, and India are part of the speaker list, and have agreed to present. 3D printing technology is growing at an unprecedented speed. A variety of objects, including houses, bridges, and structural and architectural components, have been printed with various cement-based materials. However, studies on the properties of hardened 3D-printed concrete are still limited. In the commonly used extrusion-based 3D printing process, the layer-by-layer deposition procedure has made the properties of 3D-printed concrete intrinsically different from those of traditional mold-cast concrete. For instance, 3D-printed concrete components may have cellular structures resulting from element configurations and infills, defects caused by filament discontinuity and non-uniformity, and anisotropic behavior depending upon printing and/or loading directions. Thus, special considerations for evaluation and characterization of the properties and performance of hardened 3D-printed cement-based materials are necessary. Recently, some progress has been made to address the related issues through examinations and evaluations of mechanical properties (e.g., compressive, tensile, and interlayer bond strengths), microstructures (bulk filaments and interlayers), and early age volume stability of 3D-printed cement-based materials. This session has participants from the international networks of networks (AccelNet) consortium 3DConcrete.
Learning Objectives:
(1) Identify key issues in testing and characterization of the properties and performance of hardened 3D-printed cement-based materials;
(2) Recognize the emerging methodology for and results from testing and characterization of 3 hardened D-printed cement-based materials;
(3) Explain the effects of materials on properties of 3D printed concrete;
(4) Describe the advances in material that are being used in concrete 3D printing.


4:00 PM - 6:00 PM

Moderators: Nakin Suksawang, Mahmoud Maamouri

The evaluation of new and existing concrete structures relies on structural reliability and safety approaches to understand their existing capacity, safety, and future expected life. ASCE 7-16 provides basic guidelines to help engineers to obtain this information with a well-defined target reliability index for new structures. However, the process for existing structures evaluation is undefined. The objective of the proposed session is to present the challenges and remedies engineers have in evaluating concrete structures that can be easily understood by the practitioner. Presentation on evaluation methods, prediction models, reliability analysis, reliability index and code calibration will be presented. Engineers and Researchers should attend.
Learning Objectives:
(1) Recognize the impact of structural reliability and its application on structural condition assessment;
(2) Identify potential evaluation methods and strategies for rehabilitate concrete structures;
(3) Describe the importance of other limit states that may impact the service life of the structures;
(4) Explain structural reliability basics and their application on quantifying structural performance.
