"Resilience of Post-Tensioned Box Girders"

NCBC is pleased to continue its webinar program on Wednesday, May 22, 2025, from 1:00 to 2:00 pm ET.

This webinar will review case studies exemplifying the resilience of grouted post-tensioned box girders. Lessons learned from the evaluation of in-service bridges in corrosive environments, historical construction practices, and damage from fire incidents will be shared. Information captured from planned demolition will also be presented.

Following this webinar, the participants will be able to:

• Understand the service life impact of historical construction practices of post-tensioned box girders
• Evaluate the impact of grout voids on the performance of PT tendons
• Recognize the inherent toughness of grouted PT bridges
• Identify when grout concerns may exist
• Understand the range of specialized assessment techniques that can be used for PT assessments

"Mastering Bridge Geometry: Insights into Precast Concrete Segmental"

NCBC is pleased to continue its webinar program on Wednesday, April 23 , 2025, from 1:00 to 2:00 pm ET.

Since their introduction more than 50 years ago concrete segmental bridges have played an important part in our infrastructure. Specialized casting and construction methods have produced cost-effective bridges that are adaptable to any highway geometry or site constraints. This online seminar covers segmental geometry, span lengths, construction methods, casting methods, ASBI resources. Following this webinar, the participants will be able to:

• Describe the geometric definitions required to define and control segmental bridge geometry.
• Understand the impact of segmental construction method on segment geometric layout.
• Describe the features of precast segment casting yard geometry control.
• Understand the interaction between as-cast geometry and subsequent casting corrections.

"Truck platoons and understanding the impact of heavy loads on prestressed concrete girders"

NCBC is pleased to continue its webinar program on Wednesday, March 19, 2025, from 1:00 to 2:00 pm ET.

This webinar reflects on the history of the stress limitation approach and how that may impose unnecessary limitations on platooning operations. Reliability indices associated with different load levels will be discussed. The research performed on platooning will help guide structural design in the future. Following this webinar, the participant will be able to:

• Categorize the fundamental variabilities associated with loads and resistances
• Relate variabilities to load factor calibration
• Describe a possible platoon permit rating for strength and service
• Review cracking likelihood for the 75-year service life
• Consider how alternate methods or criteria might be used in load rating

"The Critical Role of Construction Engineers in Building Bridges "

NCBC is pleased to continue its webinar program on Wednesday, October 16, 2024, from 1:00 to 2:00 pm ET.

Many of today’s bridge projects require unconventional construction schemes to hurdle site constraints and meet project requirements. Often, these projects require an analysis of the structure during the construction phase since the construction loads may control the design or the means and methods affect the locked-in forces and geometry. This webinar will investigate the role of a Construction Engineer, and how their involvement can bridge the gap between the Designer and Contractor on complex projects.
