The objective of this session is to explore the latest advancements in emerging technologies that are enhancing the accuracy, reliability, and efficiency of finite element analysis (FEA) in the simulation and design of structural concrete. The focus will be on improving simulation techniques, material models, and computational tools, thereby enhancing the confidence of engineers and researchers in using FEA for concrete structures. The session aims to bridge the gap between cutting-edge technology and practical application in structural concrete, providing solutions to common challenges faced in the modeling and analysis of complex concrete systems.
Moderators: Dr Mervyn J Kowalsky, Dr Jeffrey Rautenberg
Estimates of the deformation capacity of RC structures have been developed since the late 90’s. There are numerous methods proposed within seismic design and assessment guidelines to estimate deformation capacity, which can lead to variations in the assumed capacity of the structure. The objective of this session is to compare the effectiveness of existing methods to estimate deformation capacity of RC structures as well as propose alternative, novel methods. The implications of these results will be discussed.

Ultra-high performance concrete (UHPC) is a novel class of concrete that has superior mechanical properties and durability characteristics. Although UHPC exhibits exceptional performance at room temperature, the behavior of UHPC under fire conditions can be of concern due to faster degradation of strength and modulus properties with temperature, as well as its high susceptibility to fire-induced spalling. Since UHPC is a new construction material, there is limited information on its fire performance. This session will invite research and industry groups to share information on the fire performance of UHPC with students, faculty, researchers, and practitioners. Attendees will learn about the current fire problems in UHPC, recognize knowledge gaps and research needs, and practical solutions for improving UHPC fire performance.

The objective of this session is to present state-of-the-art information that links the state of the practice with low GWP mixtures. The pros and cons of low GWP mixtures will be discussed as they relate to service life. It is anticipated that this session will highlight beneficial outcomes associated with high clinker replacements with reactive supplementary cement. The talks will also highlight concerns related to low CH, corrosion resistance, and freeze-thaw resistance. The audience would be researchers, material suppliers, and design professionals.

Structural engineers face growing pressure to minimize slab thickness for cost and carbon reduction while ensuring adequate deflection performance. Limited resources and minimal guidance from building codes on long-term deflection methods add to the challenge. This session, designed for practicing engineers but valuable to academics and contractors as well, provides insights from experienced professionals on best practices in long-term slab deflection analysis. Attendees will gain practical knowledge to enhance their design decisions.
