Stateside Podcast: Is the Mackinac Bridge vulnerable to a freighter strike?

Dr. Venkatesh Kodur, a professor of civil and environmental engineering at Michigan State University, spoke to how these protections are added to existing bridges.
“[Bumpers] can be implemented in the current bridges we have, but it requires a little bit of effort,” Kodur said. “For the existing bridges, it can be done, but it requires some planning, a little bit more cost than what it would have been when it was originally built.”

Mackinac Bridge safety is drawing more public interest than usual after the tragic collapse of the Francis Scott Key Bridge on March 26. Michigan State University engineer, Dr. Venkatesh Kodur said the collapse was rare for Baltimore, and it would be just as rare for a Michigan bridge. Dr. Venkatesh Kodur, MSU Engineer: “So typically, they are all well designed for, most of the time, but the events which happened in Baltimore, they are called extreme events, they don’t happen all the time.”

A steel bridge exposed to the heat of a fire can fail in 20 minutes, says Venkatesh Kodur, a Michigan State University civil and environmental engineering professor, who would like all fire-susceptible bridges in the world to be made fireproof. Kodur is the founding director of the university’s Center on Structural Fire Engineering and Diagnostics; it’s the first testing facility of its kind in the country, where researchers model all kinds of structures, including buildings, airports, tunnels, and steel bridge girders, for fire-resistant design.

Performance of steel beams with endplate connections exposed to fire
Advances in Structural Engineering2024
This paper presents results from an experimental study on the fire behavior of endplate joints and the connected steel beams in a moment resisting frame (MRF). Utilizing the subframe assemblage, full-scale steel beams with various endplate connections were tested according to the ISO834 standard fire exposure. The thermal and structural responses of the beam and its endplate joints to the column, together with failure modes were monitored throughout the fire test. The effect of key factors such as endplate dimensions, bolt size and grade, and the presence of stiffeners were investigated. The results of the fire tests show that the specimen experiences flexural failure in 746–773°C temperature range, through mid-span deflection exceeding the deflection limit as per British standard 476.
Fire hazard in concrete bridges: review, assessment and mitigation strategies
Structure and Infrastructure Engineering2024
This paper analyses the vulnerability of concrete bridges to fire through a comprehensive review and proposes strategies to overcome the fire hazard. As part of mitigation strategies, the application of advanced analysis is illustrated through developing a non-linear transient finite-element model for fire resistance evaluation of prestressed concrete bridge girders. The numerical model is validated using results from fire tests on concrete beams. The model is applied to investigate the effect of girder shape (rectangular and I-shaped sections) and strength of concrete (normal- and high-strength concretes) on the fire resistance of typical concrete bridge girders. Results from the analysis clearly show that fire resistance of high-strength concrete (HSC) girders is lower than that of normal-strength concrete (NSC) girders, which is attributed to its faster degradation of strength and stiffness with temperature.
A comparative study between ultra-high-performance concrete structures and normal strength concrete structures exposed to fire
Structures2024
The use of ultra-high-performance concrete (UHPC) in civil infrastructure is increasing due to its numerous advantages compared to normal strength concrete (NSC). In this research, thermal analysis of NSC and UHPC beams and columns was developed to understand and compare the fire performance of these structures. A numerical analysis was performed using finite element (FE) modeling with ABAQUS software. Compared to NSC, UHPC structures in some cases have lower fire resistance due to their slender cross-sections and unfavorable thermal properties and mechanical capacity degradation due to temperature effect. The results show that UHPC structures experience significantly higher cross-sectional temperatures when exposed to fire compared to NSC.
Comparative fire behavior of reinforced concrete beams made of different concrete strengths
Fire Technology2024
This paper presents the comparative fire performance of reinforced concrete (RC) beams made of concretes with different strengths by undertaking fire resistance tests. Four RC beams made of normal strength concrete (NSC), high strength concrete (HSC), and ultra-high performance concrete (UHPC) with different fiber combinations, were subjected to structural loading and tested under fire conditions. Results from the fire resistance tests show that UHPC beams undergo severe fire-induced spalling and exhibit lower fire resistance as compared to HSC and NSC beams. Additionally, the inclusion of polypropylene (PP) fibers in UHPC beams aids in reducing spalling and increasing fire resistance in UHPC beams.
Evaluating Shear Response of UHPC Bridge Girders Exposed to Fire
Fire Technology2024
The use of advanced materials, such as ultra-high-performance concrete (UHPC), and slender cross-sectional shapes in bridge girders can result in high susceptibility to shear failure during fire exposure. Shear limit state is usually not considered in fire design, which can be a major risk for I-shaped girders with slender webs. This paper presents the development of an approach to evaluate the shear capacity of UHPC bridge girders during fire through extension of room temperature capacity equations to elevated temperatures. Four types of standard AASHTO concrete bridge girders are analyzed under both standard and hydrocarbon fire scenarios. The output results are utilized to evaluate the progression of temperatures and deflections throughout fire exposure, as well as estimate degradation in flexural and shear capacities.
