PI: Prof. Jeff Baur and Dr. Logesh Shanmugam Students from the Aerospace Engineering department visited NSEL to test their composite bridge specimens for a chance to enter the International SAMPE Competition during the annual conference.
PI: Prof. Jeffery R. Roesler and Dr. Jordan Ouellet Graduate Students: Lama Abufares, Alexander Sandoval, Fahad Ali, and Ben Manaugh The new volumetrics-based RCC mix design (Ouellet, 2025) was further investigated by ICT graduate students using fractionated reclaimed asphalt pavement (FRAP) as coarse aggregate replacement at 0%, 50%, and 100% by weight. Fresh-state characterization included […]
Our facility recently acquired an MTS 55-kip axial/torsional load frame model 309.30, from AMTEL of the Aerospace Engineering Department. The load frame can apply axial loads up to 55 kips and also 2,000 ft-lb of torque simultaneously. The total axial actuator stroke is 6″ and the rotary actuator rotation is limited to 100 degrees.
Our 5.5-kip hydraulic load frame was upgraded for better portability. Both the load frame and station were mounted on mobile carts, allowing us to operate them anywhere in the facility. The polycarbonate enclosure makes this load frame ideal for safe demonstrations. This load frame has hydraulic grips allowing us to test specimens dynamically in compression […]
PI: Prof. Jeffery R. Rosler and Prof. Oscar Lopez-Pamies Digital image correlation was performed while loading roller-compacted concrete (RCC) discs in indirect tension (split tensile). Load frame compliance was measured for various load levels by subtracting the DIC displacements from the total actuator displacements. Colored strain mapping was superposed over the specimen surface, to evaluate […]
We are pleased to announce that Wyatt Riemma and Dilan Yusgiantoro have joined the Newmark Structural Engineering Laboratory (NSEL) as Undergraduate Laboratory Technicians. In their new roles, Wyatt and Dilan will support ongoing experimental research, assist with laboratory operations, and contribute to maintaining a safe and effective testing environment. Please join us in welcoming Wyatt […]
A 2 kN (450 lbf) mechanical proving ring was recently calibrated for Prof. Tim Stark, in the preparation of the laboratory section of CEE 483 – Soil Mechanics and Behavior.
“The results confirmed the finite element modeling – the stress deep in the embedded components is sufficiently low that fatigue is not a concern and USACE can likely reduce the scope of their anchorage replacement efforts, potentially saving millions of dollars.”
PIs: Marcus Dersch, P.E. | Arthur Lima Experiments were conducted in a loading frame filled with ~24 inches of ballast material. A track panel (half-crossties and rail) were placed on top of the ballast and vertical loads were applied to the rail at the center crosstie using a manual hydraulic jack reacting off of the […]

PI: M. Golparvar-Fard/ Student: A. Ibrahim This research explores new path planning and navigation methods for autonomous robotic platforms that support reality capture on construction sites. New methods and metrics are developed that guarantee accuracy and completeness of reality mapping for construction progress and quality monitoring applications. Lab testing is used to validate the performance […]
PI: B. Andrawes/Student: K.E. Kim Bridges with various timber structural components make up a large portion of the transportation infrastructure in the US. Bridges supported on timber pile substructure, simply referred to as timber pile bridges, are particularly common. Many timber pile bridges still in service today were constructed in the 1950’s and 60’s using […]
PI: B. Andrawes/Student: A. Zafar For many years, steel has been used as the primary reinforcing material for concrete structures. Despite requisite stiffness, strength, ductility and desired deflection properties, steel reinforcing bars have tendency to incur permanent plastic deformations under excessive loading. Recently, fiber reinforced polymer (FRP) reinforcing bars have also been used in concrete […]
PI: B. Andrawes/Student: M. Sung This project focused on developing an Adaptive Prestressing System (APS) for concrete crossties. The new prestressing system utilizes a unique characteristic of a class of smart materials known as Shape Memory Alloys (SMAs). Through heating, a SMA can recover its original shape after being excessively deformed beyond its elastic range. […]
PI: B. Andrawes/Student: A. Pozolo Self-consolidating concrete (SCC) is a workable yet stable concrete which flows easily and consolidates under its own weight. Its unique properties can substantially reduce the labor required to pour complex or heavily reinforced structural members. Over the past decade, the American precast industry has taken significant strides to adopt SCC […]
PI: B. Andrawes/Student: H. Zhao Concrete bridges play an important role in the transportation network. However, there are more than 56,000 bridges that have been identified as structurally deficient in the U.S., especially those bridges located in the Northern part of the U.S. where harsh climate inflicts severe damage to the structural integrity and durability […]
PI: B. Andrawes/Students: M. Shin and Q. Chen This research focuses on examining the use of shape memory alloy (SMA) spirals in the seismic retrofitting and repair of reinforced concrete (RC) bridge columns. The thermally triggered recovery stress of pre-strained SMA spirals is utilized to apply large active confinement pressure at the column’s plastic hinge […]
PI: J. Roesler / Student: A. Bordelon A series of bending tests were performed on concrete beams in 2007 by grad student Amanda Bordelon under the supervision of Prof. Jeffrey Roesler. Beams were tested in 3-point and 4-point bending configurations. Well defined post-peak behavior was achieved.
