A set of experiments were carried out with the objective to determine the behavior of concrete columns under seismic loads. A Load-Boundary Condition Box (LBCB) mounted to the reaction wall was used to apply both bending moment and normal force to the column. This set of experiments were sponsored by the Network of Earthquake Engineering […]
This testing program was sponsored by the Illinois Department of Transportation (IDOT) in June 2008. There was an issue of ultimate strength of the lifting loops, which are built in to the concrete girders used on bridges and overpasses. The loops are made up of 7-wire strands, with a diameter of 0.5 in. Prof. D. […]
A series of tests were conducted on High-Performance Fiber Reinforced Cementitious composites using the Bi-Axial 100 kip testing frame. This project was sponsored by NEES under supervision from Prof. James LaFave; graduate student Raymond Foltz was the leading person in instrumentation, testing procedure, and data analysis. Specimens were subjected to bi-axial state of stress, and […]
A series of cyclic tests on Buckling-Resistant Braces were conducted in the NSEL in September 2007. using the 600-kip testing frame. This project was sponsored by Nippon Steel under supervision from Prof. Jerry Hajjar from University of Illinois at Urbana-Champaign, and Prof. Toru Takeuchi from Tokyo University. Graduate student Ryota Matsui was the leading person […]
Principal Investigator: Prof. J. LaFave Research Assistant: Dziugas RENECKIS The effect of seismic activity on existing structures is inconclusive despite ongoing research. Brick veneer wall damage has been observed in recent years resulting from strong winds and moderate earthquakes. A study has been undertaken to evaluate the performance of brick masonry veneer wall systems over […]
A series of tests of concrete columns retrofitted with Shape Memory Alloy (SMA) and Glass Fibers (GF) were tested in NSEL using a custom-built testing setup. This project was sponsored by Illinois Department of Transportation (IDOT) under supervision of Prof. Bassem ANDRAWES from the University of Illinois at Urbana-Champaign. Graduate students Nicholas Wierschem and Moochul […]
3-Point Bending Test of Bridge Beam The objective of this test was to determine the strength of concrete beam removed from a bridge built 60 years ago. This project is a part of Illinois Program to rebuild the state infrastructure. Click here to see the presentation of Tom GOLECKI , the student in charge of […]
The objective of this testing was to determine the performance of scaled (reduced size) bumper used at docks of seaports. Testing of full size bumper was performed using 3 million lbf capacity testing frame located in Talbot Laboratory at the UIUC.
The objective of this project was to design and build a cost-effective frame structure that can resist earthquake excitations. Karl EID was the leader of a team that built the tower. The following students participated in the project: Chang CHEN, Zhichao SUN, Woongchan BANG, Sammy PARK, Krishna PATEL, Mengxio ZHONG, Shannon CHEN, Keats HUA, and Wendy WENDY.
