Teaching Machines to Classify and Organize Reconnaissance Image Data
The methods developed and validated in this research will enable rapid information extraction from these images to make timely decisions regarding where to collect the highest value perishable visual data.
Resilient ExtraTerrestrial Habitat Engineering (RETH) Resilient ExtraTerrestrial Habitat Engineering (RETH)
The goal of this project is to develop the expertise needed to address the grand challenge of permanent human settlements outside Earth.
Establishing a Research Network in Hybrid Simulation for Multi-Hazard Engineering
This NSF-funded research coordination network seeks to broaden the community and forge new partnerships able to tackle the scientific challenges that lie ahead, and thus facilitate the advances needed to both establish the fundamental theory of and expand the capacity for hybrid simulation methods for natural hazards applications.
Probability of Detection Study for Bridge Inspection Related to Steel Bridges
To evaluate the current performance of inspectors with the industry's present standards of training, a comprehensive Probability of Detection (POD) study is underway to determine the likelihood of inspectors finding cracks of various sizes and surface corrosion on a bridge structure. This study will test an inspector's �� ability to identify different defects under various environmental conditions on a bridge structure.
Seismic Response of Structural Walls with Reinforcement and Geometric Discontinuities Seismic Response of Structural Walls with Reinforcement and Geometric Discontinuities
The objective of this project was to study the seismic response of structural walls with a vertical stack of openings that terminate in a solid wall in the lower stories in building structures.
Member-level Redundancy in Built-up Steel Members Member-level Redundancy in Built-up Steel Members
The objective of this research is to quantify the redundancy possessed by built-up steel members (bolted or riveted). Typically, built-up members will not 'fail' if one of the components fails (whether through fatigue or fracture). However, there is very little experimental data quantifying the remaining fatigue life and strength of a member in which one of the components has failed.
Seismic Response of Reinforced Concrete Walls with Lap Splices Seismic Response of Reinforced Concrete Walls with Lap Splices
Lap-splice failures in reinforced concrete walls and smoke stacks after recent earthquakes (e.g. Izmit, Turkey in 1999, Northridge, United States in 1994, Maule, Chile in 2010) and the scarcity of experimental data revealed the need for this investigation.
Modal Analysis and Load Identification Techniques for a Rapidly Emplaced Bridge System Modal Analysis and Load Identification Techniques for a Rapidly Emplaced Bridge System
This project's goals are first to determine through experimental procedures the vibration behavior of a military-type deployable bridge under various types of loading conditions, e. g.: moving mass, moving load and moving oscillator travelling along the bridge at different speeds; and second, to develop a valid approach to identify the type of load the bridge is subjected to from experimental data only.
Laboratory Testing of Railroad Flatcars For Use as Highway Bridges on Low-Volume Roads to Determine Ultimate Strength and Redundancy Laboratory Testing of Railroad Flatcars For Use as Highway Bridges on Low-Volume Roads to Determine Ultimate Strength and Redundancy
Several counties in Indiana use retired railroad flatcars for a bridge superstructure to replace existing deteriorating county bridges. There are over 130 railroad flatcar bridges in the state of Indiana. The main objective of this laboratory project is to provide greater confidence to county engineers when load rating these bridges by studying the ultimate strength and load redundancy of the bridge system. Testing in the laboratory creates the opportunities to test at larger loads, use a greater number of instrumentation, and simulate a controlled fracture test.
US-China: Verification of Real-Time Hybrid Simulation Through Shake Table Comparison US-China: Verification of Real-Time Hybrid Simulation Through Shake Table Comparison
Real-time hybrid simulation (RTHS) provides researchers the opportunity to isolate and physically investigate only the more complex or critical components, while numerically including the remainder of the structure. This approach allows for a wide range of configurations to be tested using a single test specimen. This work present the results of a three phase project focusing on comparison of analytical simulation, physical full-scale tests and real-time hybrid simulation tests of a medium-scale prototype structure under various earthquake inputs.
