Dr. Sanayei is a leading researcher in the field of bridge structural health monitoring (SHM). He has worked on the implementation of bridge condition assessment using static and dynamic nondestructive test data in the presence of measurement and modeling errors. He has also developed bridge signatures, an innovative nonparametric probabilistic method using operational bridge responses due to daily traffic, for structural condition assessment. He has conducted a number of full-scale bridge static and dynamic nondestructive tests, modeling, and evaluations for Tobin Bridge in Boston, Powder Mill Bridge in MA, and the Memorial Bridge in NH.
Dr. Sanayei is also an expert in building floor vibrations and structure-borne noise for human comfort, operation of sensitive equipment, and precision manufacturing. In recent years, the exploitation of air-rights construction has resulted in buildings being subjected to potentially disturbing vibrations and noise from urban rail lines and roadways. He has conducted a number of full-scale building floor vibration tests for impedance modeling and vibration predictions, including the Boston Convention Center, Hynes Convention Center, TD Garden, and the MIT Brain and Cognitive Science Center, and over-train-track buildings atop a metro depot in China.
Dr. Sanayei's research also include implementation of structural condition assessment using operational nondestructive dynamic test data for multi-axial non-proportional fatigue life prediction. His has used wireless instrumentation, nondestructive testing, data acquisition, use of combined accelerations and strain measurements. He has performed full-scale tests on structures such as roller coasters and bridges with unique and complex connection details.
