CE 112: Water & Wastewater Systems Design and Operation

As a new activity by the Center for Smart Infrastructure (CSI), Professor Kenichi Soga, Won-jun Cha, Shih-Hung Chiu, and East Bay Municipal Utility District (EBMUD) subject-matter experts, led by Clifford Chan (General Manager) and David Katzev, opened a new undergraduate course for Fall 2022: Water & Wastewater Systems Design and Operation (CE112). The course covers a variety of topics in the water industry, including design… Read More »CE 112: Water & Wastewater Systems Design and Operation

Shell’s visit to the Center for Smart Infrastructure

On Wednesday, October 12th, delegates from Shell (Marwa Al-Ansary, Leonardo Spanu, and Andreas Matzakos) visited the Center for Smart Infrastructure. It was great to see Marwa, who was with Professor Soga during her PhD at Cambridge. Our visitors saw our large-scale testing facilities and interacted with drones, artificial reality and virtual reality devices, distributed fiber optic sensors, smart pavement and mobile robots, and other technologies… Read More »Shell’s visit to the Center for Smart Infrastructure

CSI group conducted two biaxial tension tests for the ductile iron pipe

Two biaxial tension tests were conducted on August 31st and September 28th by the Center of Smart Infrastructure (CSI) group at Davis Hall. The TR-XTREME ductile iron pipes manufactured by U.S. Pipe, designed to maintain the full-service life after seismic events, were tested. The experiment aims to test the capability of the joint of the pipe under different locking segment configurations while subjected to vertical… Read More »CSI group conducted two biaxial tension tests for the ductile iron pipe

Model Bridge Tests for CE 170A (Infrastructure Sensing and Modeling)

Students of CE 170A (Infrastructure Sensing and Modeling, taught by Professor Soga, Professor Kayen, and Professor Zekkos) had a lot of fun on September 14th. Model bridge tests were conducted as part of the Infrastructure Sensing module of the course, led by Jaewon and Shih-Hung. Three different bridges (single-angle, double-angle, double-angle with defect) were instrumented with distributed fiber optic sensors (put on by our students!), linear… Read More »Model Bridge Tests for CE 170A (Infrastructure Sensing and Modeling)

Thermal Conductivity Tests in 400-ft-deep Borehole on Campus

On September 2nd and Sepember 21st, two Thermal Conductivity Tests were conducted through the U-bend looping pipe grouted in a 400-feet-deep borehole near the University House on campus. Fiber optic sensors were installed both inside and outside the looping pipe to monitor the temperature distribution along the depth and temperature variation with time. In the two tests, BOTDA and BOTDR analyzers provided two different methods… Read More »Thermal Conductivity Tests in 400-ft-deep Borehole on Campus

Congressman Swalwell’s visit to the CSI

On Tuesday, April 19, Congressman Eric Swalwell of California’s 15th Congressional District visited the Center for Smart Infrastructure. Researchers of the Soga Research Group, colleagues from the Civil and Environmental Engineering department, campus administrators, and industry partners presented various technologies and projects to envision collaborative opportunities for monitoring the health of our civil infrastructure.
