Near-Optimal Sensor Placement for Health Monitoring of Civil Structures

In this paper we focus on the optimal placement of sensors for state estimation-based continuous health monitoring of structures using three approaches.  The first aims to minimize the static estimation error of the structure deflections, using the linear stiffness...

Contact Interface in Seismic Analysis of Circular Tunnels

The seismic analysis of underground structures requires a careful consideration of the important effect of shear strains in the soil due to vertically propagating horizontal shear waves. These strains result in ovaling deformations of circular tunnels or racking...

Seismic Vulnerability Study of the Auburn-Foresthill Bridge

The Auburn-Foresthill Bridge is a 2,428 ft steel suspension bridge that links the towns of Auburn and Foresthill, California and was built in1973. While it is ranked 3rd in the U.S., it is the tallest bridge in California. The bridge is located in the seismically...

Seismic Response of Precast Tunnel Linings

Precast concrete segmental lining systems have been gaining widespread use in seismically active areas and a single-pass version of such a system has been developed for use on the Silicon Valley Rapid Transit (SVRT) Project in San Jose, California. The response of...
