Seismic Vulnerability of the Highway System

Task F2-2: Hardware Acquisition for the Cape Girardeau Cable-Stayed Bridge
Subject Area: Special Studies

Principal Investigator(s) and Institution(s)
Ian M. Friedland, MCEER

Objective and Approach
Under Task F2-1, a detailed design plan is being developed for seismic instrumentation of the Cape Girardeau cable-stayed bridge, which is currently under construction across the Mississippi River between Missouri and Illinois. Task F2-1 will provide a detailed and itemized list of hardware, and result in a solicitation from vendors with price quotes. Under this task, the hardware for seismic instrumentation will be acquired on the basis of the vendor quotes and turned over to the Missouri Department of Transportation (MoDOT) for installation.

The U.S. Geological Survey (USGS) will prepare the instrumentation design, and an independent consultant will check it, under Task F2-1. In addition the USGS, as part of its earthquake hazard reduction program, has agreed to establish a mechanism and appropriate agreements with MoDOT and the FHWA to maintain the instruments, retrieve, process, and disseminate strong-motion response data following events in the future.
