Seismic Performance of Railway Bridges
Historically, the seismic performance of railway bridges in the U.S.A. has been very satisfactory during earthquakes of this century. There are many possible factors contributing to this...
Instrumentation and Testing of a Three Hinge Arch for Service Loads Increase
A three hinge arch railroad bridge was instrumented and tested to evaluate its condition and the required modification for increasing the service loads. Initially the structure was designed...
Field Tests of Railway Bridges
A research program focused on the evaluation of railway bridges has been underway for the past five years. The objectives of a research are as follows: (1) determine the loading spectra...
Interpretation of Nondestructive Integrity Tests Using Artificial Neural Networks
A barrier to more frequent use of nondestructive integrity tests on cast-in-place foundations is the difficulty of interpreting the test results to identify the presence or absence of...
