Book Description
Loads were applied to the structure in the undamaged condition to obtain baseline behavior and at various levels of damage. Damage was inflicted to the exterior girder of the bridge to simulate field damage. Damage consisted of both removal of concrete and the severing of the prestressing strands. Concrete and steel were removed in small increments so that critical levels of damage could be determined. A total of thirteen levels of damage were inflicted on the exterior girder, each subjected to various load tests. The results of the tests are compared throughout the range of damage levels to determine bridge behavior in the damaged condition.

Book Description
Experimental data from static and dynamic tests on 1/7-scale direct models of simply supported, one- and two-cell, box girder bridges are presented. Variation of flexural and torsional stiffnesses and dynamic characteristics, such as the natural frequency of vibrations and dampinig ratios of the bridge models at different levels of cracking damage, are examined; in turn, these dynamic characteristics can be used to estimate the cracking damage in the bridge. the physical model proved to be an adequate tool for the study of static and dynamic responses of box girder bridges at all load levels.

Book Description
An experimental study of the behaviour of a 1:7.10 scale direct physical model of a simply supported single span, one cell, prestressed concrete box girder bridge is presented. The experimental techniques developed for construction and the instrumentation required during testing of the bridge model are summarized. Variation of the flexural stiffness and the dynamic characteristics, such as the damping ratio and the fundamental natural frequency, of the bridge model at different level of damage are presented.
