Book Description
The use of concrete cores and nondestructive testing for strength evaluation of existing structures is illustrated through an evaluation of an existing concrete bridge. the results confirm that rebound hammer number should not be used alone as an indicator of in situ compressive strength. reasonably good correlation is demonstrated between pulse velocity and compressive strength, with a slight improvement when pulse velocity and rebound number are combined. a probabilistic approach to structural evaluation of existing structures is proposed in whih the variability of in situ concrete compression strength and uncertainty associated with indirect nondestructive testing are incorporated. an example of shear strength is given, which indicates a range of increase in shear strength compared with initial design parameters of 17-37% depending on the amount and type of data available.

Book Description
Compressive strength tests on concrete cores taken from existing bridge structuers are often used as a tool in evaluating the strength of the existing structure. Some difficulties are, however, encountered in interpreting the result of these tests and incorporating appropriate values in the usual equations for determining strength of structural members. In this paper, relationships between core tests, cylinder tests, and in situ strength ar reviewed based on data reported in the literature. Methods for incorporating core test data into a limit states design approach for strength evalulation are investigated. A method is proposed to convert data from compressive strength tests on cores into an equivalent design compressive strength that can be used in the normal design equations for strength. The method is applied to the analysis of an existing bridge for which core test data are available.

Book Description
Contains three keynote papers and some 230 contributed four-page papers from the August 1996 conference, examining all aspects of probabalistic mechanics and structural reliability regarding assessment and design of structural, mechanical, marine, aerospace, geotechnical, and environmental systems. Emphasis is on concepts and methods of probability in the design of engineering systems, with particular focus on progress in stochastic mechanics in earthquake engineering, structural dynamics, and finite element methods.
