Condition assessment techniques used for non-building structures - Emphasis on measurement techniques

This paper attempts to summarize common condition assessment techniques, focusing on 'bridges' and 'historic monuments' and giving brief examples of condition assessment and measurement techniques from previous projects. Bridges have special importance among other civil engineering structures not only because they are the weakest chain links of an operational transportation system, but also they have demanding loading conditions of truck traffic, cyclic temperature, dynamic loading, and harsh environmental conditions (e.g. freezing and thawing, salting etc.). Condition assessment techniques are spread over a wide range from visual inspection to changing the bridge to an on-site laboratory.

Integration of practical supplemental measurements into bridge condition visual inspection grading
Shabana, Nefize; Avsar, Ozgur; Caner, Alp (2020-01-01)
The reliability of condition assessment of bridges obtained from analysis of visual inspection data is always a big concern among structural engineers. It has been known that the condition grading of a bridge is very subjective and can convey limited information to the end user. To finalize and verify the reported condition grading, inspectors and bridge owners have mainly been relying on images. It has been known that the image observation may not be sufficient to address all kinds of problems associated w...
Quantitative approach to rapid seismic evaluation of slab-on-girder steel highway bridges
Dicleli, Murat (1996-01-01)
A quantitative approach follows for developing a methodology for the rapid seismic evaluation and ranking of slab-on-girder steel highway bridges. In the development of this methodology, analytical expressions are introduced to calculate the seismically induced forces and displacements in bridge components, first assuming that damage to bearings is not acceptable and then removing this constraint. In the latter case, the superstructure is assumed to become unrestrained and slide on its supports. The seismic...
Structural identification-based condition assessment: A demonstration of methods applied to a laboratory scale model testbed
Helmicki, A.; Lenett, M.; Greisman, A.; Türer, Ahmet; Hunt, V.; Aktan, A.e. (null; 1999-12-01)
This paper reports on results from an ongoing project to study structural identification-based approaches to the condition assessment of constructed facilities. Under such an approach baseline and sequentially identified system models would be used comparatively to track changes in system parameters and to infer the onset, location, and extent of structural damage, deterioration, and/or defects. As part of the initial phases of this research a scale model grid representing a steel girder highway bridge was ...
Failure mode response functions in reliability-based design of rubble-mound breakwaters
Ergin, A; Balas, CE (1997-05-30)
The reliability-based model applied in this paper, provides a valuable tool in the design of coastal structures which are characterized by large failure consequences and substantial capital expenditures. Therefore, the implementation of the model to the design of rubble-mound breakwaters has an utmost importance especially in countries such as Turkey, where the use of natural stone for breakwaters is very common due to its economy. The purpose of the present paper is to describe the model by implementing it...
Vulnerability assessment of reinforced concrete moment resisting frame buildings
Erduran, Emrah; Yakut, Ahmet (2007-04-01)
A detailed seismic performance assessment procedure has been developed for reinforced concrete (RC) frame buildings with masonry infill walls. The procedure is based on member damage functions, in terms of interstory drift ratios. These functions are developed for the primary components, namely, columns, beams, and infill walls. For developing these functions, analytical investigations to determine the influence of several parameters on the damageability of components were combined with experimental data. A...
