This process can result in a delay of weeks or months between damage and failure detection
During this time, the fault may spread further, making repairs more difficult and expensive

Embodiment Construction

[0043] Methods, systems and software for assessing the integrity of one or more joints of civil structures will now be described. The method provides the ability to monitor the structural health of civil structures in real time.

[0044] figure 1 A simplified side view of a civil infrastructure 100, in this case a bridge, is illustrated. It will be appreciated that the method is equally applicable to any structure, whether public or private, that has one or more joints. Examples are dams and buildings. A joint is any two or more substructures of a structure that are in contact with each other and generally exert a force on one or more other substructures at that joint. Substructures can be regular discrete components of a structure, such as individual beams. Alternatively, the substructures may be less formal discrete components, eg different parts of the same component of a structure (substructures), eg different parts of the same beam, as defined by cracks or voids in th...

Abstract

This disclosure relates to the integrity of a civil structure, and in particular the assessment of the integrity of one or more joints of a civil structure. Two or more sensors (200a) and (200b) are provided on different substructures (102) and (106) that form the structural joint (112), wherein each sensor (200a) and (200b) generates sensor data associated with the substructure that that sensor is provided on. A measure of similarity is determined between the sensor data. The integrity measure of the structural joint is based on the measure of similarity. The method exploits the finding that when a joint is stressed and healthy (and inturn has good structural integrity), sensed movement of each substructure that forms the joint is substantially similar, such as in frequency or amplitude. Other aspects of the invention include software and a computer implemented method.

Description

technical field [0001] The present disclosure relates to the integrity of civil structures, and more particularly to the integrity assessment of one or more joints of civil structures. Aspects include computer-implemented methods, software, and computer systems. Those skilled in the art will understand computer systems and software design. Background technique [0002] Civil structures are usually large structures and often public works such as bridges, dams or buildings. [0003] Civil structures have joints between structural subassemblies of the structure (substructure). Over time, these joints lose some of their integrity as a result of weathering, decay and corrosion. In order to preserve the integrity of the structure, early detection of deterioration and execution of appropriate maintenance (preventive and / or reactive) are preferred. [0004] Detection is usually detected by periodic visual inspection or by observing the consequences of loss of integrity, such as ...
