Evaluating the structural capacity of concrete elements through in-situ instrumentation

Evaluating the structural capacity of concrete elements through in-situ instrumentation
(2013)
Byrne, David; Goggins, Jamie
Abstract:
The difficulty in predicting the long term load capacity of concrete elements is well documented. Time dependent effects such as creep and shrinkage coupled with varying loading events, particularly during construction, can all have an adverse effect on the long term performance of a concrete structure. This paper proposes a method that utilises in-situ instrumentation to predict the load carrying capacity of concrete members. During the construction of the Engineering building at the National University of Ireland, Galway over 260 sensors were embedded in a number of key concrete elements. The sensors are being continually monitored with the use of automatic datalogging equipment and the data is being used to monitor changes in geometric and material properties along with the subsequent time dependent deterioration of the elements. The paper will illustrate how the in-situ data from the demonstrator building can be used to estimate the real time behaviour of the concrete elements a...

Real-time monitoring and performance of retaining structures
(2017)

Abstract:
The advent of reliable real-time monitoring devices has changed the way we monitor the construction of geotechnical infrastructure. This paper presents a case study where Shaped Accel Arrays (SAA) were employed as part of the real-time monitoring regime for the construction of two retaining structures that utilised a combination of secant and sheet piles. To improve their structural rigidity, a capping beam and horizontal props were employed. The retaining structures were erected to facilitate the launching and retrieval of a Tunnel Boring Machine (TBM). The monitoring regime detected structural sway and toe movement of the sheet pile walls. Adjustment methods for these effects are discussed within this paper, along with a comparative study between manual and real-time monitoring. Adjusting for the effects of sway and toe movement can considerably change the maximum deflection from that registered by an SAA, therefore, it is important to account for these effects when employing SA...
