Abstract: In the event of a seismic attack, the structural integrity of moment-resisting timber frames in the joint region may become compromised and hence the joint may not be able to transfer bending moment around the frame. Often, replacement of a damaged joint is not an option and hence efficient but effective strengthening and repair schemes for such joints are necessary. This article reports the results of 15 tests on 10 metal dowel-type moment-resisting timber connections subjected to monotonic or cyclic loading. Joints are either strengthened or repaired with epoxy, fibre-reinforced polymer composites or steel plates. The ability of the test joints to resist the imposed cyclic loading is presented in the context of hysteresis responses. Recommendations for strengthening and repair interventions are made based on strength, stiffness, ductility, energy dissipation and d ing characteristics of the test joints.

Abstract: Welded wire fabric (WWF) is commonly used in reinforced concrete (r.c.) slabs. WWF is classified in Australia as Class L or low ductility reinforcement and, as such, the characteristic strain at peak stress (termed the uniform elongation) is not less than 0.015 and the ratio of tensile strength to yield stress (0.2% proof stress) is not less than 1.03. A r.c. slab containing low ductility steel usually fails in bending by fracture of the tensile reinforcement at the critical section, well before the concrete in the compression zone becomes overstressed, and the conventional understanding of ductile under-reinforced flexural failure is not valid. The failure is brittle and results in complete collapse of the span, often with little or no warning. This paper explores the collapse load behaviour of slabs containing WWF, highlighting the great significance of strain localization in lightly reinforced slabs and its adverse impact on ductility. The results of tests on several simply-supported and continuous one-way slabs reinforced with WWF are used to illustrate the discussion.

Abstract: This paper reports an investigation on the influence of anchors made from fibre-reinforced polymer (herein FRP anchors) when applied to FRP-to-concrete bonds. The experimental section of the paper consists of 44 tests on FRP-to-concrete joints of which 20 joints are unanchored controls and 24 joints are anchored with FRP anchors. The influence of plate width, plate thickness and plate elastic modulus are considered as these parameters have received little to no attention to date. An increase in plate width is shown to considerably enhance the joint strength although the influence of the anchor decreases. The other two test parameters are shown to be less influential. The analytical section of the paper involves regression modelling of components of a large test database on FRP-to-concrete joints anchored with FRP anchors compiled elsewhere by the authors. The models, which are calibrated in best-fit and design forms, allow experimental trends to be readily observed and quantified within the bounds of the experimental data for three influential parameters of plate length, angle of anchor insertion, and plate width. Finally, a combined regression model is proposed and it is evaluated with tests on FRP-to-concrete joints anchored with multiple anchors.

Abstract: Fibre-reinforced polymer (FRP) anchors made from rolled or bundled fibres, which are known as FRP anchors amongst other names, are an emerging form of anchorage for application to externally bonded FRP strengthening systems. Little is however known of the fundamental behaviour of these anchors. This paper in turn reports the results of experiments on FRP anchors under pure tension (pullout) loading. A detailed description of the anchor construction procedure is firstly presented followed by anchor tensile strength test results. Pullout test results of FRP anchors embedded into uncracked concrete blocks are then reported with particular attention focused on the failure mechanisms, failure loads, bond strength and load-displacement and load-strain responses for varying anchor hole diameter, embedment depth and anchor fibre content. Finally, a large test data base is assembled from the results of the present study as well as two other studies found in the open literature. Relationships between the pullout load to the anchor diameter, embedment depth and concrete strength are identified while the effects of different methods of anchor construction are also discussed.

Abstract: Extensive research has been carried out in recent years on the use of fibre-reinforced polymer (FRP) composites in the strengthening of reinforced concrete (RC) structures. This paper provides a concise review of existing research on the behaviour and strength of FRP-strengthened RC structures, with a strong focus on those studies which contribute directly to the development of strength models. Topics covered include flexural and shear strengthening of beams, flexural strengthening of slabs, and strengthening of columns subject to both static and seismic loads. For each of the topics covered, the methods of strengthening are first explained, followed by a description of the common failure modes. Available strength models are then summarised and discussed.

Abstract: Reinforced concrete connections, designed prior to the implementation of earthquake design standards, may be vulnerable to shear failure during a seismic attack. Addition of externally bonded fibre-reinforced polymer (FRP) composites can enhance not just the shear capacity but the deformation and energy absorption capacity of the connection. The majority of research studies to date have opted for complete or near-complete coverage of the joint region with FRP and have subjected the test specimens to cyclic (push–pull) loading. Such strengthening schemes and method of loading make it quite difficult to accurately monitor and hence understand the behaviour of the FRP and the concrete beneath. This paper presents results of a series of tests on the strengthening of shear deficient connections with FRP strips subjected to either cyclic or monotonic loading with the primary motivation being accurate description of the behaviour of the FRP. The tests also enable the failure modes to be more accurately reported and classified especially due to the use of monotonic loading. An analytical model is finally presented which accurately describes the mechanics of the FRP strengthening with the model predictions correlating reasonably well with the test data.

Abstract: An effective means to increase the shear resistance of shear deficient reinforced-concrete (RC) beam–column connections is by bonding fibre-reinforced polymer (FRP) composites. The majority of research to date has focused on the strengthening of two-dimensional reinforced-concrete connections with fibre-reinforced polymer that is, the strengthening of virgin (undamaged) connections. This paper reports the results of tests on the effectiveness of fibre-reinforced polymer strips in repairing two-dimensional connections with different degrees of damage. The results of tests assessing the effectiveness of fibre-reinforced polymer strips in strengthening virgin connections are also reported. All test specimens are extensively instrumented and their behaviour and failure comprehensively documented. In the case of the repaired specimens, instrumentation is concentrated on the fibre-reinforced polymer around the damage region, thus enabling the strength contribution and behaviour of the fibre-reinforced polymer repair to be closely monitored. The results of this experimental programme enable a better understanding of the strengthening and repair effect of fibre-reinforced polymer strips in reinforced-concrete beam–column connections, and the results will also facilitate the future development and calibration of analytical and numerical models.

Abstract: The stiffness and strength properties of freshly poured concrete develop over time as the concrete hardens due to curing. The monitoring of such properties therefore enables timely construction decisions such as formwork removal. Traditional point-in-time destructive tests can be cumbersome, while continuous non-destructive testing is desirable. Piezoelectric-based electromechanical impedance (EMI) and wave propagation (WP) techniques fall into the latter, and they have been verified for monitoring concrete properties during curing in the laboratory. This paper reports the first field application of the EMI and WP techniques for monitoring concrete curing, where smart aggregate (SA) sensors are embedded into concrete pour strips of a multi-storey residential building during construction. For comparison and verification purposes, destructive compression and non-destructive ultrasonic pulse velocity (UPV) tests were conducted. Results obtained from both EMI and WP techniques were consistent and repeatable. They were also comparable to the UPV result, and they showed a close correlation to the compressive strength tests. The current study has also revealed that the electrical signatures acquired from the EMI and WP techniques have a linear relationship. EMI-based and WP-based semi-analytical models (and their derivations) that can quantify the compressive strength and modulus of elasticity of concrete at various curing durations are also presented. This reported study ultimately demonstrates the applicability and practical application of the EMI and WP techniques for real-time measurements, bridging the gap between laboratory-based studies and field applications.
