Development of the 2005 Edition of the Australian/New Zealand Standard for Cold-Formed Steel Structures AS/NZS 4600

Abstract: The paper describes the new developments in the Australian/New Zealand standard AS/NZS 4600. The developments are based mainly on research in Australia and the USA. They include new rules for high strength steel, the new Direct Strength Method of design as an alternative to the Effective Width Method and many other detailed changes including design of unstiffened compression elements under stress gradient. The standard is based mainly on the North American Specification published in 2001 with a 2004 Supplement but with special rules for high strength steels as produced in Australia including rules for distortional buckling and welding of high strength steel.

Quality Assessment of Unmanned Aerial Vehicle (UAV) Based Visual Inspection of Structures

Abstract: This paper discusses the application of Unmanned Aerial Vehicles (UAV) for visual inspection and damage detection on civil structures. The quality of photos and videos taken by using such airborne vehicles is strongly influenced by numerous parameters such as lighting conditions, distance to the object and vehicle motion induced by environmental effects. Whilst such devices feature highly sophisticated sensors and control algorithms, specifically the effects of fluctuating wind speeds and directions affect the vehicle motion. The nature of vehicle movements during photo and video acquisition in turn affect the quality of the data and hence the degree to which damages can be identified. This paper discusses the properties of such flight systems, the factors influencing their movements and the resulting photo quality. Based on the processed data logged by the high precision sensors on the UAV the influences are studied and a method is shown by which the damage assessment quality may be quantified.

Axial Loading Behavior of CFRP Strengthened Concrete-Filled Steel Tubular Stub Columns

Abstract: This paper presents the axial compression test results of concrete-filled steel tubular (CFST) stub columns strengthened with carbon fiber reinforced polymer (CFRP) composites. Both circular and rectangular specimens were tested to investigate the retrofitting effects of CFRP composites on them. The test results showed that the CFRP jackets enhanced the load bearing capacity of the circular columns effectively, whereas the enhancement was not so significant for rectangular columns. However, ductility was enhanced to some extent for those rectangular columns. A simple model is proposed to calculate the ultimate strength of circular CFST stub columns wrapped with CFRP. The predicted results are generally in good agreement with the experimental ones obtained in this study and in the literature.

Review of the current practices in blast-resistant analysis and design of concrete structures:

Abstract: In contemporary society, industrialization and rising of terrorism threats highlight the necessity and importance of structural protection against accidental and intentionally malicious blast loads. Consequences of these extreme loading events are known to be catastrophic, involving personnel injuries and fatalities, economic loss and immeasurable social disruption. These impacts are generated not only from direct explosion effects, that is, blast overpressure and primary or secondary fragments, but also from the indirect effects such as structural collapse. The latter one is known to be more critical leading to massive losses. It is therefore imperative to enlighten our structural engineers and policy regulators when designing modern structures. Towards a better protection of concrete structures, efforts have been devoted to understanding properties of construction materials and responses of structures subjected to blast loads. Reliable blast resistance design requires a comprehensive knowledge of blast ...

State-of-the-art review on bridge weigh-in-motion technology

Abstract: Weigh-in-motion technology is an effective tool that has been extensively used to monitor traffic on highways. Pavement-based weigh-in-motion systems usually have poor durability and will cause traffic interruption during their installation and maintenance process. The recently developed bridge weigh-in-motion technology provides a more convenient and cost-effective alternative to the pavement-based weigh-in-motion technology. Bridge weigh-in-motion systems can be installed without interrupting the traffic. Also, bridge weigh-in-motion systems have the potential to deliver better accuracy than pavement-based weigh-in-motion systems. Due to these significant advantages, the bridge weigh-in-motion technology has been playing an increasingly important role in bridge health monitoring and overweight truck enforcement, and many studies have been conducted to continuously improve the bridge weigh-in-motion technology. In this review, the common algorithms for bridge weigh-in-motion are discussed in detail, and ...
