The New Australian Concrete Structures Standard AS 3600:2018 – Aspects of its Complexity and Effectiveness
No full textProviding design guides, the first of the AS 3600 standard series, Australian Standard for Concrete Structures AS 3600-1988 was published in March 1988. Since then, AS 3600 has been revised four times and published consecutively at between six to nine-year intervals as AS 3600-1994, AS 3600-2001, AS 3600-2009 and the latest, AS 3600-2018. The changes and/or updates made in AS 3600-2018 are mainly in the following requirements:
> Stress-block configuration for bending analysis and design of reinforced and prestressed members
> Shear and torsional strengths of members
> Values of capacity reduction factor, Ø, for different member strengths
> Effective moment of inertia for deflection calculations
Most of the abovementioned modifications have resulted in more complicated procedures and additional computational efforts. Academically, such added complexity might be considered as a disciplinary upgrade. On the other hand, the practitioners deserve to be advised of the effectiveness, or worthiness, of such an advance. In each of the concerned topics, analysis and design calculations have been carried out using the updated specifications given in AS 3600-2018, as well as those available in the superseded AS 3600-2009. Based on the numerical data and design outcomes, observations are made in this paper regarding the complexity and effectiveness of this the latest version of Australia’s premier concrete structures code.Full Tex
The New Australian Concrete Structures Standard AS 3600:2018 – Aspects of its Complexity and Effectiveness

The changes incorporated in AS 3600-2018 concern mainly the following topics:
1. Stress-block configuration for bending analysis and design of reinforced and prestressed members
2. Shear and torsional strengths of reinforced and prestressed members
3. Values of the strength capacity reduction factor, for different member strengths
4. Effective moment of inertia for deflection calculations
As part of a review, a summary of the relevant new design procedures and associated formulas have been prepared.
Research worldwide on the mechanics and strength of concrete structures – a rather mature discipline – is sustaining a state of diminishing return. Australia is no exception. In particular, the modifications identified above have led to more complicated processes which require increased computational efforts. Academically, such added complexity may be considered as a disciplinary upgrade. Concrete engineering practitioners, on the other hand, deserve to be advised of the effectiveness, or worthiness, of such an advance.
In each of the concerned topics and for practical problems, analysis and design calculations have been carried out using the updated specifications given in AS 3600-2018, as well as those existing in the superseded AS 3600-2009. Based on the analysis results and design outcomes, observations are made in regard to the complexity and effectiveness of this Australia‟s premier concrete structures code.Full Tex
Moral Values in Novel 3600 Detik: Literary Pragmatics Study
No full textThe problem raised in this study is how the form of delivery of moral values used by the author, the moral values contained in the main character in dealing with problems and the form of moral values contained in the novel 3600 Detik by Charon. The purpose of the study is to describe the form of conveying moral values used by the author, the moral values contained in the main character in dealing with life's problems and the form of moral values contained in the novel 3600 Detik by Charon. The approach used in this research is a theoretical approach (literary pragmatic theory) and methodological approach (qualitative descriptive approach), and is studied using literary pragmatic studies. The method uses content analysis method. The data source is the novel 3600 Seconds by Charon. The data collected is in the form of words or quotes. Data collection techniques in the form of library techniques. Data validity techniques are focused on two ways, namely increasing persistence and using reference materials. The results of the study concluded that the form of moral delivery consists of two components, namely direct delivery which is conveyed through the author's description and through characters and indirect delivery which is conveyed through events and conflicts in the novel 3600 Detik. The moral values contained in the main character in dealing with life's problems in the 3600 Seconds novel consist of five variants, namely disobeying school rules, caring for friends, never giving up, being firm and being honest. The form of moral values contained in the 3600 Seconds novel consists of three aspects, namely the form of moral values in human relations with God, forms of moral values in human relations with humans and forms of moral values in human relations with oneself.
 
The liquid-argon scintillation pulseshape in DEAP-3600
No full textDEAP-3600 is a liquid-argon scintillation detector looking for dark matter. Scintillation events in the liquid argon (LAr) are registered by 255 photomultiplier tubes (PMTs), and pulseshape discrimination (PSD) is used to suppress electromagnetic background events. The excellent PSD performance of LAr makes it a viable target for dark matter searches, and the LAr scintillation pulseshape discussed here is the basis of PSD. The observed pulseshape is a combination of LAr scintillation physics with detector effects. We present a model for the pulseshape of electromagnetic background events in the energy region of interest for dark matter searches. The model is composed of (a) LAr scintillation physics, including the so-called intermediate component, (b) the time response of the TPB wavelength shifter, including delayed TPB emission at O(ms) time-scales, and c) PMT response. TPB is the wavelength shifter of choice in most LAr detectors. We find that approximately 10% of the intensity of the wavelength-shifted light is in a long-lived state of TPB. This causes light from an event to spill into subsequent events to an extent not usually accounted for in the design and data analysis of LAr-based detectors
