Comparison and evaluation of web crippling prediction formulas

Since the use of end and load stiffeners is frequently impractical in thin-walled cold-formed steel construction, the webs of beams a.nd deck oay cripple due to the high local intensity of the load or reaction. In this report three different web crippling prediction formulations are compared with experimental results from five different sources. It is found that these web crippling formulas show considera.ble differences and do not give satisfactory results consistently

Mindfulness-based stress reduction among Emirati Muslim women

© 2016 Informa UK Limited, trading as Taylor & Francis Group. Explorations of mindfulness-based psychotherapeutic approaches are relatively scarce outside of Europe and North America. This study examined the effectiveness and the religio-cultural appropriateness/acceptability of a Mindfulness-based Stress Reduction (MBSR) programme among Muslim citizens of the United Arab Emirates. Emirati college women (N = 12) were enrolled in an eight-week, group-based, MBSR programme. After completing the programme, participants attended a focus group exploring their perceptions of MBSR, with a particular emphasis on exploring the cultural appropriateness of this approach. The MBSR programme was favourably evaluated, and not in any way deemed antithetical towards the participants\u27 own theistic or cultural traditions. The results are discussed with reference to identifying bridging concepts to help better contextualise MBSR for people who spontaneously couch their experiences in religious themes, or who explicitly express a desire for faith-affiliated interventions

FE Models for Sheeting under Interaction Load

Experiments show that, after ultimate load, sheeting may fail by three distinct post-failure modes. In this paper, three finite element models are presented, one for each post-failure mode. One of the finite element models was difficult to develop. A spring model explains this. The finite element models show that, at ultimate load, only two different ultimate failure modes exist. This is important for the development of mechanical models for sheeting failure

Ultimate Failure Behaviour of Second-generation Sheeting Subjected to Combined Bending Moment and Concentrated Load

Second-generation sheeting is widely used for cladding and roof construction. At interior supports, it is subjected to combined bending moment and concentrated load. Unfortunately, design rules for this loading are complicated and do not provide insight in the sheeting\u27s failure behaviour. This means there is a need for a new, insight providing design rule. For first-generation sheeting, a similar problem did exist. The Technische Universiteit Eindhoven (TUE) carried out three research projects [Bakk92a,Vaes95a,Hofm00a] that provided insight in the first-generation sheeting behaviour and resulted in a new, insight providing design rule. The TUE now uses the strategy of these three research projects for a new project on second-generation sheeting [Kasp01a], with the final aim of a new design rule for second-generation sheeting. In this new project, experiments on commonly used (in the Netherlands) second-generation sheeting were carried out. Second-generation sheeting behaviour was compared with first-generation sheeting behaviour. For sheeting with only stiffeners in flange, load falls occur before ultimate load. Stiffeners in the web only result in load falls after the ultimate load. For an experiment with only stiffeners in the web, a finite element simulation was made. The simulation predicts the sheeting behaviour fairly well and indicates how a stiffener affects the sheeting behaviour

Risk Analyses of Disposal of Pig Carcasses Smaller Than 40 KG in The Netherland

A study based on the literature, an on- farm audit and expert knowledge, was carried out to determine 1) the risks of spread of animal diseases among farms; 2) odour nuisance due to carcasses at the rendering plant; and 3) measurements to reduce these risks. It was concluded that the possible risks of spread of animal diseases among farms due to the removal of carcasses mainly has to do with the entrance of the place from where the carcasses are collected by the driver of the truck , the contact of the grab of the haulier with the cadaver container or place and driving with the haulier which is not fully closed. The true size of the risk of spread of disease is unknown and is probably different for each pathogen. Strict hygiene measurements by the driver and farmer can reduce the risk of spread of animal diseases due to cadaver removal. According to the interviewees at the expert assessment session, the odour nuisance at the rendering plant due to carcasses is mainly caused by bacterial conversion of proteins. Cooling of carcasses contribute to the slowing down of the conversions. No unambigious answer could be obtained as to the cooling temperature: not lower than -7°C because of the processing at the rendering plant and preferably not higher than 5°C. Frequent removal of carcasses from the farms and a quick handling at the rendering plant may also reduce odour nuisance at the rendering plant.Risk analyses, pig, carcasses, disposal, spread of disease, odour nuisance, pig farms, rendering plant, Livestock Production/Industries,
