Shear behaviour of steel-fibre-reinforced concrete simply supported beams

The structural behaviour of steel-fibre-reinforced concrete beams was studied using non-linear finite-element analysis and existing experimental data. The work aim was to examine the potential of using steel fibres to reduce the amount of conventional transverse steel reinforcement without compromising ductility and strength requirements set out in design codes. To achieve this, the spacing between shear links was increased while steel fibres were added as a substitute. Parametric studies were subsequently carried out and comparisons were also made with BS EN 1992-1-1 predictions. It was concluded that the addition of steel fibres enhanced the load-carrying capacity and also altered the failure mode from a brittle shear mode to a flexural ductile one. The provision of fibres also improved ductility. However, interestingly it was found that adding excessive amounts of fibres led to a less-ductile response. Overall, the study confirmed the potential for fibres to compensate for a reduction in conventional shear reinforcement.

Difficulties generating self-compassion: An interpretative phenomenological analysis

The aim of the present study was to make an idiographic investigation about the difficulties that are encountered by people who self-identify as having difficulties with self-compassion. Although a growing number of studies have been carried out concerning the concept of self-compassion, most research designs were quantitative. Based on this gap, the current study expanded the scope to include a qualitative dimension of the recent literature on self-compassion and Interpretative Phenomenological Analysis (IPA) was adopted as methodological preference, which particularly monitors the lived experience of participants. In consequence of four in-depth semi-structured interviews, four super-ordinate themes emerged; the double-edged-sword: perfectionism, the flaws of compassion, the effects of a third person, and the advantages of self-criticism. In line with pre-existing research, these findings explored the reasons behind self-undermining behaviours and misconstructions about self-compassion, which are a barrier to gentle self-talk. Furthermore, unfavourable effects of the social environment prime participants to maladaptive perfectionism and excessive self-criticism, which are considered a success formula by the participants. This study's purpose is to present a detailed roadmap about the self-destructive journey of the people with low self-compassion. It will help researchers and clinicians to develop future interventions in order to cultivate kind and encouraging attitudes in self-critical people.
