Study on an Optimal Strut-And-Tie Model for Concrete Deep Beams

open access: yesApplied Sciences, 2019
The optimal strut-and-tie models (STMs) of two typical irregular concrete deep beams were constructed using evolutionary structural optimization and compared with those of previous studies.

Skeletons of swiftly swimming sharks: Three‐dimensional analysis of lamniform vertebral morphology and mineral architecture

open access: yesJournal of Anatomy, EarlyView.
We examined morphology, 3D arrangement, and mineral amount in cartilaginous vertebrae from four lamniform shark families (Alopiidae, Carchariidae, Cetorhinidae, and Lamnidae). We identified family‐specific mineralization trends, and regional patterning of structures along the column.

Experimental evaluation of optimized strut‐and‐tie models for a dapped beam

open access: yesStructural Concrete, 2016
AbstractStrut‐and‐tie modelling constitutes a powerful tool for the design of complex structural reinforced concrete elements. It has been proved numerically that strut‐and‐tie (ST) models obtained using structural optimization methods produce designs that are more efficient.

The impact of footwear on human talar trabecular architecture

open access: yesJournal of Anatomy, EarlyView.
Medial and lateral views of the human foot skeleton in the shod and unshod groups, with color maps representing mean relative trabecular bone volume fraction (rBV/TV) in the talus for each group. The shod group exhibited greater rBV/TV in the medial and posterior talus, whereas the unshod group had greater rBV/TV in the talar head and neck.

International Conference on Mechanics of Structures, Materials and Systems (1999) [PDF]

open access: yes, 1999
This paper deals with the topology optimization of strut-and-tie models in non-flexural reinforced concrete members by using the Evolutionary Structural Optimization (ESO) method for plane stress continuum structures with displacement constraints.

Structural Design and Technology of Pocket Foundations for Long Precast Concrete Columns in Seismic Areas

open access: yesBuildings
The connection between a prefabricated reinforced concrete column and a pocket foundation is a case treated from a general perspective in the European Standard named EN 1992-1-1 (EC2), and when the structural engineer deals with the dimensioning or ...

Secrecy: An Epistemological Account

open access: yesNoûs, EarlyView.
ABSTRACT Although the ethical and political implications of secrecy are significant, I argue here that its fundamental nature is epistemological and that any account of its nature must be based on its epistemological profile. In particular, I propose examining secrecy within the framework of social and political epistemology, considering secrets as ...

Seriality and style: The embodiment, perception, and normalization of collectives

open access: yesThe Southern Journal of Philosophy, EarlyView.
Abstract Within existential phenomenology, both seriality and style have been drawn on to theorize the embodiment and perceptibility of (social) ontological differences. While style refers to how we encounter the world and others not in the abstract, but as immediately and intuitively meaningful, seriality is a form of collective being that pertains to

Shear force and torsion in reinforced concrete beam elements: theoretical analysis based on Brazilian Standard Code ABNT NBR 6118:2007

open access: yesRevista IBRACON de Estruturas e Materiais
Reinforced concrete beam elements are submitted to applicable loads along their life cycle that cause shear and torsion. These elements may be subject to only shear, pure torsion or both, torsion and shear combined.
