Dependência estrutural da capacidade de rotação plástic em vigas de concreto armado

Summary In this work the structural dependence of plastic rotation capacity in RC beams is evaluated using the Finite Element Method. The objective is to achieve a better understanding of the non-linear behavior of reinforced concrete members and perform extensive parameter studies, using a rational model developed by Bigaj [1] to analyze the phenomenon of plastic rotation capacity in reinforced concrete members. It is assumed that only bending failure is relevant due to sufficient member resistance against shear and torsion. The paper begins with the physical and theoretical background of the phenomenon of plastic hinge development in RC structures. Special emphasis is laid on the issue of structural dependence of deformation capacity of plastic hinges in RC members. Member size dependence and influence of properties of construction materials were emphasized as well. The essential components of the Bigajs model for calculating the plastic rotation capacity are discussed. The behaviour of the plastic hinge is analysed taking into account the strain localisation in the damage zones of the hinge region. The Fictitious Crack Model (FCM) and the Compressive Damage Zone Model (CDZ) are adopted in a Fracture Mechanics approach to model the behaviour of concrete in tension and compression, respectively. The approach is implemented in FEMOOP, a FEM in-house solver under development, and applied to evaluate ductility in 2D beams. The models were generated with GiD, a pre-processor and post-processor developed by CIMNE, and analyzed with the capabilities implemented in FEMOOP. © Universitat Politècnica de Catalunya, Barcelona, España 2010.

Grau de dependência de idosos hospitalizados para realização das atividades básicas da vida diária1

This study aimed to identify the level of dependence in elderly inpatients when performing Basic Activities of Daily Living. This quantitative, cross-sectional, descriptive study was conducted in the Adult Ward of the Botucatu University Hospital Emergency Unit - UNESP, Brazil. Data was collected by means of interviews, observation, and individual medical chart consultation, to be analyzed via logistic regression using the statistical software package SAS for Windows, version 9.2. The sample consisted of 71 subjects with a mean age of 74.30 years. It was observed that 30.99% of the older individuals showed to be independent in performing the proposed activities; 22.53% were partly dependent; and 46.48% were fully dependent. Gerontology care must aim at maintaining functional conditions, thus promoting independence and preserving these individuals' dignity.
