Impactos socioespaciais do uso e ocupação do solo urbano na área de entorno do Aeroporto Internacional de São Paulo - Guarulhos - Andre Franco Montoro

The construction of the São Paulo International Airport in Guarulhos recorded significant economic growth for the whole region, especially for services and jobs generated. Despite the importance of its presence in Guarulhos, we note the absence of an articulate and committed planning to urban development of the city, mainly in adjacent areas to this airport system planning. Through this stud, we analyzed primarily the major interferences and modifications afforded by its presence in guarulhense spatiality. We found that the government was, to some extent, tolerant to mounting housing in the surrounding area to the airport, from the moment that allowed the diverse urban land use in the place where it was planned to build such equipment. We further note that the airport is developed autonomously to the municipality in which the investments and related works only aim to meet the needs of the enterprise

Análise de características físicas de agregados de resíduos de construção e demolição, para fins de pavimentação

This work presents the results obtained in analyzes of aggregates from construction and demolition waste produced by the plant of the City of Guaratinguetá. Using this data and comparing with the specifications of NBR 15115, it was found that the materials do not possess the requisite minimum characteristics to be utilized as a basis for low-pavement traffic. In order to identify the main reasons of the material does not fit in the standard, we used the data obtained in a study conducted by Professor. Dr. Luiz Eduardo de Oliveira at the plant of the company AB Environmental Solutions Ltd., located in Pindamonhangaba. With different characteristics, the aggregates from construction and demolition waste produced by this plant showed the possibility of using pavements. The use of these residues in paving reduces the impact on the environment caused by construction.

Comparação de custo e viabilidade técnica de obras com parede de concreto em relação a obras de alvenaria estrutural

Are being released in the construction market in Brazil ventures called Super 6. These businesses sell the promise of delivery of the apartment in six months after the launch of the venture. To meet this deadline are being deployed the constructive method of concrete walls using aluminum shapes. This system basically consists of pouring slabs and walls once, i.e. building up the wall shapes and slab joints. On the walls are used cloth, with reinforcements in vain and corners of walls and on these screens are tied the electrical boxes and conduits. For each tower is used the so-called system of half way, i.e. the system so it is sufficient to mount the Middle deck. Using a concrete which can be deformed in the next day you can lift one deck every two days with ready electric and hydraulicsystem, without having to tow the wall doing only minor fixes in the imperfections after concrete. With this system won an incredible speed in the construction of the structure reducing in almost one-third the length of the work. This work aims to compare in terms of cost-benefit of masonry structural systems and this new concrete wall system called Super 6. For this comparison will be used as parameter values used for the achievement of the Enterprise Portal of Roses of constructor Tenda which is one of the first to use concrete wall system. This project basically consists of seven towers of six floors each and will be budgeted the cost of this project if it were held in structural masonry. From these data it will be possible to make a comparison about the actual beneficial to adopt this system

Potencial de aproveitamento de agregados reciclados de resíduos da construção e demolição

CONAMA Resolution 307 / 02, in Article 4, states that the primary goal of those involved in the reuse process of construction and demolition waste is not the generation of such wastes, secondarily is the reduce, reuse, recycling and proper disposal of such material. The disposal problem of large volumes of waste generated coupled with the scarcity of natural resources and environmental degradation involved in the extraction process of such materials resulted in several studies, that after many analyzes proposed various forms of reuse and recycling . The NBR 15.116/04 provides requirements for the use of recycled aggregates in paving and concrete without structural function. This work aims to show the usage potential of recycled aggregates from waste generated in construction and demolition sampled Group AB Areias, Pindamonhangaba (SP) in order to meet the standards in Brazil, as well as the environmental contribution by reducing the use of raw materials extracted from nature. After stabilization and particle size analysis of the California Bearing Ratio and Proctor, obtained mixtures of recycled aggregates showed higher values submitted by the minimum standards related, with excellent potential for use in paving

Estudo da concentração de material particulado em ambientes internos e externos de bibliotecas

Our twenty-first century society and the rhythm of life and work we have to face in our daily routine compel us to spend most of our lifetime in closed environments, in our houses, educational institutions, hospitals, airports, amongst as many others. The study of the air quality in internal environments (IAQ) is very important for monitoring people’s health effects and their environmental comfort in these locations. One essential parameter to analyze this measure is to evaluate the concentration of dispersed particulates in the air, specially focusing on those thinner particles (below the diameter of 2,5 μm), they can pose serious risks for human being because they can remain in the lungs, penetrate through the pores of our skin, amongst other harmful effects on human’s health. In this work the air quality inside the public library Profª Josina Vasques Ferrari and at Unesp public state library was evaluated, both located in Itapeva, as well as a third one, inside the Communitarian Library of the Federal University in Carlos (UFSCar) from march to may in 2012. In those environments it was analyzed if the concentration of particulates pose any real treat to the users. The equipment used for particle sampling in real time was DataRam 4 (Model DR 4000). The results given for those concentrations of particulates in both internal and external environments revealed figures within the safe standard established by the WHO (World Health Organization), from 25 to μg/m³, the only exception occurred on the fifth floor of the UFSCar library, where the average for concentration stayed at 25,30 of μg/m³

A cartografia geomorfológica como subsídio para a análise do relevo antropogênico em área de mineração

Mining activities are directly related to changes in natural landscapes. With the objective of analyzing the changes imposed by the geomorphological dynamics of human action in areas of mining clay, two fragments were selected from the basin of Ribeirão Santa Gertrudes / SP, representing denudational and sedimentation processes respectively. This area is within the context of the Ceramic Pole Santa Gertrudes / SP, which besides its importance as a supplier of raw material, is characterized as the largest center of international reference in ceramic tiles on the American continent. Data was collected and analyzed from the perspective of anthropogenic geomorphology supported by general systems theory and uses techniques from evolutionary geomorphological mapping. Thus, geomorphological mapping were produced concerning three scenarios, which date from 1962, 1988 and 2006 in a scale of 1:10.000. These surveys allowed us to infer a detailed investigation of the evolution of changes in topography and hydrology, geomorphology representative of the original (1962), which has characteristics of an earlier phase of earlier existing large mining pits, and its evolution to a anthropogenic geomorphological stage, represented by active disruption scenarios dating from 1988 and 2006. The last two scenarios have analyzed changes in the dimensions of relief features when compared with the original scenario representative of geomorphology, as well as an intense reallocation of surface and subsurface materials, in which human action is highlighted by becoming responsible for sculpting the landscape through the imposition of control mechanisms to natural processes.

A arquitetura habitacional social brasileira: propostas assertivas e inovações no âmbito dos institutos de previdência estatais do Século XX

No Brasil, a repetição descomedida de tipologias, partidos arquitetônicos e urbanísticos nos conjuntos residenciais sociais tomou vulto a partir da segunda metade da década de 1960, no âmbito do recém-criado Banco Nacional de Habitação (BNH). A produção desse órgão, até a década de 1980, é marcada pela disseminação do modelo da casa unifamiliar isolada no lote, com cobertura em duas águas, e pela perpetuação dos blocos com quatro pavimentos assentados diretamente no solo, com programas e plantas padrões implantadas sem levar em consideração os aspectos físico-climáticos e culturais locais. Essas unidades foram situadas em grandes conjuntos sem infraestrutura e/ou equipamentos coletivos, localizados, na maior parte das vezes, nas periferias das cidades. Porém, num momento anterior, mais precisamente entre as décadas de 1930 e 1960, os debates sobre a temática da moradia econômica e/ou mínima renderam ao país uma gama de propostas inovadoras, com destaque para as formulações e modelos pensados e concebidos pelos institutos de previdência, em especial, pelas Caixas e Institutos de Aposentadoria e Pensões (CAPs/IAPs). Nesse contexto, o presente artigo se propõe a apresentar as principais diretrizes que regeram as ações imobiliárias dos mencionadas instituições previdenciárias estatais no Brasil, bem como identificar e analisar algumas das inovações pensadas e concretizadas nesse sentido, muitas das quais foram relegadas a partir de 1964. Para tanto, tirar-se-á partido, sobremaneira, de dados primários relacionados à estruturação e à evolução dos regimentos e regulamentos das ações dos supracitados órgãos no campo da moradia, encontrados essencialmente nos arquivos jurídicos do país, bem como de pesquisa documental específica nos processos de financiamentos imobiliários concedidos aos trabalhadores urbanos brasileiros, ao longo das quatro décadas de atuação das CAPs e dos IAPs. O estudo destas vertentes, contextualizando-as no cenário das mudanças contemporâneas, conforma um esforço de compreensão da história da moradia social no Brasil, como também, das políticas públicas habitacionais no país.

Contribution to assessing the stiffness reduction of structural elements in the global stability analysis of precast concrete multi-storey buildings

This study deals with the reduction of the stiffness in precast concrete structural elements of multi-storey buildings to analyze global stability. Having reviewed the technical literature, this paper present indications of stiffness reduction in different codes, standards, and recommendations and compare these to the values found in the present study. The structural model analyzed in this study was constructed with finite elements using ANSYS® software. Physical Non-Linearity (PNL) was considered in relation to the diagrams M x N x 1/r, and Geometric Non-Linearity (GNL) was calculated following the Newton-Raphson method. Using a typical precast concrete structure with multiple floors and a semi-rigid beam-to-column connection, expressions for a stiffness reduction coefficient are presented. The main conclusions of the study are as follows: the reduction coefficients obtained from the diagram M x N x 1/r differ from standards that use a simplified consideration of PNL; the stiffness reduction coefficient for columns in the arrangements analyzed were approximately 0.5 to 0.6; and the variation of values found for stiffness reduction coefficient in concrete beams, which were subjected to the effects of creep with linear coefficients from 0 to 3, ranged from 0.45 to 0.2 for positive bending moments and 0.3 to 0.2 for negative bending moments.
