Verificação de terceira ordem de estruturas de concreto armado de edíficios

The change in design of a building can occur during its construction process, especially when this change involves greater amount of profit for the building company, as it is the case of adding extra floors. However, there must be an analysis of the structure of the building in order to see if it is possible to increase the number of floors without the need of reinforcement, as this need would result in higher costs for the building company. This graduation report presents this analysis by using the methods of third order verification of reinforced concrete structures

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

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.

Trabalho e saúde: o cotidiano dos catadores de lixo reciclável

The present article is an investigation / action regarding the working conditions for pickers of recyclable waste in a medium-sized city in the state of São Paulo, mainly on the health / illness process, problems related to social security and conditions of autonomy and citizenship. We use the constructs of social psychology as theoretical. The recycling of urban garbage, as the literature indicates, is not being treated as just part of the solution to environmental problems, but also has been characterized as a source of income and livelihood for many people, with no other options in life. From the interviews were semistructured, and with the method of analysis the meaning core were identified issues related to the holding of by scrap collectors, prejudice existing in relation to the activity performed, poor housing conditions, the need to social recognition and the difficulty of recyclable garbage collectors in forming a group in which they can articulate and fight for their demands. With this study, we intended to indicate suggestions for improvements in these health professionals and encourage individual and collective reflections on the condition of meetings and also through the distribution of leaflets.
