Resumo: | Edge protection systems are used to prevent accidents caused by work at height in building construction. The importance of the occupational safety and its influence on costs and social damage caused by accidents in civil construction, justify measures to create effective preventionsystems. This subject continues to demand attention from the civil construction industry and from government, due to the increasingly occurrence of work accidents by fall from heights in buildings and infrastructure construction. In the field of guardrail structures used with this purpose, in Brazil the regulation NR-18, NR-35 and RTP 01 deal with it, however few is defined about the analysis and design of those systems. Some international standards, on the other hand, define some criteria beyond those used by Brazilian standards, especially about structural design. It´s observed that loads are different in the all consulted standards. In this research, it is compared the literally results specialized to the analysis with structures used to this purpose, using materials such as wood and steel and evaluating the results. To achieve these goals, numeric modellings were made through static analysis and explicit dynamic analysis using the Finite Element Method (FEM) simulating and analyzing the impact generated by a solid like human body and static loads, according to the standards in simplified guardrail models typically used for work safety. For the numerical models validation, it was made experimental tests, applying static charges and with impact in the structures. The numerical and experimental results obtained in the research shows that the structures are able to support and absorb the charges applied. However, it is necessary to develop a new specific test for these structures since the Brazilian regulation NBR 4718 (ABNT, 2018a), for definitive guardrails, were restricted and for this reason the structures are not able to attend some maximum values for displacement in some cases. Though, it is considered that the charges of 150 kgf/m for an impact test, required by MTE, is more efficient than one with 77kg and distant 20,38cm. Indeed, during numerical and experimental tests and static analysis of impact, it was no local or global rupture of the system. |

A importância da segurança ocupacional e sua influência nos custos e nos danos sociais provocados por acidentes na construção civil justificam medidas para criar sistemas de prevenção eficazes. Esse tema continua a demandar atenção da indústria da construção civil e do Estado, devido à ocorrência de acidentes de trabalho, por quedas de altura, que tornam-se cada vez mais frequentes na Construção Civil. No campo das estruturas de guarda-corpos usadas com esse objetivo, no Brasil, existem especificações de ações nas Normas NR-18, NR-35 e RTP 01, porém, há pouco sobre os métodos de modelagem, análise e dimensionamento. Já as normas internacionais determinam alguns critérios que ultrapassam os apontados em normas nacionais, principalmente sobre dimensionamento. Entretanto, analisouse que os valores de resistência divergem entre as normas consultadas. Com isso, buscou-se reunir o estado da arte na literatura especializada e analisar estruturas usuais para esses fins, com materiais como madeira e aço, avaliando a resistência dessas. Para atingir os objetivos, foram realizadas modelagens numéricas, por meio de análise estática e dinâmica explícita, por meio do Método de Elementos Finitos (M.E.F.), simulando e analisando o impacto gerado por um sólido similar ao corpo humano e cargas estáticas, conforme preconizam as normatizações em modelos simplificados de guarda-corpos, típicos para a segurança do trabalho. Para a validação dos modelos numéricos, foram realizados ensaios experimentais, aplicando cargas estáticas e de impacto nas estruturas. Os resultados numéricos e experimentais obtidos no trabalho, indicam que as estruturas estudadas foram capazes de atender os carregamentos aplicados e absorver o impacto gerado, porém é necessário que seja desenvolvido um método de ensaio específico para estas estruturas, visto que ao analisar as estruturas com as orientações da NBR 14718 (ABNT, 2018a), para guarda-corpos definitivos, estes foram mais restritos e por estes critérios as estruturas deixam de atender os deslocamentos máximos em alguns casos. Ainda, considera-se que o carregamento de 150 kgf/m, exigido pelo MTE, supera as exigências geradas por um impacto de um sólido com massa de 77 kg e distância de impacto de 20,38 cm. Ainda pode-se afirmar que nem nos modelos numéricos e nem no experimental, nas análises estáticas e de impacto, houve ruptura local ou global do sistema.Submitted by Mariana Freitas (marianafreitas@upf.br) on 2018-06-06T18:57:40Z No. of bitstreams: 1 2017DinianeBaruffi.pdf: 7625565 bytes, checksum: ce5ddf57eb8f0b730fab7698a75a3e78 (MD5)Made available in DSpace on 2018-06-06T18:57:40Z (GMT).

Edge protection systems are used to prevent accidents caused by work at height in building construction. The importance of the occupational safety and its influence on costs and social damage caused by accidents in civil construction, justify measures to create effective preventionsystems. This subject continues to demand attention from the civil construction industry and from government, due to the increasingly occurrence of work accidents by fall from heights in buildings and infrastructure construction. In the field of guardrail structures used with this purpose, in Brazil the regulation NR-18, NR-35 and RTP 01 deal with it, however few is defined about the analysis and design of those systems. Some international standards, on the other hand, define some criteria beyond those used by Brazilian standards, especially about structural design. It´s observed that loads are different in the all consulted standards. In this research, it is compared the literally results specialized to the analysis with structures used to this purpose, using materials such as wood and steel and evaluating the results. To achieve these goals, numeric modellings were made through static analysis and explicit dynamic analysis using the Finite Element Method (FEM) simulating and analyzing the impact generated by a solid like human body and static loads, according to the standards in simplified guardrail models typically used for work safety. For the numerical models validation, it was made experimental tests, applying static charges and with impact in the structures.
