Resumo: | In this dissetation exploratory models are used to examine the behavior of semi - rigid pillar - beam connections with shear key. This type of connection is ordinary in Brazil prefabricated concrete structures. Thus, the use of a solenoid, shear key between the pillar - beam face and the addition of negative reinforcement on the cap rod, being this at the top of the beam, gives the connection a semi - rigid behavior and the possibility of transferring vertical actions relieving the amount of effort in the console. The work contributes to verify the structural situation and the representativeness of the connections already performed in Brazil, since there are no studies or tests carried out to verify the real influence of impact of the shear key assists in the composition of the bond. The study consisted in the creation of a simple model, based on long-term experiments in Brazil for semi-rigid connections. Through the tests, it was verified the efficiency of the participation of the shear key, where they were considered models of real magnitude. This study will serve as a basis for the later realization of joint geometry variation, as well as the real problem in beams with large deformations. The study is finished by isolating the total portion resisted by the semi-rigid connection by discounting the value resisted by the pin effect of the negative rod and the portion of stresses resisted by the console, in this way it was determined that the shear key actually had a relief effect of 40,88% of the total amount of efforts. |

Esse tipo de ligação é comum no Brasil em estruturas pré-fabricadas de concreto. Assim, a utilização de consolo, chave de cisalhamento entre a face pilar-viga e com a adição de armadura negativa no tirante do capeamento, sendo este na parte superior da viga, dá a ligação um comportamento semirrígido e a possibilidade de transferência de ações verticais aliviando a parcela de esforços no consolo. O trabalho contribui para averiguar a situação estrutural e a representatividade das ligações já executadas no Brasil, uma vez que não existem estudos nem ensaios realizados para constatar a real influência de quanto a chave de cisalhamento auxilia na composição da ligação. O estudo consistiu na confecção de um modelo simples, baseada em experiências executadas de longa data no Brasil para ligações semirrígidas. Através dos ensaios, verificou-se a eficiência da participação da chave de cisalhamento, onde foram considerados modelos de real grandeza. Este estudo serve como base para uma posterior realização da variação da geometria das juntas, bem como a real problemática em vigas com grandes deformações. O estudo foi finalizado isolando a parcela total resistida pela ligação semirrígida, descontando o valor resistido pelo efeito pino da barra de tirante negativo e a parcela de esforços resistida pelo consolo. Dessa maneira, determinou-se que a chave de cisalhamento realmente teve um efeito de alívio de 40,88% da parcela total de esforços.Não recebi financiamentoporUniversidade Federal de São CarlosCâmpus São CarlosPrograma de Pós-Graduação em Engenharia Civil - PPGECivUFSCarLigação semirrígidaChave de cisalhamentoLigação pilar-vigaPré-fabricados.Semi-rigid connectionShear keyColumn-beam connectionPre-fabricated.PrecastENGENHARIAS::ENGENHARIA CIVIL::CONSTRUCAO CIVIL::PROCESSOS CONSTRUTIVOSENGENHARIAS::ENGENHARIA CIVIL::CONSTRUCAO CIVILENGENHARIAS::ENGENHARIA CIVIL::ESTRUTURASENGENHARIAS::ENGENHARIA CIVILENGENHARIAS::ENGENHARIA CIVIL::ESTRUTURAS::ESTRUTURAS DE CONCRETOEstudo experimental dos mecanismos resistentes de juntas com chave de cisalhamento em ligações pilar-vigaExperimental study of the resistant mechanisms of the shear key joints in column-beam connectionsinfo:eu-repo/semantics/publishedVersioninfo:eu-repo/semantics/doctoralThesisOnlineinfo:eu-repo/semantics/openAccessreponame:Repositório Institucional da UFSCARinstname:Universidade Federal de São Carlos (UFSCAR)instacron:UFSCARORIGINALFaleiros Junior, J.H - 2018.pdfFaleiros Junior, J.H - 2018.pdfapplication/pdf13081975https://{{ getenv "DSPACE_HOST" "repositorio.ufscar.br" }}/bitstream/ufscar/10577/1/Faleiros%20Junior%2c%20J.H%20-%202018.pdff8568b88e486bcb6aa946a146608ac4fMD51LICENSElicense.txtlicense.txttext/plain; charset=utf-81957https://{{ getenv "DSPACE_HOST" "repositorio.ufscar.br" }}/bitstream/ufscar/10577/3/license.txtae0398b6f8b235e40ad82cba6c50031dMD53TEXTFaleiros Junior, J.H - 2018.pdf.txtFaleiros Junior, J.H - 2018.pdf.txtExtracted texttext/plain249278https://{{ getenv "DSPACE_HOST" "repositorio.ufscar.br" }}/bitstream/ufscar/10577/4/Faleiros%20Junior%2c%20J.H%20-%202018.pdf.txt3ff05f11dda3170d81126028bd86ec29MD54THUMBNAILFaleiros Junior, J.H - 2018.pdf.jpgFaleiros Junior, J.H - 2018.pdf.jpgIM Thumbnailimage/jpeg6601https://{{ getenv "DSPACE_HOST" "repositorio.ufscar.br" }}/bitstream/ufscar/10577/5/Faleiros%20Junior%2c%20J.H%20-%202018.pdf.jpg429be439b8faa6d2a2294ddf0972da4fMD55ufscar/105772020-01-22 20:29:01.215oai:repositorio.ufscar.br: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Repositório InstitucionalPUBhttps://repositorio.ufscar.br/oai/requestopendoar:43222020-01-22T20:29:01Repositório Institucional da UFSCAR - Universidade Federal de São Carlos (UFSCAR)false |
