| Title: | Puncionamento de lajes protendidas |
| Author(s)/Inventor(s): | Carvalho, Eliane Maria Lopes |
| Advisor: | Maia, Antônio Cláudio Ferraro |
| Abstract: | Neste trabalho são apresentados os resultados dos ensaios de puncionamento de três lajes protendidas com pilares interiores e sem armaduras transversais. Variou-se a tensão de protensão aplicada, a resistência à compressão do concreto e as dimensões dos pilares. Os resultados experimentais da carga de ruptura por puncionamento foram comparados com valores teóricos obtidos a partir dos métodos de cálculo propostos pelas normas NB-1/78 e ACI/77 e pelas recomendações do CEB-FIP/78. |
| Abstract: | In this work it is presented the results of punching tests in three plat slabs. These slabs were supported on a central column and had no shear reinforcement. The parameters varied in them were the prestress applied, the compressive strenght of the concrete and the dimensions of the cross-section of the column. The puching failure loads obtained in the tests are compared with predicted values found from the formulas given by the NB-1/78, ACI/77 and CEB-FIP codes of practice. |
