Abstract [en]

This study is concerned with the blast effects on reinforced concrete (RC) connections. The RC connections are analysed nonlinearly. The analyses are conducted by applying the finite element software ABAQUS. The first step is to do the verification of the modelling. To achieve this goal, an experimental test performed on an RC connection is simulated utilising ABAQUS. Comparing the analysis result with the experimental test result establishes the modelling verification. In the second step, a 5-storey building is designed by the use of the ETABS software. A connection of the ground floor is selected for further analyses in ABAQUS. In the third step, the components of the selected connection are designed. Then, various variables are taken into account as the distance of the connection from the blast centre (2.5 m, 5 m, and 10 m) and the blast power (500 kg, 1000 kg, and 2000 kg TNT equivalent mass of explosive) for the further analyses of the connection. In the fourth step, the connection is analysed considering the variables. Finally, effects of these variables on the behaviour of the connection are investigated and discussed. Failure modes of the connections due to the blast loading are presented. © IJSTR 2019.
