Abstract

 

Indonesia is a country that is prone to earthquakes. Many houses or buildings in Indonesia are built using reinforced concrete material. Shear damage to reinforced concrete elements is very dangerous, because this damage occurs suddenly and usually occurs explosively. The nonlinear three-dimensional finite element analysis of self-compacting concrete beam and high strength concrete beam by mechanical compaction were carried out using the MSC Marc/Mentat software. Steel is modeled by being embedded in concrete. The Mohr-Coulomb Linear failure criterion is used for concrete and Von Mises for reinforcing steel. The results of the load- deflection curves for both self-compacting and mechanical compaction high-strength concrete beams are almost the same as those of the experimental curves in the elastic area, after elasticity, the analysis curve differs slightly from the experimental curve. The results of the theoretical analysis of the strength of the concrete are almost the same as the results of the analysis of the finite element concrete beams without reinforcement. The results of the contact analysis also showed that there was contact and detachment in the contact area of the load bearing steel and the beam support with the concrete.

 

Keywords: self-compacting concrete, high strength, finite element, MSC Marc/Mentat
