In recent years, concrete having a compressive strength of 60 MPa and more is being used for high-rise buildings and long span bridges, but high strength concrete is more expensive than normal strength concrete and became commercially used in engineering construction. This material has to be placed where it should be in order to get an economical consideration. This study introduces analyses of a new two layers reinforced concrete beam where high strength concrete in the compression zone and normal strength concrete in the tension zone are assumed based on experiences of previous laboratory. The beam specimens were solved numerically using nonlinear finite element program provided by ABAQUS 6.12 software for static load to verify the same using experiment. An agreement between analysis and experimental results was obtained, and less than 11.4% has been put as acceptable limit.
