Optimal finite element model with response surface methodology for concrete structures based on Terrestrial Laser Scanning technology

Abstract Terrestrial Laser Scanning (TLS) technology, which is hailed as another technological revolution in the field of surveying and mapping, is well known as a structural deformation monitoring device for concrete structures. In the current paper, we frame the finite element model (FEM) of concrete structure based on three-dimensional TLS technology and optimize the model by response surface methodology (RSM). It is theorized and confirmed that volume-based FEM model will be more precise than the displacement-based model, due to that the distortion of specimen is considered with the benefit from volumetric analysis when composite structures is distorted with loads.
