Options can be added to expand analyses (dynamic, creep, and thermal) and to create user-defined constitutive models (UDMs). FLAC2D provides an incredibly accurate simulation of real-world geotechnical conditions for engineering applications, such as slope stability, underground excavation behavior, and earthquake simulations. Flexible commands and scripting allow for model parameterization, flexibility, customization, and automation.

To analyze the main structural characteristics of the building, including the fundamental frequencies and modes, the fast Fourier transform (FFT) was used to transform time series data from the time domain to the frequency domain. As the fundamental frequency is proportional to k, where k represents the global stiffness of the structure, the analysis results were used as the preliminary index to determine whether the structure was damaged due to earthquakes or human use. The FFT results for the reference condition are illustrated in Figure 6b. The main frequencies of the structure were lower than 10 Hz. The first fundamental frequencies in the X- and Y-axes were 1.644 Hz and 2.147 Hz, respectively. These FFT results indicate that the structure was stronger in the Y-axis than it was in the X-axis. According to a previous study on CMSCE, the following parameters were set to analyze the health status of the structure: sample dimension (m) = 4; threshold value (r) = 0.08; and sample length (L) = 2500 points. The analysis results are displayed in Figure 6c. As indicated by the reference CMSCE diagram, the trends of the structural health characteristics were uniformly distributed among the various floors, thereby demonstrating the feasibility of applying the reference data for long-term monitoring.
FLAC3D is the best solution to solve complex geotechnical problems for three-dimensional analyses of soil, rock, concrete, structural ground support, and groundwater flow. Options can be added to expand analyses (dynamic, creep, thermal, and IMASS) and to create user-defined constitutive models (UDMs). FLAC3D 9 has an improved user interface (UI) and new interactive tools to construct and interpret models easily. FLAC3D provides an incredibly accurate simulation of real-world geotechnical conditions for engineering applications, such as slope stability, underground excavation behavior, and earthquake simulations. Flexible commands and scripting allow for model parameterization, flexibility, customization, and automation.
