Seismic Damage Analysis of Frame Structures Spanning Ground Fissures Based on Neural Network
To carry out structural damage analysis on structures under special geological conditions
a five-story frame structure spanning the f4 ground fissure in Xi'an was taken as the research object. Based on the results from shaking table tests and ABAQUS finite element analysis
a BP neural network model was trained. A two-parameter damage model combining deformation and energy was employed to calculate structural damage index. The weighted coefficient method was used to carry out the damage prediction analysis of components
floors
and structures
providing evaluations of structural damage under different seismic impacts. The results showed that the structure on the ground fissure site exhibited a significant hanging-wall/footwall effect
with the first layer being the weak layer. The BP neural network's damage prediction values closely aligned with the finite element calculation values across different conditions. The maximum prediction errors for components
inter-layer
and overall structural damage indices were 8.86%
5.66%
and 7.57%
respectively.
