Let's walk through a typical example: a 10-story reinforced concrete shear wall building subjected to the 1994 Northridge earthquake.
This is the most robust method for complex structures. It involves applying an acceleration time-history (an actual recording of an earthquake) directly to the model. abaqus earthquake analysis
After analysis, run *FREQUENCY extraction on deformed configuration to monitor period elongation – a key indicator of structural softening. Let's walk through a typical example: a 10-story
: 4-story RC frame subjected to El Centro 1940 NS (scaled to PGA=0.3g). abaqus earthquake analysis
