Part 11 - Spectral Wind Fatigue SACST 培训教材.pdf

Part 11 - Spectral Wind Fatigue Preparation 1) Under “Training Project”, create “Spectral Wind Fatigue” subdirectory 2) Under “Spectral Wind Fatigue”, Create “Foundation SE”, “Modes” and “Wind Fatigue” subdirectories. 3) Copy SACINP.STA model file, SEAINP.STA and PSIINP.DAT soil data from “\Spectral Earthquake\Static SE” directory to “Foundation SE” directory. Creating foundation superelement under “Foundation SE” directory, 1) Modifying Seastate file SEAINP.STA Delete EQKS from LCSEL and load combinations. Rename load case GRVX to X000: delete ACCEL line and modifying INCWGT to include only ANOD and WKWY for possible wind loads. Add 000 direction wind at 15.0 m/sec @ 10 m, using AP08 for wind profile. Rename load case GRVY to Y090: delete ACCEL line and modifying INCWGT to include only ANOD and WKWY for possible wind loads. Add 090 direction wind at 15.0 m/sec @ 10 m, using AP08 for wind profile. In load combinations using X000 to replace GRVX and Y090 to replace GRVY.
