Part 10 - Extreme Wave SACST 培训教材.pdfVIP

Part 10 -Extreme Wave Preparation 1) Under “Training Project”, create “Extreme Wave” subdirectory 2) Under “Extreme Wave”, Create “Foundation SE”, “Modes” and “Dynamic Wave” 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. Delete load conditions GRVX and GRVY, add two new load conditions named as X000 and Y090, wave loads will be generated for 5.5 m wave height at 8.00 sec wave period for both 000 and 090 directions respectively. Stream function will be used for calculating wave force in 18 steps, maximum base shear will be selected for critical position. Still water depth override 80 m will be used for wave load generation. Associated current will be added to each of these load cases. Current velocity used 0.207 m/s at bottom and 0.900 m/s at surface; Linear stretch will be used and apparent wave period will be calculated; Automatic blocking factor will be used at elevation -5.0 m. Weight group selection INCWGT line for ANOD and WKWY will be added to each of these two wave cases for possible environmental loadings. In load combinations SUPX and SUPY using X000 to replace GRVX and Y090 to replace GRVY. Portion of modified Seastate input shall looks like following, LDOPT NF+Z 1.025 7.85 -79.50 79.50 MN NPNP K LCSEL SUPX SUPY … LOAD LOADCNDEAD INCWGT ANODWKWY DEAD DEAD -Z M LOADCNMASS INCWG
