43. In this table note the following: Figure D-9: Table For Capacity Spectrum • Step identifies the step number in the pushover curve. • Teff is the effective period at the associated step. • βeff is the effective damping at the associated step. • Sd(C) and Sa(C) define a point on the ADRS capacity curve for the associated step. • Sd(D) and Sa(D) define a point on the single demand spectrum (variable damping) curve for the associated step. • Alpha is the factor used in converting the base shear to spectral acceleration at the associated step. • PF*φ is the factor used in converting the displacement to spectral displacement at the associated step. • To print this table, click on the File menu at the top of the table and select either Print Tables, to print to a printer, or Print Tables To File..., to print the table to a file. 44. Click the “X” in the upper right-hand corner of the table to close it. 45. Select the Base Shear vs Control Displacement option in the Plot Type area. SAP2000 Web Tutorial 1 120
46. From the File menu at the top of the Pushover Curve dialog box select Display Tables. A table similar to that shown in Figure D-10 appears. 47. In this table note the following: Figure D-10: Table For Pushover Curve • Step identifies the step number in the pushover curve. • Displacement and Base Shear define a point on the pushover curve for the associated step. B C • A-B, B-IO, IO-LS, LS-CP, CP-C, C-D, D-E, >E all identify the total number of hinges within each of these ranges on their associated forcedisplacement curves. Force IO LS CP D E • TOTAL is the total number of pushover hinges in the structure. A Displacement • To print this table, click on the File menu at the top of the table and select either Print Tables, to print to a printer, or Print Tables To File..., to print the table to a file. 48. You can also print graphic plots of the pushover curve and/or capacity spectrum curve as follows: SAP2000 Web Tutorial 1 121
