Print or save all types of data generated in SGSw in various formats and open previously generated data. Extract and plot graphs of earthquake history records, seismic response spectrums and design response spectrums using the earthquake database built-in SGSw. Select all types of options for graphs. Select to view Toolbar and Status Bar. Zoom Out a zoomed in view. Convert between time domain and frequency domain views.

Acceleration Record Select Generate > Earthquake Record to display the Earthquake Record Generation dialog box shown below. Select an earthquake component in the Earthquake field. Enter the scales for the amplitude and time step then click . All the generated data are normalized accelerations in g (acceleration of gravity) and the initial time step is 0.02 sec. Data can also be generated by changing the time step and amplitude of the original data using the amplitude and time scales. When data other than the built-in earthquake history records are to be generated, click to open the data in [.dbs] (sgs dbase file) extension files generated by the user.

Note
Design Response Spectra Generate various design response spectra and plot them in graphs. The detailed menus are as follows: - UBC 88-94 Design Spectrum: Design response spectrum specified in UBC 88~94 Dynamic, Uniform Building Code - UBC 97 Design Spectrum: Design response spectrum specified in UBC 97 Dynamic, Uniform Building Code - ATC 3-06 Design Spectrum: Design response spectrum specified in the ATC 3-06 Provision, Applied Technology Council - Newmark & Hall Design Spectrum: Newmark & Hall Design response spectrum - KS-Code Design Spectrum: Design response spectrum specified in the Korean Architectural Structures Design Criteria (1986) - KS-Code 2000 Design: Design response spectrum specified in the Korean Architectural Structures Design Criteria - KS-Bridge Design Spectrum: Design response spectrum specified in the Seismic Design Criteria of the Korean Highway Bridges Specifications - IBC 2000 Design response spectrum - Eurocode-8, 1996 Design response spectrum - China (GB50011-2001) Design response spectrum - Japan (AIJ, 2000) Design response spectrum Select the detailed menu corresponding to the design response spectrum to be generated to display the following Design Response Spectrum Data Entry dialog box. Enter the data necessary to generate the spectrum and click to generate the data and plot the graph.

From the Main Menu select [Option] to display the following detailed menus : Each sub-menu becomes inactivated if it deems inapplicable for the current data type. X Scale Log: Display the X-axis of the graph in a Log scale. Y Scale Log: Display the Y-axis of the graph in a Log scale. X Grid: Display gridlines in the X-direction of the graph. Y Grid: Display gridlines in the Y-direction of the graph. Diagonal Grid: Display gridlines in the diagonal direction of the graph. Line Width: Adjust the thickness of graph lines. Convert between bold and thin lines. Unit: Change the units for the generated data. Edit Graph Title: Change the title for the graph.
