Response spectrum generator according to Romanian standard

Procedure to input a new Romanian standard seismic spectrum

Expand branch Libraries of the main tree menu.
Expand sub-branch Loads.
Start function Seismic spectrum to open the Seismic Spectrum Manager.
Click button New.
In combo box Input type select option Romanian standard.
Review and, if required, adjust the spectrum parameters.
Click button Code parameter to review or modify the code-defined parameters of the spectrum.
Confirm the code parameters with OK.
Click OK to confirm the spectrum.
Close the Seismic Spectrum Manager.

Spectrum definition and code parameters

A response spectrum can be defined according to Romanian standard by selecting Romanian standard as Input type.

Max frequency & Step

The values of the spectrum are generated between a maximum period of 4 seconds (=0.25 Hz) and the input maximum frequency, using the input Step value.

Code parameters

This button opens the dialogue defining the code-dependent parameters.

Spectrum type

Direction of the spectrum; horizontal or vertical

County

County for the selection of the location; all the mapped parameters of the spectrum are pre-configured; to input a customized spectrum, select Other location in the list

City

City for the selection of the location; all the mapped parameters of the spectrum are pre-configured

Gamma - importance factor

Importance factor, defined by the user

Coeff. accel. ag

Nominal ground acceleration expressed as a multiple of the acceleration of gravity g

ag - nominal acceleration

Nominal ground acceleration; obtained from mapped values, unless Other location is selected

TB, TC, TD

Reference periods of the response spectrum; obtained from mapped values, unless Other location is selected

beta0

Coefficient for the constant acceleration portion of the spectrum

q - behaviour factor

Behaviour factor, defined by the user

Theoretical background

Horizontal design spectrum	Vertical Design spectrum

If Other location is selected, then a_g, T_B, T_C, T_D, β₀ are defined manually.

The importance factor γ_I and the behaviour factor q are defined by the user in all cases.
