Template > Response Spectrum SNiP II-7-81* – Russia

Macro for generation of the elastic response spectrum according to SNiP II-7-81*/SP 14.13330.2011.

Using the Chapter 5,Paragraph 5.6 and Formulas (3) and (4) as well as Figure (2),Response Spectrum diagram was made according to Russian standard for Structures in Seismic Regions.

Setting	Description
Soil profile type	It is possible to switch between 2 diagrams in dependence of soil type. 2 separate diagrams were made for Soil types I and II and Soil type III.
Output variable	Name of the variable that describes the response spectrum. The default name will be set up as SNiPd. A two-digit alpha-numeric suffix (Variable postfix) can be added to that names (e.g. in case that more than one response spectrum is generated to not overwrite the existing ones). The variable (and the related variables, formulas and tables) is stored in Properties > Variables and can be used when defining the earthquake load (Schedule > Load Definition > Earthquake Load).

Description

Soil profile type

It is possible to switch between 2 diagrams in dependence of soil type.

2 separate diagrams were made for Soil types I and II and Soil type III.

Output variable

Name of the variable that describes the response spectrum.

The default name will be set up as SNiPd.

A two-digit alpha-numeric suffix (Variable postfix) can be added to that names (e.g. in case that more than one response spectrum is generated to not overwrite the existing ones).

The variable (and the related variables, formulas and tables) is stored in Properties > Variables and can be used when defining the earthquake load (Schedule > Load Definition > Earthquake Load).
