ASCE 7-22 site class of a shear-wave velocity

Classifies \(V_{S30}\) by the intervals of ASCE/SEI 7-22 Table 20.2-1: A at or above 1500 m/s, B from 910, BC from 640, C from 440, CD from 300, D from 210, DE from 150 and E below 150 m/s. The lower bound of each interval belongs to it. Class F requires site-specific criteria and is not assigned from a velocity.

Usage

classifySite(VS30)

Arguments

VS30

Finite non-negative velocities in m/s.

Value

A character vector of class identifiers aligned with VS30.

Examples

classifySite(c(120, 150, 790, 910, 3000))
