PS_cal_cpp: Response computation

In wltcwpf/RCTC: The Rotated Combination of Two-Component Ground Motions

Response computation

Description

Compute response acceleration, pseudo-spectral acceleration (PSA), and spectral displacement

Usage

PS_cal_cpp(data, period_t, damping, time_dt, type_return)

Arguments

data	An acceleration time series array (in g)
period_t	An array of oscillator periods
damping	Damping ratio, expressed as a decimal
time_dt	Time step, in sec
type_return	A dummy variable controlling output type, set to either 1 or 2. If 1 is selected, it returns a four-row matrix with actual spectral acceleration (in g) in the first row, PSA (in g) in the second row, PSV (cm/s) in the third row, and spectral displacement (cm) in the fourth row at each of the specified periods in period_t. If 2 is selected, it returns a matrix with response displacement (cm) (number of periods in period_t by data points)

Value

The response acceleration and PSA, or spectral velocity and spectral displacement. It depends on type_return.
