STAT210prob2.36: Shear Strength of Steel Girder

Description

An article in the Journal of Strain Analysis (vol. 18 no. 2, 1983) compares several procedures for predicting the shear strength for steel plate girders. This data shows nine girders in the form of the ratio of predicted to observed load for two of these procedures, the Karlsruhe and Lehigh methods.

Usage

STAT210prob2.36

Format

A data frame with 9 observations (rows) and 3 variables (columns).

	Column name	Data type	Description	Values
[,1]	Karlsruhe	numeric	Ratio with the Karlsruhe method	(1.151 - 1.559)
[,2]	Lehigh	numeric	Ratio with the Lehigh method	(0.992 - 1.178)
[,3]	Difference	numeric	Difference between the methods	(0.125 - 0.507)
