strength and stability

The bond behavior of reinforcing bars is an important determinant of strength and stability. The article “Experimental Study on the Bond Behavior of Reinforcing Bars Embedded in Concrete Subjected to Lateral Pressure” (J. of Materials in Civil Engr., 2012: 125–133) reported the results of one experiment in which the researchers applied varying levels of lateral pressure on 21 concrete cube specimens, each with an embedded 16-mm plain steel round bar, and measured the corresponding bond capacity. Due to differing concrete cube strengths (fcu, in MPa), the applied lateral pressure was equivalent to a fixed proportion of the specimen’s fcu (0, .1fcu, . . . , .6fcu). Also, since bond strength can be heavily influenced by the specimen’s fcu, bond capacity was expressed as the ratio of bond strength (MPa) to

a. Does a scatterplot of the data support the use of the simple linear regression model?

b. Calculate point estimates of the slope and intercept of the population regression line.

c. Calculate a point estimate of the true average bond capacity when lateral pressure is .45f cu.

d. Calculate a point estimate of the error standard deviation σ.
