The ordinates of the moment influence line at midspan B of a 2-span continuous beam are provided at every one-tenth of the span in Figure P14.7. (a) Position the HS 20–44 truck load in Figure 8.25(a) to produce the maximum positive moment, (b) Position the HS 20–44 lane loads shown in Figure 8.25(b) to produce the maximum positive moment. Which loading is more critical?
