2.According to the design philosophy in the AASHTO Specifications, how does a heavy truck parked on a prestressed bridge girder effect the nominal shear resistance of the girder?
3.What is the main difference between the calculation of deflections for reinforced and prestressed concrete beams?
Traffic signals were installed at an intersection involving two one-way streets. Suppose 75% of the vehicles will decelerate when they see the amber light, whereas 20% will accelerate and 5% are "indecisive" and simply continue with the same speed..
