Probability Analysis of Crane Load and Load Combination Actions

Figure 2

Schematic diagram of two cranes acting in combination on a runway beam. Note: is the adjacent column spacing (the span of the crane beam); point and point are the crane beam bearing connections; point is the mid-span position of the beam; is the width of the crane; is the wheel distance of the crane; and expresses the load (vertical load or horizontal force) for each crane.
