To reduce the vertical displacement of the roadway floor system of the arch (shown in P6.32, part b) produced by the 48-kip load at joint 18, diagonal cables of 2 in. in diameter are added as shown in Figure P6.34. For this configuration, determine the vertical displacement of all the floor system joints. Compare the results of this analysis with part b of P6.32 by plotting to scale the vertical deflections of all joints along the roadway from joints 1 to 11. Properties of the diagonal cables are the same as those of the vertical cables.
