In addition to distributed dead load, the continuous beam shown below is subjected to uniformly distributed

live load. Assuming that the load combination of 1.2D + 1.6L governs, determine and show by figures the

live load distribution patterns used to obtain the following required strength as design basis:

(1) factored negative moment Mu at support B

(2) factored negative moment Mu at support D

(3) factored positive moment Mu at the mid-span of AB

(4) factored positive moment Mu at the mid-span of BC

(5) factored shear Vu at the immediately left side of section D

(6) factored shear Vu at the immediately right side of section D
