Draw the influence lines for BC, JC and JI in the following bridge truss. Note that traffic will move across the top chord of the truss. Evaluate the maximum tension and compression forces in member CH caused by the following load conditions:a. Uniform dead load D= 1.5 K/ftb. Uniform live load L= 2.1 K/ftc. Concentrated live load= 95 Kipsd. An impact load ratio= 25%
