Question

Consider the truss with loading as shown below. This is an older truss that was recently inspected. It is to be evaluated based on the loads shown. Member CG, as constructed, had a cross-sectional area of 2.5 im2. The inspectors noticed places where corrosion has eaten into the material and reduced the effective amount of ateel available to carry structural loads. They estimate that effective cross sectional area in some locations is now 2 in2. The maximum tension stress permitted in the material is 21.6 ksi. Determine if the truss is still suitable for the load indicated. If not, determine what maximum loads could be supported while still satisfying the stress limit on the member CG (maintain the same 3-4-3 ratio between the three locations). Further, suppose3 member CG fails, Would the truss remain standing or fail entirely? Why? (Graphic source: Hibber, 2009)
