Trimmers provide the support necessary to transfer the load carried by the headers to the foundation. True O False

A beam cross-section is limited to the size shown. Determine the required area of reinforcement for service load moments Mp = 400 ft-kips and ML = 250 ft-kips. Check crack control requirements f = 4000 psi (normalweight) f, = 60,000 psi d' = 2.5" b= 12" A's d₁= 32"
