Design the lightest W16 tension member section of steel of Fy= 50 ksi, Fu= 65 ksi to support a tensile service dead load PD = 270 k and a tensile service load PL= 220 k. the member is to be 53 ft. long the member is to have two lines of bolts in each flange for 7/8-in bolts (there are three in a line 4 in on center). At the end you should make the necessary checks.

ACI Code

Explain how the positive and negative bending moment in the beam is accounted in the construction of the beam.

Q.3) USE ONLY GRAPHICAL METHOD: A consolidated-drained triaxial test was conducted on a normally consolidated clay with a chamber pressure, σ3 = 172 kN/m2 . The deviator stress at failure, (Δσd)f = 227 kN/m2 . Determine (12 points): a. The angle of friction, φ' b. The angle θ that the failure plane makes with the major principal plane c. The normal stress, σf', and the shear stress, τf, on the failure plane

The bottom reinforcement in a 200mm × 500mm concrete beam is found to have corroded during its service life. Scans indicate that the effective diameter of the steel has reduced from 16?? ?? to 15?? ??. Determine the % reduction in the tensile capacity of the beam. The yield strength of the steel reinforcement is 500??Pa.
