A steel bar is attached to a wood support beam with four 22 mm diameter lag screws, as shown in the figure. The steel bar is 69-mm-wide by 8-mm-thick. For the steel bar, the yield strength is 235 MPa and the ultimate bearing strength is 350 MPa. The ultimate shear strength of the lag screws is 155 MPa. Factors of safety of 1.70 with respect to yield strength and 3.0 with respect to bearing strength are required for the bar. A factor of safety of 2.9 with respect to the ultimate shear strength is required for the lag screws. Determine the allowable load P that can be supported by this connection. (Note: Consider only the gross cross-sectional area of the bar-not the net area.) Support beam Answer: Pallow= 0000 P Steel bar KN
A steel bar is attached to a wood support beam with four 21 mm diameter lag screws, as shown in the figure. The steel bar is 66-mm-wide by 9-mm-thick. The yield strength of the steel is 265 MPa and the ultimate bearing strength is 345 MPa. For the lag screws, the ultimate shear strength is 160 MPa. If a factor of safety of 1.85 with respect to yield strength, 3.5 with respect to bearing strength, and 2.8 with respect to shear strength is required, determine the allowable load P that can be supported by this connection. For the yield strength criterion, consider the constant cross-section part of the steel bar.

Problem Solving: A rectangular beam has dimensions of 250 mm by 625 mm with an effective depth (distance from extreme fiber in tension to the centroid of the reinforcing bars) of 575 mm and is reinforced with three 25 mmp. The concrete cylinder strength f.' = 27.6 MPa and the tensile strength in bending (modulus of rupture) is 3.28 MPa. The yield point of the steel is 414.7 MPa.
