4. Design a welded connection to resist the loading shown below (service load). A double angle tension member, 2 L5x5x5/16, is connected to a 3/8 inch thick gusset plate with fillet welding. Fy = 50 ksi for the angles and Fy = 36 ksi for the gusset plate. Compute the size and length of welding on the side of angles based on LRFD and indicate the information on the sketch. 1 = %" 2L5 x 5 x h6 D = 30 k L= 75 k

Using SMAW process, E70 electrodes and an A572 steel. Determine the length of the side fillet welds for the full capacity the 125x100x10mm angle tension member as shown below. Assume that the member is subjected to repeated stress variations making any connection eccentricity undesirable. Check the block shear strength of the member. Assume that the WT chord has sufficient strength to develop the weld strengths and the thickness of its web is 12mm. Use U = 0.87 for class use and LRFD Method only

Нome work 1. A plate( 100 mm) wide and (10 mm) thick is to be welded with another plate by means of double transverse welds at the ends. If the plates are subjected to a load of (70 kN ), find the size of weld for static as well as fatigue load. The permissible tensile stress should not exceed (70 MPa) [Ans. 83.2 mm; 118.5 mm]

An axially-loaded welded angular connection is shown SD-002 . The angular section 150 x 100 x 10 mm having an area of 2400 mm? is welded to a gusset plate having a thickness of 10 mm. All steel is A 36 (Fy = 248 MPa, Fu = 400 MPa) and E (70) electrodes (Fu = 484 MPa) is used. Using the shielded metal-arc welding process. Compute the value of "a" if T = 500 kN. (Please do not round-off to whole number the required thickness, use the exact (2 decimal) value.) 150 mm SD-002
