Hello I am going to solve a design example manually. In last class we have discussedabout the steps followed for design of tension also computer algorithm has been shown
Example:A tension member 3 m long carries a factored tensile load of 200 kN. Design a suitablesingle angle unequal section when connection is made with (i) 20 mm diameter bolts ofgrade 4.6 and (ii) fillet weld. Assume longer leg to be connected with plate.

Solution (Connected with fillet weld):(a) Strength due to yielding of gross section
That means the section which we have considered that is 75 × 50× 10 in case of boltconnection as well as in case of weld connection it is safe, ok so this is how we can design asection under tensile load. Now this is not the end of the design because in case of weldconnection, we have to calculate the weld length and we have to distribute the weld lengthproperly. We know that this section is ok but what should be the weld distribution, whatshould be the weld length, we have to find out.Weld distribution:
So, this is how we can design a member due to axial tensile force and when we are going todesign, at the end we have to draw a diagram showing the distribution of the bolt ordistribution of the weld length. The total length of the gusset plate, what we are usingaccording to the required pitch and edge distance should be shown in terms of diagram so thatit will be easier to understand by the site engineer, ok. So, with this I like to conclude todayslecture thank you.
