Problem 1 determine the design capacity of the unstiffened

Question

Problem 1: Determine the design capacity of the unstiffened plate girder web of Grade 300 steel shown in the below figure.

Problem 2: The angle shown is a tension member in a truss and has to sustain a factored load (N*) 220KN. The chords to which the angle connects are 12mm thick.

Determine the number of M24 Grade 4.6 bolts required. Each bolt is in single shear and the threads are in the shear plane. (Bolting category 4.6/S)

Problem 3: Determine the required size of fillet weld to join the plates show below: Use E48XX electrodes. Category SP welding is required.

Answer 1

For the mechanics problem illustrated below, apply the appropriate concepts and formula and provide solution to each part. Question 1: Find out the design capacity of the unstiffened plate girder web of Grade 300 steel described in the figure in the problem. Question 2: The angle illustrated is a tension member in a truss and consists of to sustain a factored load (N*) 220KN. The chords to which the angle joins are 12mm thick. Find out the number of M24 Grade 4.6 bolts requisite. Each bolt is in single shear and the threads are in the shear plane (that is, Bolting category 4.6/S) Question 3: Find out the required size of fillet weld to join the plates illustrated below: Make use of E48XX electrodes. Category SP welding is requisite.
