PROBLEM 5 A bracket carries an eccentric load of P = 200 kN at an eccentricity as shown in SD-004. Diameter of bolt is 20 mm Ø. Use LRFD. a. Compute the reaction of bolt A (in kN) b. Compute the reac

Answer 1

The reaction of bolt A can be computed using the LRFD method by calculating the moment caused by the eccentric load and the required resistance force of the bolt. The reaction of bolt B can be computed in a similar manner.

Step-by-step explanation:

To compute the reaction of bolt A, we need to consider the eccentric load and the diameter of the bolt. The eccentricity of the load is the distance between the line of action of the load and the centroid of the bracket. Let's assume the eccentricity is given as 'e'.

Using the LRFD method, we can calculate the reaction of bolt A as follows:

1. Calculate the moment caused by the eccentric load: M = P * e
2. Calculate the required resistance moment of bolt A: Mr = M / F
3. Calculate the required resistance force of bolt A: Fr = Mr / d
4. The reaction of bolt A is equal to the required resistance force: Ra = Fr

Similarly, to compute the reaction of bolt B, we follow the same steps using the appropriate eccentricity and diameter of the bolt.
