For the eccentric shear loading of the accompanying figure, 7/8 inch diameter A325 bolts are used in two vertical lines in a bearing-type (A325-X) connection. The loading is 10 kips dead load and 30 kips live load.
a) determine the adequacy of the design using basic principles of the elastic (vector) method;
b) Compute the service load capacity of the connection using ultimate stength analysis;
