Title: RE: Cyclic loading and A490 bolts

Yes, A490 bolts can be used to resist cyclic shear loads.  However, they are required to be pretensioned.  See the AISC LRFD Specification (chapter J) and the RCSC "Specification for Structural Joints Using ASTM A325 and A490 Bolts".  These can both be found in the back of Vol. 1 of the LRFD Manual.
