Masonry modelling (interaction)

Hi, is there anyone has the experience in modelling and solving masonry structural system ? currently im facing the issue in inputting the data of interaction between the blocks of masonry. i'm trying to model 3 storey masonry (material : Concrete Masonry Unit (CMU) ) building in ABAQUS program by implementing 'macro-modelling' technique, where the block size is 200x400mm including 10mm thickness of mortar joint. 

 1. is there any specific properties (or mortar properties) need to be lookup regarding on the interaction between the masonry blocks?2. is there any tutorial available regarding on this particular task ?
