A numerical simulation on dynamic properties of friction-resistant dry-masonry structures, known as "Steel Reinforced Brick based on Distributed Unbond Prestress (SRB-DUP)" is carried out. SRB-DUP uses steel plates and bolts for bonding bricks by introducing prestress in bolts. The purpose of this arrangement is to construct a re-usable yet earthquake resistant structure. Micro-modeling technique, where constituent materials (brick, mortar, reinforcement etc.) are modeled as separate materials, is adopted for modeling of SRB-DUP structural elements. The numerical model is verified using results of previously conducted dynamic and static tests on SRB-DUP masonry wall elements. Then simulation models are built and analyzed for various dynamic loads. We have succeeded to reproduce basic characteristics of the experimental results.
