<p>Brick buildings are the oldest constructional systems that have been prevalently constructed during the time. As appropriate knowledge about performance of these constructions is very important in optimizing, improving and developing them against inserted loads, we investigated cutting manner of brick beams as a specific element in brick buildings. The samples were under steady state loading at the middle of opening. Both beams were claps at both ends. Samples were studied in two conditions of reinforced armatures (in lengths) and without reinforced armatures. The results revealed about 7 times increase in loading capacity and about 6 time increase in maximum place change of the beam. It was resulted that cracking start and development was same in both samples but depend upon value of inserted loads.</p> <p>Firstly, experiments were performed on constructional materials in accordance with ASTM standards in order to determine type of mixtures and pressure strength of mortar on brick units.</p>
