Discussion on Masonry Structure Model Mechanical Property Test

Abstract

The problems in the mechanical test of masonry structure model were discussed in this paper, including the masonry material, similar relationship, shaking table test device, judgment of wall cracking and number of cycles in pseudo-static loading test. The conclusions are: (1) for the masonry material mechanical test, usually the size decreased the strength increased, but if the laying method and appropriate adjustments in the process of the test mixture ratio, the size effect can be greatly reduced; (2) In the dynamic test of the masonry structure, for the gravity distortion model, the common way is the external prestressing method, but in this method the tension force is not constant, which is differ from the actual situation; (3) The wall cracking can be judged when the main tension crack of the wall appeared; (4) The loading cycle in the pseudo-static test of masonry wall would be twice.
