Stochastic discontinuum analysis of unreinforced

The unreinforced masonry walls are replicated via the system of deformable rectangular blocks interacting along their boundaries. Local failure modes of masonry (cracking, sliding, and crushing) are taken into consideration at the joints, in which the contact stresses are calculated and updated based on the relative displacement among the adjacent blocks and contact constitutive models, respectively.

Structural Response of Unreinforced Masonry Walls

2016-3-1  Most of the research performed on URM (unreinforced masonry) walls in the area of seismic behavior is based on experimental or numerical analyses [1-6]. In the field of experimental seismic research, different approaches to tests have been used for URM structures, that is, monotonic tests or quasi-static cyclic tests, dynamic tests on vibration table, and pseudo-dynamic tests. Dynamic tests can simulate seismic action with more accuracy, although the quasi-static cyclic tests make it possible to obtain more accurate measurements of forces and displacements, and the recording of damage evolution becomes simpler. Masonry walls are normally tested in laboratory under constant vertical load, varying the horizontal load. The typical configuration for quasi-static tests was suggested in such a way that the masonry panel is fixed in its bottom part and left loose in its upper part. This testing device, together with cyclic load, provides vital information (failure mode and damage evolution, form of hysteresis cycle, and dissipation of energy) for the evaluation of the seismic response of masonry walls.
