EXPERIMENTAL STUDY ON STRUCYURAL PERFORMANCE OF HISTORIC BRICK MASONRY BUILDINGS
The tests of bending out of plane in size of original were conducted, in order to confirm the basic performance of masonry in this study.In order to confirm the structural characteristic of the brick walls was bended out of plane, the bending tests in size of original were conducted. The test pieces were designed based on the wall 2 bricks thick by English bond. Two types of the methods of stuffing with the joint mortar were made. One was stuffed the vertical joints with the joint mortar completely in order to identify the masonry structural system, the other was not stuffed completely because the nomal brick walls were not constructed completely. In addition, the tests of the brick walls strengthened were conducted. The strengthening was infusing the polymer cement mortar into the void spaces in the joint mortar (slurry).From the results of the tests, the ultimate bending moments were 9.9 to 12.7 kN?m. The ultimate bending moments almost were not differed between all the test pieces.In addition, the tension, compression, and shear tests of masonry elements were conducted in order to know the structural characteristics of the masonry structure. The shear tests were conducted with the compressive stresses that were loaded at right angle to the shear direction. From the results of the shear tests, shear strength and shear stiffness increase in proportion to the compressive stress.
