Seismic analysis of plain masonry structure made of 1:2 reduced scale clay burnt bricks excited by shake table

Masonry building worldwide exhibits severe damage and collapse in strong earthquake events, which is mainly due to the combination of low tensile strength, large mass and insufficient connection between structural elements, is the main limitation for their structural implementation in residential building. The study of structural dynamics is commonly perceived to be a difficult exercise. This paper includes experimental testing of plain masonry structure. To study the basic issues related to vibration behavior, cracking pattern, failure mechanism and In-plane; out-plane behaviour in terms of displacement & lateral drift, an experimental testing of plain masonry structure without reinforcement is carried. The model is plain structure made of clay burnt bricks (1:2 reduced scales).The test is conducted on uniaxial shake table. The frequency of the motion of shake table is varied by changing the RPM of the electric motor.
