Seismic Performance of Inter-linked Block Masonry System with Viscoelastic Link Elements
Research Scholar - Amit Goyal
Supervisor - Prof. Pankaj AgarwalA new construction technique for earthquake resistant housing is being developed in the Department of Earthquake Engineering, IIT Roorkee. This is based on interlocking of pre-cast slotted concrete blocks with the help of energy dissipation links. These links are prepared by recycling pieces of rubber tyres laminated by very thin steel plates. These links not only restrict the movement of each concrete block is in all possible directions but also dissipate the energy through yielding under extreme earthquake loading conditions. The seismic performance of this interlocked block masonry system with energy dissipator links has been verified under simulated strong earthquake conditions of seismic zone V (the most severe zone) as per IS Code on the shake table testing facility. The tested system withstood this severe shaking without any distress and was found to be in a state fit for immediate occupation even after the test.
