Effect of Pounding on RC Buildings

  Lakshmi S,  Manju George

It is observed during past earthquakes that adjacent buildings get damaged due to pounding and sometimes it leads to collapse of the building. It is also observed that at the thermal expansion joint provided in the building, at common wall between adjacent buildings pounding takes place due to inadequate gap, building hit each other and may lead to damage and sometimes complete collapse of the building. This paper investigates the pounding effect on multi-storey RC building during earthquake using building models. A parametric study on buildings pounding response is carried out using finite element based software. The time history analysis of two adjacent symmetric and unsymmetric buildings with load transfer from node to node and from node to column is carried out. The result is compared using shear force, joint displacement, bending moment etc.
