Pounding effectsin RC Frame structures

Abstract

Pounding between neighboring buildings is a common phenomenon which can be observed during strong
ground motions. It can damage the buildings and also can cause loss of life and property. It is an important phenomenon
and therefore, shall be considered in modeling of buildings for structural analysis. In this study, the pounding has been
considered in the modeling of two hypothetical case study buildings for seismic Zone 2B as per BCP-SP07 building code
of Pakistan. Etabs has been used for the said purpose. The buildings are analyzed using Non-linear modal time histories
as per BCP-SP07. Various analysis results have been compared. The analysis results show that pounding increase
displacement up to 2 times as compared to without pounding case. Pounding increase, the axial forces up to 230 times
and bending moment up to 3 time in the beams being collided. Similarly, the shear forces are also significantly increased
in case of pounding as compared to without pounding case
