Effect of Seismic Pounding on Adjacent Blocks of Unsymmetrical Buildings Considering Soil-Structure Interaction
During earthquake buildings which are closely spaced vibrate out of phase if there is insufficient distance between two adjacent building to accommodate maximum lateral displacement, they collide with each other this phenomenon is called as pounding. Pounding leads to verse damages to structure as the responses are drastically increased in terms of base shear, absolute acceleration, impact forc...
متن کاملEarthquake Pounding Effect on Adjacent Reinforced Concrete Buildings
During earthquakes, pounding of adjacent buildings occurs due to their different dynamic characteristics as well as insufficient separation distance between them. Although earthquake loading is commonly considered in structural design, pounding of adjacent buildings is not usually considered and usually causes highly unexpected damages and failures. Pounding effect was numerically investigated ...
متن کاملSeparation between Adjacent Nonlinear Structures for Prevention of Seismic Pounding
Four existing methods to calculate critical separation distances between adjacent nonlinear hysteretic structures are evaluated through Monte-Carlo simulations, for which seismic excitation is characterized as a nonstationary random process. All the methods use the well-known Double Difference Combination rule, but follow different approaches to calculate the correlation coefficient ρ. Results ...

متن کاملPassive and hybrid mitigation of potential near-fault inner pounding of a self-braking seismic isolator
A seismic isolated structure is usually a long-period structural system, which may encounter a lowfrequency resonance problem when subjected to a near-fault earthquake that usually has a long-period pulse-like waveform. This long-period wave component may result in an enlargement of the base displacement and a decrease of the isolation efficiency. To overcome this problem, a rolling-based seism...
