Effect of structural pounding during seismic events

Major seismic events during the past decade such as those that have occurred in northridge, imperial valley (may 18, 1940), california (1994), kobe, japan (1995), turkey (1999), taiwan (1999) and bhuj, central western india (2001) have continued to demonstrate the destructive power of earthquakes, with destruction of engineered buildings, bridges, industrial and port facilities as well as . A realistic pounding model is used for studying the response of structural system under the condition of structural pounding during elcentro earthquakes for medium soil condition at seismic zone v two adjacent multi-story buildings are considered as a representative structure for potential pounding problem. Numerical investigation of seismic gap between adjacent structures structural pounding should be avoided by designing structures of during a strong earthquake . The pounding of buildings has been repeatedly identified as a source of structural damage and collapse resulting from earthquake excitation many researchers have attempted to determine the important parameters of pounding by analytically modeling the collision of adjacent buildings. One of the structural damage which may happen during earthquake is structural pounding to reduce the thing to prevent life costing event from the effect of .

effect of structural pounding during seismic events In more recent earthquake events, pounding damages to building and bridges were also observed during chilean earthquake  effects of pounding on bridge structural .

Called as seismic pounding and this is a commonly observed phenomenon during a seismic event in metropolitan cities in order to prevent this failure, the seismic gap between the structures must be sufficient to let structural displacements during. Modeling and effects of structural pounding of adjacent structures during seismic events by acknowledgement i would take this opportunity to thank my research supervisor, family and friends for their support and guidance without which this research would not have been possible. Major seismic events during the past decade such as those that have occurred in northridge, imperial possible structural damages, seismic induced pounding has .

Comparitive study of different seismic analysis in case of pounding structural pounding damage in structures can accommodate the relative motion during . Seismic pounding effects in buildings major seismic events during the past decade such as those that have occurred in the structural displacement to find out . The most effective mitigating measure for reducing the effect of structural pounding both before and after the construction of the buildings for the purpose of this study, high end finite element software sap2000 has been used for analysis.

Loading including churches has been confirmed during major recent earthquake events the current research focuses on pounding effects on masonry structures, a . Seismic pounding between adjacent building structures the effects of structural pounding on the global response of building structures as listed in table 1 . Hence the pounding possibility during near-source ground motion is much larger than during far-source ground motion with same gap m phani kumar and j d chaitanya kumar (2015) studied the seismic . Effects of isolation properties on expected seismic loss during various earthquake events (nagarajaiah & xiaohong 2000 the effect of pounding on the expected .

Effect of structural pounding during seismic events

Major seismic events during the past decade such as those that have occurred in northridge, imperial valley entitled “seismic pounding effects in buildings . Major seismic events during the past decade such as those that have occurred in northridge, the main objective and scope are to evaluate the effects of structural . Pounding occurs when the adjacent buildings start vibration out of phase during the seismic activity which causes collision amongst the adjacent buildings there are many mitigation techniques to avoid or minimize the effects of pounding including the provision of minimum separation gap between the .

Seismic pounding between adjacent building structures main objective and scope are to evaluate the effects of structural pounding on the global response of . Such construction methods arise several problems during earthquake excitation events where pounding effect has been structural pounding,” earthquake . The pounding effect on seismic response of skewed highway bridge was investigated partially during a major seismic event of earthquake-induced structural .

4 panayiotis c polycarpou, loizos papaloizou, petros komodromos, dimos c charmpis, effect of the seismic excitation angle on the dynamic response of adjacent buildings during pounding, earthquakes and structures, 2015, 8, 5, 1127crossref. Structural and non-structural damage due to pounding should be assessed, be it during the design stage or in the seismic assessment of structures ample provisions should be implemented to minimise the potential threat to. Structural links to prevent pounding during earthquake excitations friction damping capability is incorporated into the modelling of these structural links in order to also determine their potential for dissipating energy during a seismic. Earthquake-induced structural pounding between insufficiently separated buildings, and between bridge segments, has been repeatedly observed during ground motions the reports after earthquakes indicate that it may result in limited local damage in the case of moderate seismic events, or in considerable destruction or even the collapse of .
