The most important property of a base-isolation system is to make the base more flexible than the elements of the superstructure, but it must still be stiff enough to resist typical pounding forces, wind loadings, and similar low-amplitude horizontal forces. However, the potential consequences of earthquake-induced poundings on seismically isolated buildings can be much more substantial, and, t...

The structural pounding caused by an earthquake may damage structures and lead to their collapse. This study is focused on the between two adjacent asymmetric with different dynamic properties resting surface of elastic half-space. An exploration relationship effects seismic analysis impact response torsional buildings under SSI has been presented. In this paper, authors have proposed a procedu...

With rapid population growth over the past 30 years and no significance seismic activity during this period, the unchecked development of the built environment in Bangladesh has been resulted in little resilience to earthquake. Identifying buildings due to this unchecked development that has high vulnerability is of critical importance both for reliable loss estimation as a result of an expecte...

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 ...

We present the results of a series of experiments at the Kumamoto Sanctuary in Japan, in which captive chimpanzees (Pan troglodytes) performed several nut cracking sessions using raw materials from Olduvai Gorge, Tanzania. We examined captive chimpanzee pounding tools using a combination of technological analysis, use-wear distribution, and micro-wear analysis. Our results show specific pattern...

Seismic pounding occurs as a result of lateral vibration and insufficient separation distance between two adjacent structures during earthquake excitation. This research aims to evaluate the stochastic behavior of adjacent structures with equal heights under earthquake-induced pounding. For this purpose, many stochastic analyses through comprehensive numerical simulations are carried out. About...

The methods for preventing earthquake-induced structural pounding between two adjacent buildings include ensuring a sufficient separation distance them or decreasing their relative displacement during seismic excitation. Some equations even specific values of such gap sizes have been introduced so as to avoid collisions. Increasing the stiffness buildings, using tuned mass dampers, applying liq...
