Building pounding occurs between two adjacent buildings with small gap or without sufficient separation distance. It leads to damage buildings during earthquake due to impact. Many researchers have investigated building pounding based on impact force reduction and energy dissipation increase, when two buildings collide with each other. In numerical investigations, using specific link element, i...

Pounding research has been gaining momentum in the last decades with large earthquakes hitting cities insufficiently separated buildings. Even if no major structural damage may be observed case of slab–slab pounding, acceleration pulses influence response equipment and cause disruption their functionality. In this work, two different models are set up for reproducing shake table tests concernin...

Talisadya churna was prepared by pounding the individual ingredients in mortar and pestle and mixie. The Curna prepared by pounding the ingredients in mortar and pestle showed higher exhaustive extraction in hexane and solubility in alcohol. The Curna prepared by grinding the ingredients in mixie showed less acid insoluble content, high volatile matter, water soluble matter, and exhaustive extr...

Transverse steel damper (TSD) is a promising passive control device used for seismic isolation and has been validated to feasibly balance the girder transverse displacement inertial force in cable-stayed bridges. However, TSD system, pounding could occur at locations of tower legs when gap size insufficient accommodate girder-support relative under major earthquakes. can significantly affect dy...

of bridges are typically based on simplified analyses or empirical data from recent earthquakes. Since earthquake damage data are very scarce in the central and southeastern United States (CSUS), using analytical methods is the only feasible approach to obtain fragility curves. In 1990, bridges in the CSUS began incorporating seismic details. Some of the changes included the component design fo...
