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...

Abstract Bridge foundation scour is one of the major problems for bridges in Nepal. Kathmandu Valley, which main economic hub and capital Nepal lies a seismically active zone. In this study, bridge spanning over Bagmati River Valley studied as reference to assess seismic response typical affected by scouring. Modal analysis revealed becomes more flexible when depth 2 m considered. A series push...

The governing equations of motion for bridges with rocking piers unequal height and span lengths are derived accounting the effect end joint gaps abutment-backfill system. attenuation stems from impacts at interfaces, described through coefficient restitution, also (pounding) superstructure on abutment backwalls. This is first study to author’s knowledge that combines both energy-dissipation so...

Structural pounding between adjoining multistory buildings with different total heights and story levels has been repeatedly identified as a frequent cause of severe damage during seismic excitations. This phenomenon is very intense when upper floor slabs short hit the columns taller more flexible structures within their deformable length. On other hand, it well accepted that infill masonry pan...

The pounding tuned mass damper (PTMD) is a novel vibration control device that can be used for many different structures. The PTMD utilizes a viscoelastic delimiter to enhance its vibration control effectiveness and robustness though pounding between the tuned mass and the viscoelastic material. However, the viscoelastic material is subjected to repeated poundings during its service life, which...

During strong earthquake excitations, base-isolated buildings may collide, either with the surrounding moat wall or with adjacent buildings if the available clearance is exceeded. This undesirable possibility has been recently investigated by several researchers, adopting various types of force-based impact models. Evidently, an important issue that arises regarding such numerical studies is th...
