Vibration control in buildings under seismic excitation using optimized tuned mass dampers

Francisco da Silva Brandão, Letícia Fleck Fadel Miguel

Earthquakes can cause vibration problems in many types of structures, generating large displacements. The interstory drift is a design criterion very used in seismic analysis and the structural control is an alternative to reduce these…

Natural Frequency based delamination estimation in GFRP beams using RSM and ANN

T. G. Sreekanth

The importance of delamination detection can be understood from aircraft components like Vertical Stabilizer, which is subjected to heavy vibration during the flight movement and it may lead to delamination and finally even flight crash…

Seismic vulnerability analysis of reinforced concrete frame with infill wall considering in-plane and out-of-plane interactions

Dan Wang

The seismic performance of a building hinges on the seismic capacity and damage features of the reinforced concrete (RC) frame with masonry infill walls. To reasonably evaluate the seismic performance and seismic economic loss of masonry…
