ENGINEERING PROJECTEARTHQUAKE VIBRATION CONTROL USING MODIFIED FRAME SHEAR WALL
SAFETYABSTRACTEarthquake is a serious and extreme disaster, which makes even larger andstronger buildings and infrastructure as vulnerable. The eventual result would bethe rehabilitation of these buildings and infrastructure, which are vulnerable innature. As the technology has been progressing, there are various technologiesdeveloped to improve the strength of the buildings and infrastructure, inearthquake prone regions. The present study gives insight of the new technologyand technique to strengthen the infrastructures and structures, with exterior shearwalls. The mission of the new technology is to protect the lives of the people andincrease the monetary losses.

SAFETYEARTHQUAKE VIBRATION CONTROL USING MODIFIED FRAME SHEAR WALLINTRODUCTIONThe earthquakes occurred in the past have either completely collapsed thebuildings or left many of them and experience various kinds of damages, structuresmade by the reinforced concrete. There have been various kinds of investigationscarried out, on the strength of the structures and buildings, against the capability towithstand to the normal to severe earthquake. Some of the structural deficienciesdiscovered with the reinforced concrete made buildings are poor quality concrete,weak columns, splice lengths that are inadequate, incomplete considerations of thedesign and short column behaviour. Eventually, as attempts to minimize thestructural deficiencies, various building codes are introduced and developed.Lateral stiffness, required ductility and strength are lower compared to the ones,imposed by the modern codes of buildings developed. Since these structurespossess low ductility, these structures are more prone to the demand of the largedisplacement, because of the deficiencies in the lateral strength and stiffness.
