Determining medium concrete coupling beam in concrete shearing wall with openings

چکیده مقاله

Abstract

It is not secret for everyone that, in order to prevention buildings destruction during earthquake and reducing body and financial losses, we must be merge entered horizontal force on structures and also prevent excess displacement in structure. For reaching this vital case, different systems were invented and implemented as an axial load system. One of the most important systems which it use in buildings saliently, is shearing walls system. Population growth and high costs of urban infrastructures establishing , necessity of agriculture fields conservation cause to human select different methods for construct high buildings based on construction economical and safety concepts. Concrete frames for buildings more than 22 stories constitute significantly percent of buildings. Shearing wall is a resistant element of buildings which it design for bearing bending, axial and shearing forces exposed of earthquake vertical and horizontal loads. It cause to structure hardness significantly and it bear gravity loads after brittle and failure. It is main factor for structure safety degree increasing against collapsing
