(Published 1995, 70 pages)\u003c\/p\u003e\u003cp\u003eThis report addresses structural response modification factors (R factors), which are used to reduce the seismic forces associated with elastic response to obtain design forces. The report documents the basis for current R values, how R factors are used for seismic design in other countries, a rational means for decomposing R into key components, a framework (and methods) for evaluating the key components of R, and the research necessary to improve the reliability of engineered construction designed using R factors.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eClick \u003ca href=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0839\/4224\/4564\/files\/atc19-toc.pdf?v=1783550278\" target=\"_blank\"\u003ehere\u003c\/a\u003e to view the Title Page, Preface, and Contents.\u003c\/strong\u003e\u003c\/p\u003e","brand":"Applied Technology Council","offers":[{"title":"Default Title","offer_id":48162042249428,"sku":"ATC-19","price":30.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0839\/4224\/4564\/files\/ATC-19.jpg?v=1782184296","url":"https:\/\/store.atcouncil.org\/products\/structural-response-modification-factors","provider":"The ATC Store","version":"1.0","type":"link"}
