Ductility demands for MRFs and LL-EBFs for different earthquake types

摘要

The eccentrically braced frames with long links,LL-EBFs, is used in practice to safety the architectural demands to obtain free spaces in facades and to reduce lateral displacements.The paper shows that this solution must be used with the precaution,because,in some cases,the braced frames may behave badly than the unbraced frames.
