چکیده
One of the methods to reduce damages caused by earthquakes is to concentrate damages in predetermined members. During an earthquake, these members minimize the damage caused to other members of the structure by absorbing a major part of the earthquake force. These members act like an electrical fuse that is blown under an unauthorized current of electricity and prevents damage to the wiring and electrical appliances used; Therefore, these members are called "structural fuse" and sometimes abbreviated as "fuse".EBFs are one of the most important resistant systems for bearing lateral loads. Researchers, paying attention to the simple replaceability approach, have introduced a shear fuse with joint connection in the connection area, which is named as a simple replaceable fuse. In this project, a series of numerical and laboratory researches are carried out in full scale, and this article refers to the comparison of design parameters.In this article, a brief explanation of Young's, Presley-Pauli's and energy methods is presented in each section, and then the design parameters are determined and compared. ETABS software was used for frame design and ABAQUS was used for numerical analysis. The comparison results show that the use of this fuse in EBFs has significantly improved the design parameters. Due to the simplicity of manufacturing and installing this fuse, using this method optimizes the design and saves the costs of construction and seismic improvement.کلیدواژه ها
