moment-resisting frames have extensive usage in earthquake-prone areas and high ability in energy dissipation.after the earthquake in northridge 1994,kobe 1995 fixed connections of steel structures have shown poor performance and generally they were caught brittle fracture of beam flange weld to the column.in order to remedy to avoid similar situations in future earthquakes,researchers introduc...

Buckling-Restrained Braced Frame system(BRBFs) are a new type of steel seismic-load-resisting system that has found use in several countries because of its efficiency and its promise of seismic performance far superior to that of conventional braced frames. The system is addressed in the 2005 edition of the AISC Seismic Provisions for Structural Steel Buildings, also a set of design provisions ...

well-known seismic design codes have offered an alternative equivalent static procedure for practical purposes instead of verifying design trials with complicated step-y-step dynamic analyses. such a pattern of base-shear distribution over the building height will enforce its special stiffness and strength distribution which is not necessarily best suited for seismic design. the present study, ...

Abstract. In the recent past, authors proposed a new steel device devoted to representing an innovative moment resisting connection for frame elements called LRPD (Limited Resistance Plastic Device). It is element characterized by symmetry with respect three orthogonal barycentric planes and constituted sequence of portions abrupt cross section changes, each one identifies suitably designed geo...

This article provides a behaviour analysis of moment resisting joints with curved endplates. is new type connection that can be used for joining steel beams to the circular hollow section (CHS) columns by means bolts. Some researchers apply Eurocode model without considering differences in calculation schemes and assumptions, such as using general an equivalent T-stub tension. Consequently, man...
