analytical detection of cracking in connections of steel moment resisting frames using simple damage indices is important since these cracks are not visible unless the connections are uncovered. in this paper, applicability of three cumulative damage indices for detection of cracking in a cover plate welded moment connection is investigated. the damage indices considered in this study are based...

The seismic performance of elliptic braced moment resisting frame (ELBRF) is assessed here and is found that the structural behavior is improved and is of free of architectural space. The demand for seismic performance of ELBRF is estimated through conventional pushover methods of 3, 5, 7, and 10-story ELBRF frames and they are compared with special moment resisting frames (SMRF) and X-Braced C...

In the last two decades, high-rise timber buildings have been built using glulam truss system, even with limited openings. Moment-resisting frames (MRTF) semi-rigid beam-to-column connections can be an architecture-friendly way to provide a load-carrying system vertical and horizontal loads for buildings. these structures, of adequate ductility are crucial ensure robustness energy dissipation. ...

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...

progressive collapse is a chain reaction of failures propagating throughout a portion of the structure disproportionate to the original local failure occurring when a sudden loss of a critical load‐bearing element initiates a structural element failure, eventually resulting in partial or full collapse of the structure. both general services administration (gsa) and united states department of d...

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...
