After Northridge (1994) and Kobe (1995) earthquakes, several studies have been conducted to improve the seismic performance of steel structures. In this investigation, new steel moment-resisting connections (FSFN) developed by the authors, were studied by the non-linear numerical analysis. These connections were single-sided beam-to-column assemblies that are representative of exterior beam-to-...
The column-tree constructional schemes allows for a reliable and convenient erection of moment resisting steel frames. Strengthening of column-tree connection with a haunch part can significantly improve seismic behavior of whole system. In the current study behavior of column-tree connections with haunched beams and end plate splices have been investigated. Special attention was paid for evalu...
The worldwide use of precast concrete frames leads to an increase in the need for the investigation of efficient precast connections, particularly in the seismic regions. The current paper provides a numerical and experimental study on a dry precast connection. Experiments were conducted to validate the finite element method in the laboratory of the University of Science and Culture. To verify ...
Glue joints are more useful in Aerospace so in this article we presented new method for glue joint. In this method the maximum stresses that occurs at the edges of the bottom glue joint and cause ultimate failure in this type of connection is Decrease and increase the glue joint strength. In this method glue in the area overlapping the discrete and separate column considered Also, the connectio...
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...
Steel extended end plate bolted connections are recommended to be widely utilized in special moment-resisting frame subjected to monotonic loading. Improper design of steel beam to column connection can lead to the collapse and fatality of structures. Therefore comprehensive research studies of beam to column connection design should be carried out. Also the performance and effect of corrugated...
