Seismic vulnerability of reinforced concrete (RC) buildings is strongly influenced by beam-column joints. Horizontal and vertical structural members converge in joints, as extremely delimited areas where the internal forces core reinforcing bars have elevated stress gradients. In order to fully understand seismic behavior RC related failures T- X-shaped joints (external corner internal-position...

Multi-level shaking table tests were performed on a 1:3 reduced scale two-story reinforced concrete (RC) intermediate moment resisting frame (IMRF) conforming to the requirements given in ACI-318-19. The exterior joints lacked shear reinforcement assess viability of ACI model recommended for determining design strength beam–column joint panel.

Seismic codes were developed to reduce the structural vulnerability and risk associated with earthquakes in earthquake-prone regions of world. The effectiveness code preventing damage is dependent on performance level defined construction technology employed. seismic fragility curves for two recent versions Iran are determined by using hybrid method. probability levels visualized these curves. ...

beam to column welded connection with radius cut on beam flange is known as rigid connection that provides acceptable ductility for special moment resisting frame (smrf). in order to decrease the cost of construction and to provide an easy-to-construct structure, the new method is available for reducing the beam section based on drilling on beam flange , known as drilled flange connection (dfc)...
