Based on the application of a beam-column joint with replaceable energy-dissipating elements and hinged proposed by author, seismic performance fully assembled steel frame this was investigated in paper. Through two projects traditional (TSF) an applying joints (ASFWREE) their numerical simulation calculation SAP2000, main structural design indicators such as natural vibration period, period ra...

the joints between segmental rings can withstand a certain amount of bending moment as well as axial and shear forces. generally, in the structural analysis of tunnel segmental lining, the joints can be modeled as elastic hinges or rotational springs, and their rigidity should be demonstrated in terms of the rigidity of the joints or their rotational stiffness. therefore, the bending moment act...

There is wide use of beam-column joint with gusset plate angle connection in engineering, however, the mechanical properties these joints are still lack complete theoretical and experimental research. This kind often simplified as an articulated or other types connections design. In this paper, study finite element analysis carried out to flexural behavior connection. The used analyze differenc...

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...

Due to the scarcity of rational models for predicting the strength of RC beam-column sandwich joints, a modified simplified softened strut-and-tie model suggests a more rational calculation method for the effective compressive strength and the height of the joint concrete based on the simplified softened strut-and-tie. The shear strength of existing tested 15 sandwich interior joints is calcula...

This study presents a novel energy-dissipating prefabricated joint for connecting beam to column in precast frame structure. The joints are characterized by replaceable steel hinge and tube confined core, providing advantages concrete reinforced frames, such as complete assembly, damage control, maintainability of the structure after an earthquake. hysteretic behavior proposed was studied throu...
