in this paper, load and buckling mode of a smart column are presented. the theoretical model is a three-layer piezoelectric composite beam that behaves as an axial actuating mechanism. this actuator consists of an elastic core sandwiched between two piezoelectric active outer layers. the piezoelectric layers are polarized transversely, i.e., the polarization vector is parallel to the applied el...

Abstract Recent devastating earthquakes worldwide pointed out the importance of seismic detailing and their influence on observed damage subsequent repairability reinforced concrete buildings. Several studies post-earthquake observations remarked role beam–column joints (BCJs) global building response effectiveness transverse reinforcement in increasing joint shear strength ultimate deformation...

The principal objective for this work was to extend the field of application FEM space frame beam-column connections under static loading and with lateral displacements. A four-storey building modelled load condition. Horizontal vertical structural elements were designed according Eurocode 2. In order understand behavior external node made by column, two beam upper models using correct boundary...

This paper investigates the experimental and analytical behaviour of beam-column joints that are subjected to a combination torque, flexural direct shear forces, where different Carbon Fibre Polymer (CFRP) strengthening wraps have been applied only beam. These wrapping schemes previously determined by research community as an effective method enhancing torsional capacities simply supported rein...

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...

The objective of this study is to compare the performance for welded beam-column joints in aluminum structures using moment-rotation diagrams and evaluate influence welding on joint rigidity. A nonlinear numerical calculation beam–column performed finite element method. Material geometric nonlinearities were included model. connection was analyzed two cases: variants with without stiffener plat...
