2. Experimental and numerical study of I-shape slit dampers in connections
Abstract This paper proposes a new beam to column connection which has slit dampers to increase ductility and moment capacity of structures. After Northridge and Kobe earthquakes, many researchers have tried to achieve more ductile connections. Ductility of connections causes to dissipate more energy before failure of connections. Also, some researchers have

3. Optimal design of beam-column connections of plane steel frames using the component method
Abstract This paper presents a methodology for optimization of beam-column connections of plane steel frames. The objective is to obtain beam- column connections mechanically more efficient and with minimum cost by determination of the optimal dimensions for the components of the connection; satisfying mechanical constraints associated with the bending momen

4. Numerical simulation of bolted connections
Abstract This article presents the modeling of a complete bolted connection based on a model with one bolt connecting two or three plates. Initially, the behavior of this model with one bolt is analyzed by comparing it with existing bibliography for 3 different types of applied load: tension, shear and a combination of these two. This model includes all nece

5. On the Nonlinear Transient Analysis of Planar Steel Frames with Semi-Rigid Connections: From Fundamentals to Algorithms and Numerical Studies
Abstract This paper presents the fundamentals for prediction of a more realistic behavior of planar steel frames with semi-rigid connections under dynamic loading. The majority of the research in this area concentrates on the nonlinear static analysis of frames with semi-rigid connections. Indeed, few studies have contributed to the nonlinear dynamic and vi

6. Classification System for Semi-Rigid Beam-to-Column Connections
Abstract The current study attempts to recognise an adequate classification for a semi-rigid beam-to-column connection by investigating strength, stiffness and ductility. For this purpose, an experimental test was carried out to investigate the moment-rotation (M-θ) features of flush end-plate (FEP) connections including variable parameters like size and nu

7. Behavior of Damaged Exterior RC Beam-Column Joints Strengthened by CFRP Composites
Abstract This paper presents an experimental investigation on the behavior of retrofitted beam-column joints subjected to reversed cyclic loading. The experimental program comprises 8 external beam-column joint connection subassemblages tested in 2 phases; one was the damaging phase and second was the repairing phase. The Beam-column joints were designed onl

8. Seismic performance of ductility classes medium RC beam-column connections with continuous rectangular spiral transverse reinforcements
The seismic performance of RC columns can considerably be improved through the use of continuous spiral reinforcement in terms of ductility and energy dissipation capacity. Since the beam-column connections were subjected to brittle failure after earthquakes, the simultaneous application of this method in both beams and columns could greatly improve the seis

9. Severe Loading Assessment of Modern and New Proposed Beam to Column Connections
AbstractThe performance of two different steel beam to column connections known as SidePlateTM and a new proposed connection by seismic loading and progressive collapse were investigated in this research. Seismic performance evaluated included consideration of interstory drift angles and flexural strengths based on 2010 AISC Seismic Provisions while investig

10. Estudo experimental de uma ligação viga-pilar em concreto pré-moldado utilizando perfis metálicos e solda / Experimental study of a precast concrete beam-column connection using welded steel shapes
Nesta pesquisa estudou-se o comportamento de uma ligação viga-pilar em concreto pré-moldado utilizando perfis metálicos embutidos nos elementos estruturais. O modelo da ligação estudada permite a transmissão de momentos fletores positivo e negativo. Para a continuidade de momento fletor negativo, utilizam-se um consolo metálico com seção \"U\" embu
