1. Beam-Column Joints Reinforcement Detailing Adequacy in Case of a Corner Column Loss-Numerical Analysis
Abstract This study investigates the behavior of reinforced concrete (RC) beam-column joints at the corner panel after a ground corner column loss scenario. The ductility of a frame is dependent on the ductility of its components, particularly its joints. Deficiency in joints performance can be related to an unexpected event. For example, the removal of a gr

2. Seismic Upgrading of Exterior Reinforced Concrete Frame with Small Column and Joint Area Using Externally Attached Steel Column
Abstract This paper presents cyclic load test of five exterior reinforced concrete frames. All the specimens represent a substandard single-span, low-rise reinforced concrete frame building which behaves a weak column-strong beam mechanism under a strong seismic loading. The first three exterior frames M1, M2 and M3 were designed for the joint shear critical

3. Reinforced Concrete Beam-Column Inverted Knee Joint Behaviour after Ground Corner Column Loss-Numerical Analysis
Abstract Beam-column joints are critical component in the load path of reinforced concrete (RC) frames, due to their role in transferring loads among different RC frame components. The loss of a ground corner column in a RC frame turns an exterior joint into an inverted knee joint and recent code provisions for exterior joints are not sufficient to knee join

4. 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

5. Finite Element Analysis of Reinforced Concrete Beam-Column Connections with Governing Joint Shear Failure Mode
Abstract Reinforced concrete (RC) beam-column connections especially those without transverse reinforcement in joint region can exhibit brittle behavior when intensive damage is concentrated in the joint region during an earthquake event. Brittle behavior in the joint region can compromise the ductile design philosophy and the expected overall performance of

6. 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

7. Análise Paramétrica de Ligações com Placa de Extremidade em Estruturas de Aço Submetidas a Momento Fletor e Força Axial / Parametrical Analysis of Structural Steel Endplate Joints Subjected to Bending Moment and Axial Force.
Traditionally, the steel portal frame design assumes that beam-to-column joints are rigidor pinned. Rigid joints, where no relative rotations occur between the connected members, transfer not only substantial bending moments, but also shear and axial forces. On the other extreme, pinned joints, are characterised by almost free rotation movement between the c

8. Análise teórica e experimental de ligações viga mista-pilar de extremidade com cantoneiras de assento e alma / Theoretical and experimental analysis of single-sided beam-to-column composite joints with bottom and web angle connections
Este trabalho apresenta um estudo numérico e experimental do comportamento estrutural das ligações viga mista-pilar com cantoneiras de assento e alma. No estudo teórico foi desenvolvido, com base nos EUROCODES 3 e 4, um procedimento para avaliação do comportamento das ligações mistas com cantoneiras de alma e assento e com chapa de topo.

9. Estudo teórico-experimental do comportamento de nós de pórtico de concreto armado submetidos a ações cíclicas / Theoretical and experimental study of reinforced concrete frame joints behavior under cyclic load
The present thesis studies the behavior of frame joints in reinforced concrete beam-column joints subjected to cyclic loads. The thesis is divided into two parts: an experimental study and a theoretical-based study. The experimental study is based on laboratory tests on five physical models of beam-column joints. The results of this experimental study permit

10. Composite beam-column connection Theoretical and experimental analysis / Ligações mistas viga-pilar - análise teórica e experimental
A composite joint is a joint between a composite beam and a steel or composite column in which reinforced concrete slab is take into account. The moment-rotation relationship of composite joints depends on a significant number of parameters besides the type and configuration of the steel connection, as for example: the amount of steel reinforcement of the sl
