1. 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

2. 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

3. Inelastic analysis of semi-rigid composite structures under fire conditions
This paper presents the application of a proposed numerical approach, denoted as SAAFE Program (System for Advanced Analysis for Fire Engineering), developed to provide an inelastic analysis of steel and composite (steel-concrete) 2D semi-rigid framed-structures under fire conditions. The proposed structural model allows an accurate description of the struct

4. As ligações semirrígidas na análise avançada com zona plástica de portais planos de aço
In this work, the development of the Plastic-Zones Advanced Analysis of plane steel portals is studied, now including the connections effect. Firstly, this analysis is defined as inelastic second-order which capture the plasticity spread by slice technique and includes the Main Aspects as geometric (out-of-straight and out-of-plumb) and physical imperfection

5. Análise experimental estática e dinâmica da rigidez de ligações viga-pilar de concreto pré-moldado / Static and dynamic experimental analysis of precast concrete beam-to-column connection stiffness
Em estruturas de concreto pré-moldado, as ligações usualmente apresentam comportamento semi-rígido, apesar desse tipo de vinculação não ser sempre considerado no projeto e análise das estruturas. Ensaios dinâmicos para a determinação da rigidez da ligação apresentam a vantagem de serem não-destrutivos e a possibilidade de serem utilizados na ve

6. Theoretical and experimental study of beam-to-column connection with pad of mortar and bolts for precast concrete structures / Estudo teórico-experimental de ligação viga-pilar com almofada de argamassa e chumbador para estruturas de concreto pré-moldado
As ligações com chumbador e almofada, sem continuidade estrutural, são comumente empregadas em obras de concreto pré-moldado como galpões, edifícios de poucos pavimentos e no topo de pilares. Na análise estrutural, este tipo de ligação é caracterizado como articulado. Este trabalho teve como objetivo fazer um estudo com este tipo de ligação levan

7. Sistema Computacional para Análise Avançada Estática e Dinâmica de Estruturas Metálicas
A new computational tool for the advanced static and dynamic analysis of steel framed structures based on the Finite Element Method has been developed and is presented herein. Understanding the static and dynamic behavior of a structure is essential for designing structures that are lighter and slenderer without affecting their safety and quality standards.

8. Evaluation of the equivalent slip modulus of nailed connections for application in linear analysis of plywood timber beams
The study of the stiffness of laterally loaded semi-rigid connections in plywood-timber beams is justified by the influence that the deformation of the connection has on the overall displacements of the structure. Semi-rigid connections are characterized by the occurrence of a slip between the connected pieces. The characterization of a connection is usually

9. Comportamento de vigas protendidas pré-moldadas com ligações semi-rígidas.
The behaviour of prestressed precast beams is directly affected by the rotational stiffness of the end connections. Although the prestressed beam presents a linear behaviour in service, the effective behaviour of the precast beam depends on the interaction of the beam with the behaviour of its connections. The majority of the experimental investigations on s

11. Desenvolvimento de programa livre para análise de pórticos tridimensionais considerando-se a não linearidade geométrica, fissuração do concreto e ligações semi-rígidas
Structural analysis of framed structures using discrete method, wherein, splitting them into elements with simplified considerations, can bring not satisfactory results or end up using very high safety coefficient to the structure. With the growth of computing and microcomputers it is feasible the resolution of structures considering all parts, therefore thr

12. Flexural strengthening and stiffness increasing of precast beam-to-column connections by NSM CFRP strips / Reforço e incremento da rigidez à flexão de ligações viga-pilar de estruturas de concreto pré-moldado com polímero reforçado com fibra de carbono (PRFC)
This work presents the development of a technique for flexural strengthening and stiffness increasing of precast beam-to-column connections by the embedding of FRP strips into grooves made on the concrete cover. According to this technique, the tension in the connection is transferred by the Near-Surface Mounted (NSM) FRP strips. To allow the transference of
