Seismic Upgrade of Beam-Column Joints with FRP Reinforcement
Many opportunities are becoming available for using composite materials to strengthen/upgrade existing reinforced concrete (RC) structures. This paper focuses on a new technique for the seismic upgrade of RC beam-column connections in gravity load-designed (GLD) frames by the application (combined or not) of FRP rods and laminates. The FRP rods provide flexural strengthening, whereas the lay-up...
متن کاملPlastic Hinge Integration Methods for Force-Based Beam–Column Elements
A new plastic hinge integration method overcomes the problems with nonobjective response caused by strain-softening behavior in force-based beam–column finite elements. The integration method uses the common concept of a plastic hinge length in a numerically consistent manner. The method, derived from the Gauss–Radau quadrature rule, integrates deformations over specified plastic hinge lengths ...
متن کاملSeismic Behavior of Steel Reinforced Concrete Beam-Columns and Frames
The ability to perform accurate nonlinear simulations is a key component in the assessment of the behavior of seismic force resisting systems. A three-dimensional distributed plasticity formulation for composite beam-columns suitable for nonlinear static and dynamic analyses of composite seismic force resisting systems has been developed. New uniaxial constitutive relations are developed for th...
متن کاملEffect Of Web Reinforcement On Ultimate Strength Of Reinforced Concrete Deep Beam
It is observed that, reinforced concrete beams failed due to flexure but in case of deep beam failure occur due to shear. Deep beams may be defined as the beam where shear span to depth ratio less than 2. A number of researchers already proposed various approach to predict the ultimate strength of deep beams. In this study a newer approach is developed to calculate the ultimate shear strength o...
متن کاملnon-linear seismic behavior of concrete beam - column connections
a parametrik investigation was conducted to study the non-linear behavior of precast and cast-in-place reinforced concrete beam-column connections subjected to tabas seismic forces (1979). the behavior of these types of connections in a four stories structure with respect to strength, ductility , stiffness, and bond deterioration at the joint core are presented and discussed. calculation result...
