Highly Deformable Energy-Dissipating Reinforced Concrete Elements in Seismic Design of Reinforced Concrete Structures

Seismic Response of Reinforced Concrete Columns

There are a large number of reinforced concrete buildings in seismically active areas of the world that are not built in accordance with modern seismic design provisions such as those published by American Concrete Institution ([ACI] Committee 318, 2008). In the United States and other parts of the developed world, these buildings were constructed between 1930s to mid 1970s according to the bui...

Yield curvature for seismic design of circular reinforced concrete columns

Adaptive Finite Elements for Reinforced Concrete Framed Structures

Abstract. This work focuses on the modelling of nonlinear response of reinforced concrete structures by means of the finite element method. A new technique which employs a variable mesh in order to reduce the computational cost of classical approaches is presented. For some piecewise linear constitutive models which are widely employed for the modelling of reinforced concrete, some properties o...

Effective Rigidity of Reinforced Concrete Elements in Seismic Analysis and Design

Seismic analysis and design of reinforced concrete structures are performed based on linear response, however it is universally accepted that under severe earthquakes inelastic response and cracking is accepted. Therefore element properties should reflect this condition and inertias of beams and columns should be reduced accordingly. Several procedures are suggested to considered effective rigi...

Exploration of Set-based Design for Reinforced Concrete Structures

To explore the feasibility of improving the delivery process of reinforced concrete, we focus in this paper on reinforcing bars (rebar) used in cast-in-place (CIP) concrete. Specifically, we describe the methodology for set-based design of rebar that we are pursuing in an ongoing research effort. Set-based design makes it possible to maintain feasible solutions for longer in the design process ...
