Development of CSMM-based shell element for reinforced concrete structures

Finite Element Analysis of Bond for Reinforced Concrete Structures

A high-resolution finite element model is developed using the MSC.Marc software package to investigate local bond behavior and the modeling of this behavior. In the model, interaction between concrete and steel is treated geometrically as contact between two separate bodies. Concrete is modeled as a homogenous material. A multiple, fixed, smeared crack model is used to simulate response in tens...

Damage Detection of Reinforced Concrete Structures Based on Concrete-steel Interface Element

The interface between concrete and steel in reinforced concrete governs the interaction between the two types of materials under loading. When the interface is seriously damaged, such that a macro-crack is formed, de-bonding takes place or large slip occurs, and the load-transferring capacity of the interface will drop dramatically. In this study, a vibration-based method is presented to detect...

Considering the Soil Effects on Design Process of Performance-Based Plastic Design for Reinforced Concrete Structures

In this research, Performance-Based Plastic Design (PBPD) method has been modified according to the proposed method for considering Soil–Structure Interaction (SSI) effects. In the proposed modified method, based on the existing relationships and in order to maintain the simplicity of the PBPD design method, two important parameters have been modified in the PBPD design method. These two parame...

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 ...
