Repair and rehabilitation of existing damaged concrete structures have emerged as one of
the most important construction activities globally. Money used on repairing damaged …

This paper presents a modified concrete damaged plasticity model (CDPM) based on
ABAQUS, in order to accurately simulate the mechanical responses of steel-polypropylene …

Finite element (FE) modeling of confined concrete columns is a challenging task because it
requires accurate definition of the concrete material model to represent the volumetric …

Steel is a cheaper and more environmentally friendly alternative to externally confine
concrete compared to the commonly known fiber-reinforced polymer (FRP). Numerous …

Although concrete-filled steel tube (CFST) columns have been widely accepted in
applications, they suffer deterioration due to various reasons. On the other hand, the …

Although fiber reinforced polymer (FRP) confined concrete columns have been extensively
investigated, a satisfactory stress–strain model for the columns under eccentric loading has …

The confinement mechanism of concrete fully confined with fiber-reinforced polymer (FRP)
jacket (FRP jacketed concrete) is different from that of concrete partially confined with FRP …

A new and general stress-strain model for concrete confined by steel or fiber reinforced
polymer (FRP) is developed in this work. One additional variable and one constant are …

In this study, a deep learning based nanoindentation method is proposed to reduce the
complexities in evaluating mechanical properties of polymers. To uniquely identify the …

The damage evolution of concrete under multiple stress states is complicated because the
triaxial stress on the heterogeneous concrete affects mesoscale interactions between …
