Abstract

In the present work, a simplified hydro-thermal model for pore pressure calculation in concrete exposed to high temperatures is presented. The model is based on heat and mass transfer analysis in multi-phase porous media. The model has been structured in such a way that it is possible, [...]

Abstract

The effect of waterproof membrane and steel reinforcement protection on the concrete bridge deck is modeled. The attention is paid to the durability prediction related to steel reinforcement corrosion initiation based on the chloride penetration. Thus 2-D finite element chloride [...]

Abstract

Louis Kahn is often credited with having in his National Assembly in Dhaka (1962–1983) introduced modern architecture to Bangladesh. In fact at least as technologically advanced construction as any he employed was already in use there. Nor was he the first to use a sophisticated [...]

Abstract

A numerical model that accounts for the hydration and aging phenomena during the early ages of concrete curing is presented in a format suitable for a finite element implementation. Assuming [...]

Abstract

Aiming for the modeling of localized failure in quasi-brittle solids, this paper addresses a thermodynamically consistent plastic-damage framework and the corresponding strain localization [...]

Abstract

This paper presents the 2D and 3D numerical analysis of pullout tests on steel anchorages in concrete blocks using standard and mixed finite elements. A novel (stabilized) mixed formulation [...]

Abstract

The asymmetric tensile/compressive material behavior and microcracks closure-reopening (MCR) effects exhibited by quasi-brittle solids [...]

Abstract

The paper presents a systematically numerical procedure based on the finite-element method for three-dimensional analysis of segmentally constructed prestressed concrete bridges using hexahedral [...]

Abstract

The paper describes a finite element damage model for non linear analysis of concrete or reinforced structures. It is show how can be effectively used to predict local and global damage up to structural failure. Examples of applications of the model to the analysis of different [...]

Abstract

As a program increases its size and complexity, it can rapidly turn into something pretty difficult to keep controlled and up-to-date, specially when the developing work is shared between an extensive group of people. Keeping this in mind, it is pretty straightforward to understand [...]
