Concrete structures’ service life lasts decades. In order to deal with all the probable degradations and deteriorations in the whole life span, the concept of concrete structures’ Life-Cycle Design was introduced into China in the 1980s. However, until this day, Life-Cycle Design is still more of a concept to most structure designers and engineers, rather than a practical method. This paper pro...

This paper presents a methodological approach of wide generality for assessing the reliability of reinforced and prestressed concrete structures. As known, the numerical values of the parameters which define the geometrical and mechanical properties of this kind of structures, are affected by several sources of uncertainties. In a realistic approach such properties cannot be considered as deter...

The aim of this review article is to examine solutions and challenges associated with composite construction. Structural steel and concrete, each of the two materials can be used to its best advantage and, therefore, composite structures have proved economical in terms of overall cost. Combination of steel and concrete systems has been conceived on the premises that each type of construction of...

This work focuses on assessing costs and effectiveness of climate adaptation strategies for existing reinforced concrete structures subject to chloride penetration and climate change. We will study on existing reinforced concrete structures built in France at different years under different building codes. Concerning environmental actions, we considered historical meteorological data and two cl...

There is a growing need for the rehabilitation, repair, and upgrading of concrete structures such as bridges and buildings. The repair or rehabilitation of reinforced concrete structures often offers a lower cost alternative to rebuilding, and it is traditionally achieved by bonding steel plates to the tensile face of a reinforced concrete member. The shear strength can be enhanced with plates ...

The paper summarizes the main outcomes achieved within the framework of the research project “Nonlinear fracture mechanics of concrete using stochastic finite elements and random fields”. The project focused on randomization of nonlinear finite element analysis of concrete structures. Theoretical as well as practical application aspects are presented emphasizing the conceptual framework and key...

Accurate constitutive models of the constituent materials in a reinforced concrete (RC) section, namely, unconfined concrete, confined concrete and reinforcing steel are necessary in fiber-based discretization of RC components for use in nonlinear analysis of RC structures. This paper examines the sensitivity to different constitutive models in predicting the inelastic seismic behavior of RC fr...
