...Helena Barros; Rui Faria; Carla Ferreira; Thomas Gernay; Mohamed Salah Dimia Purpose The paper aims to give an insight into the behaviour of reinforced concrete columns during and after the cooling phase of a fire. The study is based on numerical simulations as these tools are frequently used...

...Helena Barros; Rui Faria; Carla Ferreira; Koichi Maekawa; Chikako Fujiyama Purpose The paper aims to propose a rate‐dependent model of structural concrete in combination with the kinematics of condensed water. Design/methodology/approach First, the paper proposes the coupling model of water...

...Helena Barros; Rui Faria; Carla Ferreira; Mário Pimentel; Joaquim Figueiras Purpose The purpose of this paper is to present the implementation in a finite element (FE) code of a recently developed material model for the analysis of cracked reinforced concrete (RC) panels. The model aims...

...Giovanna Xotta; Valentina A. Salomoni; Carmelo E. Majorana Purpose Knowledge of the behavior of concrete at mesoscale level requires, as a fundamental aspect, to characterize aggregates and specifically, their thermal properties if fire hazards (e.g. spalling) are accounted for. The assessment...

... to model concrete's fracturing behavior. The information provided by the previous simulations is implemented in a statistical analysis to determine the size of the RVE. Findings The determination of the RVE size for quasi‐brittle materials is successfully achieved by means of a lattice‐particle model...

...Chunqi Lian; Yan Zhuge; Simon Beecham Purpose Porous concrete is a mixture of open‐graded coarse aggregate, water and cement. It is also occasionally referred to as no‐fines concrete or pervious concrete. Due to its high infiltration capacity, it is viewed as an environmentally sustainable paving...

...Alireza Ahangar‐Asr; Asaad Faramarzi; Akbar A. Javadi; Orazio Giustolisi Purpose Using discarded tyre rubber as concrete aggregate is an effective solution to the environmental problems associated with disposal of this waste material. However, adding rubber as aggregate in concrete mixture changes...

...Valentina Salomoni; Gianluca Mazzucco; Carlo Pellegrino; Carmelo Majorana Purpose The purpose of this paper is to investigate the bond behaviour between fiber reinforced polymer (FRP) sheets and concrete elements, starting from available experimental evidences, through a calibrated and upgraded 3D...

...Boris Trogrlic; Ante Mihanovic Purpose This paper aims to present a new numerical model for the stability and load‐bearing capacity computation of space reinforced‐concrete (R/C) frame structures. Both material and geometric nonlinearities are taken into account. The R/C cross‐sections are assumed...

...Valentina A. Salomoni; Gianluca Mazzucco; Carmelo E. Majorana Purpose This paper seeks to analyse 3D growing concrete structures taking into account the phenomenon of body accretion, necessary for the simulation of the construction sequence, and carbon dioxide attack. Design/methodology...

...Norberto Dominguez; Delphine Brancherie; Luc Davenne; Adnan Ibrahimbegović Purpose To provide a reinforced concrete model including bonding coupled to a classical continuum damage model of concrete, capable of predicting numerically the crack pattern distribution in a RC structure, subjected...

...Pavao Marović; Željana Nikolić; Mirela Galić Purpose To provide an insight in one relatively simple and efficient numerical model for analysing reinforced and prestressed concrete structures, and to raise a discussion leading to the creation of one universal and robust 3D algorithm. Design...

...M.H.F.M. Barros; A.F.M. Barros; C.A. Ferreira The aim of this paper is to obtain the analytical solution for the optimal design of reinforced concrete sections under ultimate design. The equilibrium equations of the section under bending moment and axial force in rupture are derived. The ultimate...
