Improving Damaged Reinforced Concrete Beam Failure Behavior Using Externally Bonded UHPFRCCs System
International Journal of Civil Engineering - Tập 21 - Trang 67-79 - 2022
Majed A. A. Aldahdooh, Rami J. A. Hamad, Mohammed J. K. Bashir, Norazura Muhamad Bunnori, Megat Azmi Megat Johari, Said Almaawali
This study aims to examine the failure behaviour of damaged reinforced concrete (RC) beams retrofitted using externally bonded ultra-high-performance fibre-reinforced cementitious composites (UHPFRCCs) systems at different levels of damage levels. To overcome the sudden failure in shear at supports, one strip of UHPFRCCs was bonded on the tension face with four short strips on vertical sides cover... hiện toàn bộ
Non-associative Fractional-Order Bounding-Surface Model for Granular Soils Considering State Dependence
International Journal of Civil Engineering - Tập 17 - Trang 171-179 - 2017
Yifei Sun, Yufeng Gao, Yang Shen
The constitutive behaviour of granular soil is usually non-associative and depends on the soil density and pressure. To simulate such dependence of the non-associative stress–strain response on material state, two distinct yielding and plastic potential surfaces were usually suggested in the traditional elastoplastic models, which, however, made the model to become complex. To solve this problem, ... hiện toàn bộ
Variation of Resilient Modulus with Soil Suction for Cohesive Soils in South China
International Journal of Civil Engineering - Tập 16 - Trang 1655-1667 - 2018
Junhui Zhang, Junhui Peng, Jue Li, Jianlong Zheng
The resilient modulus, MR, of subgrade soils had been used extensively as an important unbound material property in the pavement design and analysis. The stress state and the humidity of cohesive soils have significant impacts on the resilient modulus. To predict the resilient modulus of cohesive soils in South China, the material indicator tests, an improved repeated load triaxial test and the pr... hiện toàn bộ
Experimental and Numerical Analyses of Single Pedestrian Walking on a Hollow Core Concrete Floor
International Journal of Civil Engineering - Tập 17 - Trang 1201-1209 - 2018
Fangzhou Liu, Jean-Marc Battini, Costin Pacoste
The purpose of this paper is to study experimentally and numerically the dynamic response of a hollow core concrete slab due to a single pedestrian. To achieve this aim, a test structure consisting of six hollow core concrete elements of dimension 10 m × 1.2 m has been built. A finite element model of the structure based on orthotropic shell elements has been implemented. The accuracy of the finit... hiện toàn bộ
Hanoi Cohesive Soil in Salt-Affected Conditions: Soil Properties and 2D Consolidation Analysis
International Journal of Civil Engineering - Tập 18 - Trang 137-150 - 2019
Nguyen Ngoc Truc, Lena Mihova
The paper focuses on the geotechnical experiments and numerical simulation of 2D consolidation analysis for the cohesive soils fully saturated by solutions of four salt concentrations, i.e. 0.0, 9.9, 19.8, and 33.0 g/L. The experiments were carried out on undisturbed soil samples taken from the boreholes in Hanoi area where the subsoil has not been affected by saline intrusion yet. The composition... hiện toàn bộ

A Nonlinear Model to Predict Drivers’ Track Paths Along a Curve
International Journal of Civil Engineering - Tập 14 - Trang 271-280 - 2016
Gaetano Bosurgi, Nicola Bongiorno, Orazio Pellegrino
This study proposes a prediction model about the trajectories a vehicle, in isolated conditions, along a curve of a road. As we know, the road environment induces stress on users and, under certain conditions, influences driving behavior. It is of advantage then, to isolate and identify those conditions from among the numerous variables, which are actually the most significant so as to prevent or ... hiện toàn bộ
Nonlinear Finite Element Modeling of Shear-Critical Reinforced Concrete Beams Using a Set of Interactive Constitutive Laws
International Journal of Civil Engineering - Tập 14 - Trang 507-519 - 2016
Vahid Broujerdian, Mohammad Taghi Kazemi
Complex nature of diagonal tension accompanied by the formation of new cracks as well as closing and propagating preexisting cracks has deterred researchers to achieve an analytical and mathematical procedure for accurate predicting shear behavior of reinforced concrete, and there is the lack of a unique theory accepted universally. Shear behavior of reinforced concrete is studied in this paper ba... hiện toàn bộ
Discrete Element Modeling of Drained Triaxial Test: Flexible and Rigid Lateral Boundaries
International Journal of Civil Engineering - Tập 16 - Trang 1463-1474 - 2018
Seyed Mohammad Binesh, Ehsan Eslami-Feizabad, Reza Rahmani
In the present paper, drained triaxial test on granular materials is simulated by discrete element method. Two types of boundary conditions including rigid and flexible boundaries are modeled in the tests. To simulate flexible boundary condition, a new algorithm based on linking the MATLAB and PFC3D codes is proposed. In this algorithm, triaxial test samples are simulated in PFCD3D and the spatial... hiện toàn bộ
