Strength and ductility of rubberized concrete beams with micro-reinforcement
Asian Journal of Civil Engineering - Tập 21 - Trang 1-15 - 2019
R. Karthikeyan, P. N. Raghunath, K. Suguna
A laboratory study has been conducted on R.C beams with coarse aggregate replaced by pretreated supplementary aggregates and micro-reinforcement included. For this investigation, seven full-scale beams of length 3 m and having a size of 150 mm × 250 mm were fabricated and tested for their strength and ductility. One beam was treated as reference specimen. Remaining six beams were fabricated with p...... hiện toàn bộ
Estimation of elastic and inelastic seismic behavior of reinforced concrete framed structures
Asian Journal of Civil Engineering - - Trang 1-12 - 2023
Rachana Bajaj, Shalini Yadav
The paper titled “Estimation of Elastic and Inelastic Seismic Behavior of Reinforced Concrete Framed Structures” aims to investigate the seismic performance of reinforced concrete framed structures using both elastic and inelastic analysis methods. The study focuses on developing a reliable and accurate method to estimate the seismic behavior of such structures under different levels of seismic lo...... hiện toàn bộ
Numerical modeling of the pathological case of a damaged tunnel application to Djebel El-Ouahch tunnel (east–west highway)
Asian Journal of Civil Engineering - Tập 19 - Trang 913-925 - 2018
Aicha Berkane, Toufik Karech
This work deals with a numerical analysis of a pathological case of a part of tunnel T1 of Djebel El-Ouahch which suffered a collapse. The pathological analysis of state of stress and state of deformation in the soil and in the tunnel wall was examined. Numerical modeling is performed in 3D space using the PLAXIS 3D TUNNEL calculation code which is based on the finite element method; the behavior ...... hiện toàn bộ
Using AHP to prioritize the corruption risk practices in the Iraqi construction sector
Asian Journal of Civil Engineering - Tập 22 - Trang 1281-1299 - 2021
Semaa Hazim Najim Alani, Ahmed Mohammed Raoof Mahjoob
Corruption is an old phenomenon, but what is new is the increase in its scale and its diversified methods. Both advanced and developing countries have suffered to the point where corruption threatens to degrade communities and interrupt the progress of economic development. There are common issues in corruption, which is defined as the illegal obtainment of money, and the problem of corruption has...... hiện toàn bộ
Predicting building damage grade by earthquake: a Bayesian Optimization-based comparative study of machine learning algorithms
Asian Journal of Civil Engineering - - 2024
Mohammad Al-Rawashdeh, Moh’d Al Nawaiseh, Isam Yousef, Majdi Bisharah, Sajeda Alkhadrawi, Hamza Al-Bdour
Predictive modeling of shear strength in fiber-reinforced cementitious matrix-strengthened RC beams using machine learning

Rupesh Kumar Tipu, Vandna Batra, Suman Suman
Generating seismic fragility curves of RC frame building using NSPA and IDA
Asian Journal of Civil Engineering - Tập 24 - Trang 523-538 - 2022
Kaushik Gondaliya, Jignesh Amin, Vishisht Bhaiya, Sandip Vasanwala, Atul Desai
In the last two decades, seismic fragility analysis for RC frame buildings has become critical in evaluating structure risk and safety margin due to lateral loads. In the study, the four-storey RC frame building is designed per the latest IS 1893 for seismic zone-V. Multiple fragility analysis methodologies are compared using nonlinear static pushover analysis and incremental dynamic analysis (IDA...... hiện toàn bộ
Automated rotational- and scaling-invariant image-based crack width monitoring with sub-millimeter accuracy and self-numbering label
Asian Journal of Civil Engineering - Tập 21 - Trang 741-749 - 2020
Xingzhuang Zhao
Crack width plays an important role in the automated serviceability and safety monitoring of bridges and buildings. The proposed three-marker method (TMM) tries to improve the robustness and accuracy of the traditional image-based crack width monitoring by introducing the self-numbering markers. The methodology of the TMM technique for the crack width monitoring is introduced and the procedure of ...... hiện toàn bộ
One-dimensional convolutional neural network for damage detection of structures using time series data
Asian Journal of Civil Engineering - - Trang 1-34 - 2023
Viet-Linh Tran, Trong-Cuong Vo, Thi-Quynh Nguyen
Structural health monitoring (SHM) has been a continuous interest in civil engineering for decades because of its importance to the smooth operation of structures. Machine learning (ML) and deep learning (DL) methods have been successfully applied for damage detection of structures. However, the traditional ML algorithms heavily depend on the features’ choice and the classifier; therefore, their a...... hiện toàn bộ
Influence of load position on critical lateral torsional buckling moment of laterally restrained beam at tense flange
Asian Journal of Civil Engineering - Tập 19 - Trang 839-848 - 2018
T. Belaid, F. Ammari, R. Adman
This paper presents an alternative computation approach for the critical moment of lateral-torsional buckling of a simply supported steel beam with continuous lateral elastic restraint. The total potential energy is first established for the lateral-torsional buckling of beams under uniform bending moment and uniform loading. By introducing dimensionless parameters, the dimensionless critical buck...... hiện toàn bộ
