Seismic response of liquid storage steel tanks with variable frequency pendulum isolator
KSCE Journal of Civil Engineering - Tập 15 - Trang 1041-1055 - 2011
The seismic response of liquid storage steel tanks (slender and broad) isolated with Variable Frequency Pendulum Isolators (VFPIs) is investigated under normal component of six near-fault ground motions. The continuous liquid mass is lumped as convective mass, impulsive mass and rigid mass. The corresponding stiffness associated with these lumped masses is worked out depending upon the properties ......
Information technology utilization to improve project team-owner relationship and project performance
KSCE Journal of Civil Engineering - - 2015
While prior research suggested a positive relationship between the use of particular Information Technology (IT) tools and organizational performance, very few published studies have attempted to assess the influence of IT usage on project team-owner relationship and the performance of capital facility projects. Thus, the first objective of this study is to validate a framework for assessing the a......
Seismic Active Earth Pressure of Infinite Width Backfilled Soil on Cantilever Retaining Wall with Long Relief Shelf under Translational Mode
KSCE Journal of Civil Engineering - Tập 27 - Trang 3285-3299 - 2023
In the area of high seismic intensity, there were few methods for calculating active earth pressure (Ea). Especially for the cantilever retaining wall with long relief shelf (CRW-LRS), the theoretical method lags behind the practical engineering. The seismic active earth pressure (ES) of the CRW-LRS subject to translational mode was researched. By finite element method (FEM), the failure mode of t......
Assessment of Flow Through Clay-sand Liners using Laboratory Models
KSCE Journal of Civil Engineering - Tập 22 - Trang 1684-1690 - 2017
Three laboratory models were designed to simulate a field section of a clay sand liner. The laboratory models were designed to test 10 cm thick Al Qatif clay sand liners with clay content of 15%, 20% and 25% overlain by agricultural soil and underlain by granular sandy material. The percolation through the clayey layer was measured for repeated watering following variable drying periods. 30 tests ......
A study on scan data matching for reverse engineering of pipes in plant construction
KSCE Journal of Civil Engineering - Tập 21 Số 6 - Trang 2027-2036 - 2017
Experimental Study of the Salt Transfer in a Cold Sodium Sulfate Soil
KSCE Journal of Civil Engineering - - 2019
Biomass-Based Iron Removal: Adsorption Kinetics, Isotherm and Machine Learning Modelling with Ocimum sanctum And Syzygium cumini
KSCE Journal of Civil Engineering - Tập 27 - Trang 5090-5108 - 2023
Iron concentrations in drinking water beyond the acceptable level adversely affect human health and aquatic life. Innovative chemical-based iron extraction processes exist, albeit being costly. Therefore, iron removal using easily accessible plants is the most sustainable alternative. The bioadsorption of iron by Ocimum sanctum Linn. leaves (OSL) and Syzygium cumini seed (SCS) biomass was examined......
Parametric Structural Calculation of Shield Linings for Large-Diameter Tunnels Based on the Shell-Spring Model

Assessment of expressway construction using Quality Performance Index (QPI)
KSCE Journal of Civil Engineering - Tập 17 - Trang 377-385 - 2013
Since quality control in expressway construction is generally performed by monitoring during the process of construction, it is difficult to perform a quantitative assessment of the level of quality in reality. In order to solve this problem and improve the level of quality, the Korea Expressway Corporation (KEC) has developed a Quality Performance Index (QPI) that quantitatively assesses the leve......
Functional Relationship of Parameters in Different Theoretical Models for Ground Settlement Caused by Shield Tunneling
KSCE Journal of Civil Engineering - Tập 24 - Trang 310-321 - 2019
The shield tunneling method has unique advantages and has been widely used in tunnel excavation. Therefore, it is important to study the ground settlement caused by shield tunneling. We considered the metro tunnel in Hohhot city, China, as a case study, and used various models to calculate the ground settlement separately. The optimal model was then identified by comparing the results with measure......
