Joint Modelling of Drought Severity and Duration using Copula Theory: A Case Study of GhanaKSCE Journal of Civil Engineering - Tập 27 - Trang 1850-1865 - 2023
Gyamfi Kwame Adutwum, Eun-Sung Chung, Mohammed Sanusi Shiru, Shamsuddin Shahid
Analysing and understanding the occurrence and development of droughts is of great significance in mitigating drought impacts. This study assessed the possible changes in the joint distribution of drought duration and severity in two major cities of Ghana, Accra and Yendi. The duration and severity of droughts, estimated using the Standardized Precipitation Index (SPI), were determined based on ru...... hiện toàn bộ
Seismic response of liquid storage steel tanks with variable frequency pendulum isolatorKSCE Journal of Civil Engineering - Tập 15 - Trang 1041-1055 - 2011
V. R. Panchal, R. S. Jangid
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 ...... hiện toàn bộ
Characteristics of a Large-Scale Deep Foundation Pit Excavated by the Central-Island Technique in Chengdu Soft ClayKSCE Journal of Civil Engineering - Tập 26 - Trang 2610-2623 - 2022
Dongxing Ren, Chao Kang, Huanhuan Liu, Yin Li, Jilin Wang
A large-scale foundation pit, 25,720 m2 (127 m × 213 m), was excavated to a depth of approximately 20 m by the central-island technique from 2012 to 2013 in Chengdu, China. This paper aims to comprehensively study the deformation behaviours of the foundation pit during excavation and investigate the primary factors affecting the deformation behaviour of the foundation pit. The deformation characte...... hiện toàn bộ
Information technology utilization to improve project team-owner relationship and project performanceKSCE Journal of Civil Engineering - - 2015
Li-Ren Yang, Chung-Fah Huang
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...... hiện toàn bộ
A New Method based on Centrifuge Model Test for Evaluating Ground Settlement Induced by TunnelingKSCE Journal of Civil Engineering - Tập 23 - Trang 2426-2436 - 2019
Hongpeng Lai, Jian Zhang, Lianyang Zhang, Rui Chen, Wanjing Yang
Current methods for evaluating the ground settlement due to tunneling in loess do not fully consider the special engineering properties of loess. This paper first studied the ground settlement due to tunnel construction in loess by conducting a uniquely designed centrifuge model test. Then the ground settlements were calculated using a currently widely used method and compared with the measured va...... hiện toàn bộ
