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

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
Assessment of Flow Through Clay-sand Liners using Laboratory ModelsKSCE Journal of Civil Engineering - Tập 22 - Trang 1684-1690 - 2017
Muawia Dafalla, Ali Obaid
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
