Faculty Members and Research Interests, 2007
Dr. Amorn Pimanmas
Associate Professor
B.Eng. in Civil Engineering, Chulalongkorn University, Thailand
M.Eng. & Ph.D. in Civil Engineering, University of Tokyo, Japan
Areas of Specialization: Behavior, analysis and evaluation of damaged reinforced concrete members and
structures; Nonlinear finite element analysis of reinforced concrete (RC) mechanics; Maintenance, repair and
inspection of RC buildings.
Research Interests:
Strengthening of Reinforced Concrete Members
by Fiber Reinforced Composite
Many existing reinforced concrete structures need
strengthening to upgrade the load bearing capacity.
Recently, fiber reinforced composite (plate and sheet)
has been increasingly used to elevate the flexural
capacity of the member. However, because of high
stress concentration near the plate ends, peel-off
failure takes place before fiber rupture. This reduces
the efficient usage of fiber reinforced material. The
research aims to prevent anchorage failure. A
numerical analysis will be attempted to predict the
anchorage failure load.
Evaluation of Damaged Reinforced Concrete
Members
This research aims to evaluate the structural behavior
of reinforced concrete members damaged by precracks.
This is a necessary step towards the
evaluation of the whole structure. Experimental
programs will be arranged to study the behavior of
pre-cracked reinforced concrete members. Here, we
classify the target members into 2 cases; that is, RC
members governed by concrete compression failure
(deep beams, beams with transverse bars) and RC
members governed by concrete tension failure (lightly
reinforced beams, beams with no transverse bars).
The aim is to formulate a universal theory that
explains both the compression and tension behavior
of pre-cracked RC elements and members.
Dr. Krishna Murari Neaupane
Associate Professor
B.Eng. (First Class, First) Dept. of Mining & Geological Engineering, The University of Calcutta, India
M.Eng. in Geotechnical Engineering Program, Asian Institute of Technology (AIT), Thailand
D.Eng. in Geotechnical Engineering, Saitama University, Japan
Areas of Specialization: Numerical methods in geotechnical engineering; Mass transfer through porous media
and its application to geoenvironmental problems; Underground space development and tunneling.
Research Interests:
Application of Coupled Processes to
Geo-environmental Engineering
Many geo-environmental problems, including nuclear
waste repository and sanitary landfill problems,
involve three physical processes: mechanical, thermal
and hydrological. Though one of these three physical
processes plays a more dominant effect on the
response of the system, the effect of the remaining
processes may not be neglected, and a coupling of
one or more processes is required for engineering
analysis. The primary objective of this research is to
model various geo-engineering problems using a
coupled approach.
Soft Computing: Artificial Neural Networks, GIS,
ANP
Geological engineering is often considered as an
imprecise area of civil engineering. Artificial neural
network can be a useful tool to deal with geotechnical
'black-box' problems. Major focus is on the application
of Geographic Information Systems (GIS) to the field
of geo-environmental engineering. Applications of
ANP and BPNN within the GIS framework are under
consideration.
Tunneling and Underground Excavation
In rock tunneling, research interests are mainly in the
area of stress distribution around underground
openings, numerical analysis, geotechnical monitoring
and tunnel safety. In soft ground tunneling, major
concerns are ground deformation around openings
and settlement due to subsurface excavation.
