|The 2nd FORUM8 Design Conference
|Overview (Up&Coming Novemer, 2008)
This year, it is planned to release "Engineer's Studio", three-dimensional
analysis CAD that has been developed as our new strategic product. A developer
of "Maekawa Concrete Model" that is supported by Engineer's Studio,
Professor Koichi Maekawa, Dept. of Civil Engineering, the University of
Tokyo gave a special lecture at the beginning of the 2nd FORUM8 Design
Conference on recent subjects relating to maintenance of concrete structures.
|Presenting Diverse Subjects on Structures from Maintenance to Natural Disasters
and Environment with Advanced Solutions
FORUM8 held the 2nd FORUM8 Design Conference at Tokyo Conference Center
Shinagawa on September 19, 2008.
FORUM8 released a 3D analysis program for space-framed structures "UC-win/FRAME (3D)" in 2002. Following this, we held the first "UC-win/FRAME (3D)
Conference" in October 2003 for the purpose of hearing opinions from
the users and presenting new products and versions. Since then, the Conference
took hold as an important event in autumn. It has been expanded since 2007,
as the "Design Conference" held in parallel with "UC-win
/ UC-1 User Conference".
Technology Session was held in the afternoon, consisting of 4 main areas
of "Civil Engineering", "Architecture", "Design
CAD", and "Hydraulic Engineering" like the last time. Lectures
on the subjects set according to each area and explanation on our relevant
solutions were given in 4 different rooms, followed by sessions under the
Simultaneous interpretation service in three languages (English, Japanese,
and Chinese) was provided for some of the lectures to help audience and
speakers from abroad. Moreover, TV conference system was used for participants located at Osaka, Nagoya, Fukuoka, Shanghai,
and Seoul to take part in the sessions in the main room (Hall A).

The Conference started in Hall A at 11:00 in the morning with Sponsor's
Greetings by Yuji Ito, President of FORUM8.
Next, aforementioned Professor Koichi Maekawa from the University of Tokyo
gave the opening special lecture on "Nonlinear analysis and maintenance
of existing deteriorated RC / PC structures". Traditionally in the
performance assessment of an existing structure, resistance to earthquakes
has been a major element. Nowadays however, besides this it is more and
more required to estimate residual strength, fatigue life, or others. Focusing
on various cases that attracted attention in recent years, he explained
from the perspective of numerical analysis.
First, he listed many factors causing damage and deterioration in concrete
bridges, mentioning necessity of repair according to the patterns of damage.
Specific examples he listed included: 1) earthquake-proof repair conducted
for the pier with few problems of deterioration of steel; 2) verification
of earthquake resistance performance on the case of a railway bridge completed
over 100years before, to which seismic retrofit was applied by now after
suffering damage due to uneven settlement; 3) verification of earthquake
resistance performance on a seawater duct in an atomic power plant, on
the assumption that the structure of a complicated shape had caused critical
deformation; 4) an experiment on the residual performance of a pier when
horizontal force, torsion, and shear act at the same time. Through these
cases, he pointed out that it is important how to express cracking in concrete
and mechanical characteristics of reinforcement.
Next, with respect to the corrosion rate model of steel that "UC-win/WCOMD"
also supports, he explained the difference from the conventional model
and the advancement in simulation of steel corrosion. In specific, he made
a detailed presentation about the mechanism of how the strength rather
increases in the respective cases that the steel in the axial direction
like a beam gets corroded and has already cracks, and that of experiment
to apply shearing force to a large-scale beam with a crack previously produced
in the axial direction of the member due to thermal stress. He also mentioned
the influence of a huge earthquake on a seawater duct with steel corrosion.
Another case he explained was about the problem that alkali-aggregate reaction
occurred in a bridge structure, causing fracture of bending work in the
steel. It was a question whether it should be removed or maintained by
reinforcing. Then he introduced various kinds of examinations on impact
assessment method in a simple case, earthquake resistance performance in
the case without fixation of stirrup, impact on the structural performance
depending on the position of corrosion, and so on. He made an explanation
about some cases with numerical analysis. For example, when there is damage
in the fixed area, the situation can be worsened by repairing blindly,
while on the contrary the strength increases by covering the whole with
On the other hand, he said that earthquake and fatigue are only different
in the patterns such as of the number or level of loads, and that originally
nonlinear analysis technology can be applied to fatigue. It depends on
whether or not the material model can deal with the situation of high cycle,
as he explains.
Regarding this, it will be possible to deal with high-cycle cyclic stress
by adding a partial term to the traditional constitutive rule. He showed
a numerical analysis and other simulation cases by reflecting this with
a tool (UC-win/WCOMD).
In this context, Japan Society of Civil Engineers conducted calculation
to see the difference between the cases of sound situation and the situation
having damage in advance, when fatigue is applied. Compared with the case
of no damage, the case with a little damage showed obvious rapid decrease
of fatigue life. On the contrary, it was concluded that there was no significant
difference in the case of only one-time loading and deflection. He appealed
that the analysis result is open to public for the purpose of having the
third party examine its correctness by experiments.
Besides, he also mentioned verification of performance on an existing bridge
having initial degradation, forecasting of deflection and fatigue life
of the bridge superstructure against moving loads, and application cases
of analysis/simulation in design confirmation of a floating structure that
suffers salt splash and fatigue at the same time, etc. Among these studies,
he asserted that the answers would definitely be drawn as to whether the
results about durability or life are correct or not. However, since an
earthquake may not lead to verification even by monitoring for as long
as 50 or 100 years, he expects that with regard to earthquake damage, related
technology will be improved more and more by giving feedback of information
to engineers every time it is obtained.
Lastly, he again put an emphasis on the importance of an approach of developing
technology by combining estimate in the laboratory and verification based
on the reality, assuming that these cited examples were not fully verified.
<Technology Session> started at 1:00 in the afternoon. As written
above, it was divided into four areas of "Civil Engineering",
"Architecture", "Design CAD", and "Hydraulic Engineering".
For each area, different sessions were held in each room for four hours.
The following are the points of Special Lecture, User's Special Lecture,
and presentations by the developer as well as developing groups of our
| Civil Engineering Session
| Geotechnical Analysis
Professor Keizo Ugai, Civil and Geotechnical Engineering, Gunma University
gave the first lecture of Civil Engineering Session, "Disasters in
Intermediate and Mountainous Areas Caused by Recent Inland Earthquakes
-- the Results of Research and Applications of Dynamic FEM Analysis for
2004 Chuetsu earthquake -- 2007 Chuetsu Offshore earthquake -- 2008 Sichuan
earthquake -- 2008 Iwate-Miyagi Inland earthquake". Focusing on four
earthquakes that had occurred in recent years in Japan and China, he explained
their outlines, as well as the mechanism and characteristics of earth and
soil disasters accompanied with them. He paid attention to the fact that
the case of Sichuan earthquake is characteristic of rock slope failure
on a large scale, unlike the cases in Japan in which earth and weathered
soft rock occupy the large part of the landsliding mass. He pointed out
the importance of understanding the mechanism of landslide caused by earthquake,
and mentioned that numerical simulation such as FEM is essential in order
to prove the mechanism of slope failure in more detail. Since the studies
on earthquake disasters are mainly targeted on urbanized areas, emphasis
should be put also on intermediate and mountainous areas, as he claimed.
Subsequently, FORUM8 staff introduced "GeoFEAS3D", a software
program for 3D elast-plastic analysis of ground to be newly released. This
is the successor of the existing "GeoFEAS2D" for two-dimensions.
Showing pile foundation as an example, the staff explained the operation
procedures and functions of the new product aimed for creation and analysis
of a pile group ground model.
Prof. Keizo Ukai, Gunma University
| Environment and Energy
Next, Professor Nobuyoshi Yabuki, Division of Sustainable Energy and Environmental
Engineering, Graduate School of Engineering, Osaka University gave a special
lecture, entitled "Computerization of Civil Engineering Improved by
Environment and Energy". He gave a commentary on computerization of
the civil engineering field in Japan from the points of view of CALS/EC,
standardization of information on construction, adoption of three dimensions
such as CAD, product models, and VR in civil engineering, and computerized
construction. He paid attention to environment and energy as keys for promoting
them. For this reason, he mentioned the different problems relating to
environment and energy, as well as the stream towards building up a low-carbon
and recycling-oriented society. He cited "national land infrastructure
model" as a solution for those problems ranging in a wide variety,
depicting the idea of cyber infrastructure based on 3D product models,
links with the actual social infrastructure, and a picture of diverse applications
for environmental and energy problems. He cited "The Third Wave"
written by Alvin Toffler as a base for these ideas, and explained the impact
that the progress of information communication technology (ICT) has on
the society. He further showed his observation that computerization of
civil engineering that had been centered on 2D drawings is going to evolve
into 3D, system integration with data models, and making the real world
intelligent by integrated simulation, with response to environmental and
energy problems as a turning point.
Prof.Nobuyoshi Yabuki, Osaka University

divided easy slab bridges into simple bridges and rigid-frame bridges,
and explained the structures and applicable conditions for each type. He
further listed the characteristics of an easy slab bridge in terms of the
construction method, as follows:
1) Simple structure and low girder height
2) Supporting diverse planar structure
3) Easy construction and short work period
4) Capable of construction at a narrow and small space because of light
dead weight of the girder
5) Capable of divided execution considering existing roads at the time
of reconstruction of an existing bridge
6) Easy maintenance.
He also listed the characteristics of an easy rigid-frame bridge as follows:
1) Adopting an easy slab bridge for the superstructure
2) Improved earthquake proofness
3) Reduced size of the substructure by unifying superstructure and substructure
4) Mitigated impact on the surroundings because of minor influence of excavation.
5) Reduced cost because of no need for such devices as a bearing, an expansion
apparatus, and a falling prevention device.
With respect to the above points, our staff in charge presented the overview
of the latest development of a design calculation program for portal rigid-frame
bridges. He listed some points such as adopting a 3D model for an analysis
