Applying the residual strength evaluation method using degradation level
check to jetties
- Proposal of a new strength evaluation method using a loading experiment
and general regular check results -

|
| Among harbor structures, jetties are especially in severe environments
against salt damage and need more appropriate maintenance than other structures.
However, there are not so many studies on residual strength and seismic
performance of degenerate jetties. In addition, an evaluation of jetties'
remaining strength normally requires a detailed constant check and diagnosis
that takes a lot of cost and time. That is why companies need simple strength
evaluation methods. This research is an suggestion of a simple residual
strength evaluation method that performs a loading experiment for each
degradation level to reveal the relationship between the degree of degeneration
and the remaining strength and export the results to general structure
analysis software programs. |

Seismic performance evaluation according to damage on material
- Proposing a reasonable shear strength evaluation method for underground
structures -

This work proposes a reasonable shear strength evaluation method for underground structure of sewage facilities by using a damage indicator that does not depend on the element dimension or material physical model. After considering the applicability of damage indicator on the basis of a static load experiment for an underground box culvert, shear strength against underground walls of sewage facility was evaluated. The work found that it can execute a more reasonable evaluation than the current evaluation using shear strength.

Stress analysis on the branch point of steel deck box girder bridge
- Stereoscopic FEM model analysis by using plate and shell -
KATAHIRA & ENGINEERS INC. |
|
|
| Program: FEMLEEG |
|
|
 |
|
Poster PDF(1,143KB) |
|
| Although the dynamic analysis by frame is already done for the analysis target bridge, it is estimated that the stress will focus on the branch point because of the special structure that separates on the intermediate fulcrum. If this part is seriously damaged, it will take a lot of time to restore the bridge, and that may block a passage of emergency vehicles. In this work, a stereoscopic analysis model using plate and shell was created for more detailed analysis. |

CFD analysis simulation of traditional architecture
- Wind speed analysis outside "Futatsuya" -
Kagoshima University |
|
|
| Program: DesignBuilder |
|

Poster PDF(987KB) |
|
| This is a simulation using the CFD analysis for houses being constructed
in Kagoshima city. This house is modeled on the "Futatsuya" that
is a traditional house constructed widely in Southern Kyushu district.
By focusing on the Futatsuya house model and the wind blowing around, this
simulation performed by modern technologies tests and analyzes the effectiveness
of traditional residences rooted in the region based on wisdom and experience
cultivated in the era with undeveloped technology. |

Seismic performance verification for PC snow shed against L2 earthquake
- Towards making a snow shed to withstand a large earthquake -
NIHON SAMICON CO., LTD. |
|
|
| Program: Engineer's Studio® |
|
|
 |
|
Poster PDF(910KB) |
|
| A snow shed is the best method to protect roads and railroads from large
fallen snow and snowslide. So far, the seismic method against the L1 earthquake
has been used for the seismic design of snow shed. Because of the revision
of the standards, however, an need for designs against L2 earthquake is
increasing. The seismic performance test by non-linear time history response
analysis (dynamic analysis) is executed in lateral direction that has more
strict conditions to check the safety at L2 earthquake. |

Seismic verification of coastal embankment
- Liquefaction determination and seismic deformation analysis against structure
-
Cosmo Consultants Co., Ltd |
|
|
| Program: GeoFEAS 2D |
| This is a review of coastal embankment in Southern Kyushu region at earthquake.
After evaluating the liquefaction of the ground, the stability of structures
at L1 earthquake was checked. The deformation amount was estimated by the
static varification method, and the seismic performance was also evaluated.
As a result, the deformation amount at liquefaction was determined to be
within the allowable value. |

Seismic performance verification for additional piles against L2 earthquake
and tsunami
- Frame analysis against additional pile foundation of coastal levee -
Marine Support Engineering |
|
|
| Program: Engineer's Studio® |
| Piles (cast-in-place pile dia.1000) were added to the existing coastal
levee foundation (steel pipe pile dia. 1000) since the support force was
not enough. When the bottom slab length becomes longer due to additional
piles, the thickness of the current bottom slab cannot be thicker. The
bottom slab cannot be considered as a rigid, and it requires a frame analysis
test considering its rigidity. The review was done with models with rigid
bottom slab, and the test against level 2 earthquake and tsunami load which
foundation test results are strict was executed by using Engineer's Studio®. |

Seismic test for a steel intake tower
- Interaction between a steel tower and a multistage telescope type cylinder
gate at earthquake -
APPLIED TECHNOLOGY CO., LTD. |
|
|
| Program: Engineer's Studio® |
| The multistage telescope type cylinder gate is mainly used for the water
withdrawal at dam. Its elastic door mechanism according to the water height
in dam enables the stable continuous water withdrawal from the entrance
on the top. The gate is separated from the tower around them, and it causes
complex movements of the door and tower powered by suspending rope and
guide roller. In this work, the suspending rope is modeled with a cable
element and the guide roller with a spring element, and the seismic test
is executed by a time history response analysis considering the interection
between the gate and tower. |

Evaluating damage on existing bridge foundation caused by L2 earthquake
- Evaluation of existing foundation by pushover analysis focused on the
displacement sudden increase point -
Wakasuzu Co., Ltd. |
|
|
| Program: Pier 3D bar arrangement, Foundation 3D bar arrangement |
| The Specifications for Highway Bridges (March 2012) says that the standard
foundation yield is a condition either "all piles have plastic body"
or "the pile head reaction of one column reaches the limit of press
bearing capacity". However, these conditions do not always match the
displacement explosion point at inertia action position of superstructure.
Sometimes the horizontal strength is kept even after becoming these conditions.
This work is a calculation of plasticity rate of the existing pier foundation
by executing a pushover analysis gradually increasing the horizontal seismic
intensity on foundation piles by 0.01 and determining the foundation yield
horizontal seismic intensity (khyF) of foundation from the displacement
explosion point in each model. |
