    Seismic Study of Existing Steel Pipe Arch Water Pipe Bridge
    -Check damages of steel arch members and verify nonlinear seismic performance of legs-
    Program Used: Engineer's Studio®

    This work is a seismic survey of a 59-meter-long Langer stiffening type water pipe bridge in accordance with the guidelines for seismic construction methods for waterworks facilities. In the basic design of the seismic reinforcement, the seismic resistance of the bridge was verified by nonlinear dynamic analysis, and the reinforcement methods were compared for the areas where the bearing capacity was insufficient. As a result of the comparative study, the thickening of the back side was applied for the movable side, and the carbon fiber winding and the thickening of footing for the fixed side. As for the temporary construction method, the clamping method was used after considering the river conditions such as the river inhibition ratio. In the seismic diagnosis survey, detailed investigations such as pipe thickness measurement, neutralization test, and compressive strength test were carried out, and a seismic resistance verification was carried out to propose the proper reinforcement method.

    United Seismic Performance Verification of Civil Engineering Facility and Architectural Facility
    -Reproduce behaviors during earthquakes using dynamic analysis-
    Program Used: Engineer's Studio®

    The seismic performance of large-scale drainage pump stations, which consist of a large underground water storage tank and a multi-story building facility above ground, has been verified separately for civil engineering facility and building facility. However, there comes a question that it is inconsistent to use different compliance standards, different analysis methods, and different evaluation indices for verification of those structures, even though the facility is structurally and functionally the same. Also, there is another question whether the actual behaviors during earthquakes and the process of damage generation have not been sufficiently reproduced, and whether the methods and scale of countermeasures have not been optimized. Here, this work proposes a method to verify the seismic performance of large-scale drainage pumping stations through dynamic analysis, by creating an analytical model integrating underground civil engineering facilities and above-ground building facilities, and applying actual seismic motion waveforms as external forces.

    Study on Bearing Capacity of RC Beam Members Using Nonlinear Structural Analysis Program
    -Beyond the boundary of civil engineering and architecture-
    Program Used: Engineer's Studio®, WCOMD Studio

    In this study, nonlinear finite element analyses based on the experimental results of flexural and shear fracture types were conducted for RC beams, which are the most basic members, and compared with the bearing capacity of each of civil engineering and building standard to evaluate bearing capacity based on material damage beyond the framework of civil engineering and architecture. The analytical results of both flexural and shear fracture types well captured the characteristics of the phenomena in the experiment, indicating the possibility of rational evaluation of bearing capacity beyond the boundary of civil engineering and architecture by using material damage for evaluation.

    Level 2 Seismic Performance Verification for Pile-Bent Piers
    -Study of seismic performance of the entire bridge by dynamic nonlinear analysis-
    Program Used: Engineer's Studio®

    Pile-bent piers are constructed by driving steel or concrete piles into the supporting ground, raising the piles to a specified height, and connecting the pile heads with a reinforced concrete structure. Many pile-bent piers were constructed between 1960 and 1970 because of their economic efficiency and ease of construction. However, they have been discontinued due to flood control problems, and it has been confirmed that their seismic resistance is often insufficient to the current design loads. In order to improve the seismic resistance of the existing piers, various types of reinforcement have been studied, and in this work, the seismic performance of the pile-bent piers against Level 2 earthquake was verified.

    Three-Dimensional Dynamic Nonlinear Analysis of a New Five-Span Continuous Steel Pedestrian Deck Bridge-Compact structural investigation under limited space conditions-

    Program Used: Engineer's Studio®

    This work is the preliminary design of a steel pedestrian deck bridge designed to improve and activate the flow of people heading to a famous tourist and commercial facility. A compact design was required since the bridge is located in the center of the city, and the area of construction is limited to the width of the current sidewalk, which has some buildings nearby. Therefore, the control points for the study were arranged, and the dimensions of the upper and lower structures were determined to satisfy these conditions, and the members and foundations were examined by three-dimensional dynamic nonlinear analysis.

    Level 2 Seismic Study of π-Shaped Rigid-Frame Bridge with PC Diagonal Members
    -Reevaluate the design based on the old standard by the current standard-
    Program Used:
    Engineer's Studio®

    This bridge is a new π-type rigid-frame overpass with PC diagonal members and was designed based on the 2002 Specifications for Highway Bridges. However, when verifying the bridge using the 2017 Specifications for Highway Bridges, it was found that the limit values were satisfied for the normal and Level 1 seismic design, but not for the Level 2 seismic design. In this work, time response analyses were performed to ensure the seismic performance in accordance with the 2017 Specifications for Highway Bridges, Part V Seismic Design.

    Single Column Dynamic Analysis by Modeling Pier Frame and Deep Foundation
    -Permitted load verification of Langer bridge piers for L1 and L2 earthquake-
    Program Used:
    Engineer's Studio®

    This is a seismic reinforcement design of a two span through Langer bridge with composite slab girders. The entire bridge was modeled in three dimensions and dynamic analysis was performed. As for the bridge piers, which are nonlinear elements, a single-column dynamic analysis was conducted separately to examine the verification items specified in the Specifications for Highway Bridges, Part V Seismic Design. In the single-column dynamic analysis, the geotechnical data from the existing construction documents were used to model the deep foundation.

    Response Seismic Method of Ground
    -One-section response seismic method for water-conducting tunnels-


    Program Used:
    Geo Engineer's Studio

    In this analysis, the cross-sectional force of the lining of the conduit tunnel during an earthquake was calculated. One analysis model case is with no loosening area and another is with the loosening area. There are two methods of loading the seismic load: one is to uniformly apply the horizontal design seismic intensity using the response seismic intensity method, and the other is to load the seismic load as an external force due to earth pressure, assuming that there is a loosening area. The analyses were performed for total of 4 analysis, which are 2 analysis models and 2 load conditions. Of these, the method of soil pressure loading was used for the response seismic method in the case with no loosening area and for the case with loosening area.

    Comparison of seismic test result by using 2D and 3D model of existing water tank
    Program:Engineer's Studio®
    2D section models are often used for designing water tank structure, but the validity of the models are sometimes unreliable when the shape is complex or the size is unique. In this work, the test is conducted by using 2D section models as usual at first. After that, as a proposal, 3D models using plate element same as the actual structure are created and analyzed to compare the results between 2D model and 3D model.

    Seismic performance test using observed seismic motion
    Program:Engineer's Studio®
    With the increasing demands for seismic test and seismic countermeasure in recent years, it is necessary to understand the degree of lack of seismic performance of each facility in order to determine the necessity and priority of seismic measures among many facilities. At that time, the assessment based on the actual situation will result in the efficient seismic measure and cost reduction. Although seismic design methods have been established for various construction types, there are few test records on the damage to headworks. This report is an example of verifying the seismic performance of the headworks by using actual observed seismic motion and comparing the consistency of damage status between the actual damage situation and the test result.
