    Long-term Deterioration of High Damping Rubber Bridge Bearing

    Get PDF
    In recent years,high damping rubber(HDR)bridge bearings have become widely used because of the excellent ability to provide high damping as well as flexibility. However, there are few systematic studies on the deterioration problems of HDRs during their service life, and usually the long-term performance was not considered in the design stage. In this research, through accelerated thermal oxidation tests on HDR blocks, the property variations inside the HDR bridge bearing are examined. A deterioration prediction model is developed to estimate the property profiles. Then using a constitutive model and carrying out FEM analysis, the behavior of a HDR bridge bearing during its lifespan is clarified. A design procedure is proposed that takes the long-term performance in the site environment into consideration.journal articl

    Various driving simulators are being increasingly used, however, they are generally expensive and devices are large. From this point of view, last year, we studied three-dimensional computer graphics, and made a simple driving simulator program by Java3D. In this paper, we continue the study, and try to improve the program and implement the driving simulator.departmental bulletin pape

    Driving simulators are being increasingly used for training of driver's education, entertainment, research facilities for many purposes, and so on all over the world. However, they are generally expensive, and the devices are large. Moreover, recently, a new type of traffic accidents caused by call with the mobile telephone and driving of senior citizens is outstanding. Thus, we think that the study of simple driving simulator is very meaningful. In this paper, we study three-dimensional computer graphics, and try to make a simple driving simulator program by the Java3D. We want to aim at the practical system little by little.departmental bulletin pape

    上路式鋼製補剛アーチ橋の地震時面内終局挙動に関する研究

    Get PDF
    Nonlinear dynamic response analysis is carried out to investigate the ultimate behavior of upper-deck type steel arch bridges subjected to severe earthquake waves. It is observed from the numerical analysis that the energy absorption of the upper deck reduces the damage in arch ribs. Furthermore, the geometrical nonlinearity has a large effect on the seismic behavior of arch bridges. However, the effect of vertical acceleration is not always significant. As long as the magnitude of the equivalent plastic strain is small, the effect of constitutive models is also small.application/pdfjournal articl

    非線形はりモデルを用いた鋼製橋脚の耐震解析における幾何学的非線形性とせん断変形の影響

    現行の耐震設計において単柱式鋼製橋脚の終局挙動を解析する際には,せん断変形を無視したBernoulli-Eulerはり理論による幾何学的非線形解析が一般的に行われている。ここでは,Bernouli-Eulerはり理論による解析の妥当性,精度の検討をせん断変形の影響を考慮したTimoshenkoはり理論による幾何学的非線形解析と比較することによって行った。Bernoulli-Eulerはり理論による解析の精度を支配する2つの構造パラメータを同定し,これらのパラメータにより相対差を評価するための算定式を誘導した。これより,鋼製橋脚の耐震解析においては,せん断変形の影響が大きく,背の低い橋脚の耐震設計を行う際にはこの影響を無視できないことがわかった。一方,幾何学的非線形性の影響は,極端に細長比が大きい場合や鉛直荷重が大きい特別の場合を除き,一般的に無視できる。 In the seismic design, the ultimate behavior of steel piers are usually predicted by the nonlinear Bernoulli-Euler beam model where shear deformation is ignored. Here, the validity and accuracy of the Bernoulli-Euler beam model. Then, an equation is derived to estimate the accuracy of this beam model in terms of the two parameters. From this equation, it is shown that the shear deformation has a big influence on the ultimate behavior of steel piers and cannot be ignored for the stocky piers. In contrast to the shear deformation, the geometrical nonlinearity can be normally ignored except for the steel piers with extremely large slenderness ratio and high axial force ratio.application/pdfjournal articl

    Driving simulators are used for training of driver's education, entertainment such a racing game, research purposes in the area of human factors and medical research, and so on. However, in general, their devices are large and expensive. Thus, we have continued studying the simple driving simulation software to work on a personal computer [5,8]. In this paper, we mainly deal with the pavement marking of speed lane, and try to improve the program of driving simulator. The algorithm is implemented in the Java3D on a personal computer.departmental bulletin pape
