Shake Table Test and Numerical Analysis of a Bridge Model Supported on Elastomeric Pad Bearings

Elastomeric pad bearings are widely applied in short- to medium-span girder bridges in China, with the superstructure restrained by reinforced concrete (RC) shear keys in the transverse direction. Field investigations after the 2008 Wenchuan earthquake reveal that bearing systems had suffered the most serious damage, such as span falling, bearing displaced, and shear key failure, while the piers and foundations underwent minor damage. As part of a major study on damage mechanism and displacement control method for short- to medium-span bridges suffered in Wenchuan earthquake, a 1:4 scale, two-span bridge model supported on elastomeric pad bearings were recently tested on shake tables at Tongji University, Shanghai. The bridge model was subjected to increasing levels of four seismic excitations possessing different spectral characteristics. Two restraint systems with and without the restraint of RC shear keys were tested. A comprehensive analytical modeling of the test systems was also performed using OpenSees. The experimental results confirmed that for the typical bridges on elastomeric pad bearings without RC shear keys, the sliding effect of the elastomeric pad bearings plays an important role in isolation of ground motions and, however, lead to lager bearing displacement that consequently increases the seismic risk of fall of span, especially under earthquakes that contain significant mid-period contents or velocity pulse components. It is suggested from the test results that RC shear keys should be elaborately designed in order to achieve a balance between isolation efficiency and bearing displacement. Good correlation between the analytical and the experimental data indicates that the analytical models for the bearing and RC shear key as well as other modeling assumptions were appropriate.     

Constructing and practicing feminist pedagogy in Taiwan using a field study of the Twenty-Five Ladies Tomb

Drawing on theories of space, gender, and participatory learning, central concepts in feminist pedagogy, the author designed a university-level general-education course that took the Twenty-Five Ladies Tomb in southern Taiwan as the focus of a field study and class discussion. This local gendered site, which commemorates a 1973 ferry accident that killed 25 unmarried young women working in Kaohsiung, raises issues about patriarchy in Taiwan, gender inequities in traditional Han customs, and women's labor. The course relied on guided class discussions and focus-group discussions, culminating in a visit to the site. Face to face with the researched, the author not only built an inclusive and supportive relationship with students in the classroom, but also put her researcher's reflexivity into teaching practice. Research results indicate that the freedom of the class discussion format succeeded in breaking down the logic of binary opposition that accompanies the traditional gender duality of male/female. Avoiding a top-down teaching style also minimized students' resistance to perspectives emphasizing gender equality.     

Delivering Microfinance in Developing Countries: Controversies and Policy Perspectives

The article reviews three major controversies in the microfinance field: vehicles, technologies, and performance assessments for financial service delivery. Then it proposes that these controversies be resolved by a perspective emphasizing institutional plurality and external and internal efficiencies for individual programs. Questions for further research are discussed in the conclusion.

Diagenesis and elemental geochemistry under varying reservoir oil saturation in the Junggar Basin of NW China: implication for differentiating hydrocarbon‐bearing horizons

In this paper, we attempt to differentiate hydrocarbon‐bearing reservoir horizons of the Junggar Basin of NW China based on the characteristics of diagenesis and associated elemental geochemistry. Reservoirs at this site have varying levels of oil saturation that correlate with the degree of dissolution in minerals (e.g., calcite and feldspar). Four different horizons with varying diagenetic mineral assemblages were observed, including (i) kaolinite‐rich, oil‐dominated horizons, (ii) kaolinite–pyrite–hematite‐rich, oil–water‐dominated horizons, (iii) siderite–chlorite‐rich, water‐dominated horizons, and (iv) chlorite‐rich horizons with negligible hydrocarbon production. The mean MnO content of the representative diagenetic mineral (e.g., calcite) in each of the above horizons is >2.5, 2.0–2.5, 1.5–2.0, and <1.0 wt%, respectively. We propose that the above methodology can be used for the identification of reservoir hydrocarbon‐bearing horizons. We argue that the indicators presented here can be applied in oil exploration across the Junggar Basin.
