Non Destructive

Now, the field experiments according to the non-destructive test method are developing widely in diagnostics and verification of structural engineering. To research and apply the impact vibration test, one of these non-destructive methods, the construction of the design dynamic analysis model is significant. The paper goes into research on the formulas to determine the dynamic spring coefficients according to Japanese and Vietnamese standards. Then, apply calculations for dynamic analysis models of pile foundations built in the Binh Thuan sea area. The impact vibration test in the field shows the appropriate formula for calculating the coefficient of dynamic springs in Binh Thuan, Vietnam.

This paper conducts an analytical research on the use of bridges, and discusses how the vibration of bridges is affected by the healthiness of piers. Meanwhile, Impact Vibration Test Method is introduced, by which the modal parameter of bridges can be tested. A lot of dynamic tests of piers are conducted by using this method. By analyzing data and identifying modal information of piers, this paper made a conclusion on the general law of the impact each parameter has on characteristic frequency of the piers. The bridge finite-elemental model is constructed according to the actual structure of piers, the impact vibration test load stimulated, then computed and analyzed with the dynamic time-history method. Bases on the comparison between test result and frequency of Time-domain transverse velocity received the results of the analyses identify the frequency spectrums, the validity of the Impact Vibration Test Method is verified.

Structural Traits

The Vietnamese Catholic community is not only a religious community but also a traditional village with relationships based on kinship and/or sharing the same residential area, similar economic activities, and religious activities. In this essay, we are interested in examining migrating Catholic communities which were shaped and reshaped within the historical context of Viet Nam war in 1954. They were established after the migration of millions of Catholics from Northern to Southern Viet Nam immediately after Geneva Agreement in 1954. Therefore, by examining the particular structural traits of the emigration Catholic Communities we attempt to reconstruct the reproducing process of village structure based on the communities’ triple structure: kinship structure, governmental structure and religious organization.
