Seismic analysis

In this paper, a two-step method based on the superposition theorem is used to perform a seismic analysis of a soil-foundation-tank-liquid system (soil-liquid tank system). The SFI analysis was conducted in the first step using the CyclicTP program's finite-element method.

The seismic performance of isolators for bridges in a typical earthquake area in Vietnam is preliminarily investigated based on an analysis of a simplified isolated-basebridge model. The obtained results allow for providing fundamental research products and a more in-depth and comprehensive understanding of the base isolation application for bridges, toward practical application in Vietnam.

This study presents some research results on the relationship between the geological environment of the surface layer and the level of modern tectonic activity in the sea waters of the Hoi An - Cua Dai area based on the interpretation of high-resolution shallow seismic data combined with the surface sediments’ grainsize analysis and other available data sources. The results show that the surface geological environment in the coastal waters North of the Thu Bon river fault is influenced by modern tectonic activities, believed to be a part of causing geological catastrophic events.

Depositional environments in areas located near sea level are vulnerable to even subtle changes in both tectonism, climate and eustatic sea level. Sorting out mechanisms behind depositional changes in inner shelf-margins and epeiric seas is therefore far from straight forward. The epeiric Malay-Tho Chu Basin, located in the shallow Gulf of Thailand offshore Vietnam, contains a thick uppermost Oligocene to Recent post-rift succession.

In this paper, we considered the propagation wave in transversely isotropic piezoelastic medium based on the nonlocal strain gradient theory. Two kinds of scale parameters, namely, the nonlocal parameter and the strain gradient parameter are introduced to account for the size effect of mechanical properties of nanostructures.

In this study, in order to investigate the error rate of seismic analysis methods (static equivalent, spectral and time history) in intermediate structures with irregularity of hardness, 4 5-story steel samples with dual flexural frame system and bracing with different states of irregularity in height in soft SAP software has been modeled. The results showed that the equivalent static analysis method always provides conservative and somewhat uneconomical values compared to other methods, so it can be said that for static buildings, equivalent static analysis is reliable.
