Though the West Baotou Earthquake (Ms6.4) was only an earthquake with medium intensity, it was shown that the seismic resistance of many buildings in old town was low.
According to the vibration test results of Dalinghe bridge,oil pipeline,dampers,and the stability analysis of bridge basement and bank,and seismic resistance calcu-lation,the suggestions for safety of Dalinghe bridge oil pipeline are put forward.
Energy dissipators, isolated-resistant and specific structural forms for earthquake resistance are popular topics in the research to improve shock-resistance.
The paper concludes with a discussion on the relevance of the current codal provisions for earthquake resistance of masonry structures and the direction of further research in the area.
Presented herein is an experimental study on seismic resistance of rectangular steel reinforced concrete (SRC) columns confined with a new type of multi-spiral cage.
Therefore, it is necessary to assess the vulnerability of the bridges and retrofit measures are required to increase the seismic resistance of the bridges.
It was found that a homogeneous idealization of the unbounded foundation may sometimes greatly underestimate the maximum earthquake stress response of the dam.
Therefore, taking into account the effect of foundation inhomogeneity for the earthquake safety assessment of concrete arch and gravity dams has great significance.
The PGA values obtained will be useful for civil engineers, regulators and planners, in order to mitigate the effects of earthquakes and to plan earthquake resistant designs.
