The safety appraisal of the sluice includes safety check on site and calculation. The safety coefficient of the yellow river sluice is high which indicates significant importance. The traditional structure safety calculation models of frame structure are two dimensional. In this passage three dimensions models of the sluice frame structure was built with finite element analysis software ETABS to analysis the ratio of reinforcement, combined with safety check on site, using shaking type table theory of decomposition reaction method. Compared with the original design, the posts can’t fulfill the requests for fortification against earthquakes. The frame structure should be reinforced.

In early China there was no widespread tradition of making figurines until about the mid-first millennium bc when human figurines started to be placed in burials to accompany the deceased into the afterlife. In prior millennia only pockets of China had seen the emergence of figurines, but these appeared to be short-lived phenomena clearly rooted and linked to local and regional cultures. The overall paucity of three-dimensional imagery and relative rarity of human representations both in two and three dimensions meant that China does not feature in surveys of early figurines. This chapter surveys and discusses selected appearance of figurines of the Neolithic and Bronze Age, with an emphasis on the Hongshan Culture in the northeast, the Yellow River and the Shijiahe Culture along the middle Yangtze.

Strengthening Method

In this paper, the typical deterioration of Northern Approach of Binzhou Yellow River Bridge is reviewed and the method of strengthening is proposed. Based on the theory of grillage method, T-beam grillage is modeled using finite element analysis software Midas civil to study the dynamic behavior of North approach’s superstructure after strengthening. Concerns about integrity of the carrying capacity and overall safety of the bridge are raised. Load simulation tests were performed to evaluate the effectiveness of the method and investigate its effect on structural behavior. And the results indicated that the bridge after strengthening could meet the demanding of intensity and rigidity.

The Impact

In the service of sliding isolated structure, the slip component damage degree determines the safety of sliding isolated structure. The seismic response analysis about a sliding isolated frame structures was obtained by the finite element analysis software SAP2000 at various loads and compared with the traditional structure. Seismic response differences between slip component of the different forms and number damage was studied. According to Teflon invalid and the displacement-limited of energy dissipation component invalid, the impact of seismic response owing to slip component damage was analyzed. It will provide a reference for the isolated building design, the effective maintenance and damage detection.

Based on the mechanics characteristics of the viscoelastic dampers, the seismic performance of a 5 layers steel frame structure with viscoelastic dampers or not was researched. In under the action of the rarely met earthquake, the finite element analysis software MIDAS was used to analyses two of the models of displacements, interlayer shear and ductility of structure. The results showed that: after the installation of viscoelastic dampers, the displacements and interlayer shear of the structure reduced significantly, and ductility increases, the earthquake response can be cut down obviously, it shows better seismic performance.
