Take one long span double-curved arch bridge as the example, built the finite element model of bridge structure and analyzed the modeling method, dynamic features and response under ground motion. It demonstrates that response spectrum method could meet the calculation requirement in seismic analysis of the double-curved arch bridge, and the result accords with time-history analysis method. Bridge vibration type is dispersing in quality distribution of double-curved arch bridge; it should take adequate vibration types in bridge combination. At frequent earthquake, it is actual to considerate the coalition function between arch crown structure and the main arch ring. But at rare earthquake, the arch crown buildings of masonry structure is easy to be damaged, it is not suitable to considerate the coalition function in bridge reinforcement.

According to Japan Railway seismic design code, truss finite element model is established considering the pile components and foundation nonlinear finite element model in this paper, an analysis on the ultimate horizontal bearing capacity of bridge pile foundation of passenger dedicated line is made and the results of m-method calculation are compared. The analysis results show that: when horizontal force at the top of pier is larger, with the pile side soil horizontal and vertical force continuously into the plastic, the calculation results differ greatly with two seismic specification; the pier top level force-displacement skeleton curve considered pile-soil interaction is available in trilinear description, the analysis results can provide a theoretical basis for the seismic analysis of the pile foundation under rare earthquake.

L-shaped plane structure in the common buildings cannot meet seismic requirements because of significant torsion. According to the analysis of the vibration characteristics, structural deformation and base shear of irregular L-shaped plane structure under frequent and rare earthquake, four arrangement plans of viscous dampers are proposed to adjust the stiffness of the structure. The layout principles of viscous dampers are obtained by comparing effects of different arrangements such as in the periphery, in the short sides, in the long sides and in both short and long sides.

A nonlinear finite element method is used to analyze the dynamic property of a five-storey reinforced concrete (RC) frame structure with and without carbon fiber reinforced plastic (CFRP). When the frame strengthened by CFRP, seismic performance of that is improved better than the frame without CFRP. The inter-story displacement angles of the frames with and without CFRP satisfy the seismic requirements from the results of earthquake transient analyses, when the frame is exposed to the frequent and rare earthquake.

ABSTRACTA review of the educational literature on naive concepts about principles of chemistry and physics and surveys of science museum visitors reveal that people of all ages have robust alternative notions about the nature of atoms, matter, and bonding that persist despite formal science education experiences. Some confusion arises from the profound differences in the way that scientists and the lay public use terms such as materials, metals, liquids, models, function, matter, and bonding. Many models that eloquently articulate arrangements of atoms and molecules to informed scientists are not widely understood by lay people and may promote naive notions among the public. Shifts from one type of atomic model to another and changes in size scales are particularly confusing to learners. People's abilities to describe and understand the properties of materials are largely based on tangible experiences, and much of what students learn in school does not help them interpret their encounters with materials and phenomena in everyday life. Identification of these challenges will help educators better convey the principles of materials science and engineering to students, and will be particularly beneficial in the design of the Materials MicroWorld traveling museum exhibit.

 Inter-storey drift is an important parameter of structural behavior in seismic analysis of buildings. Pounding effect in building simply means collision between adjacent buildings due to earthquake load caused by out of phase vibration of adjacent buildings. There is variation in inter-storey drift of adjacent buildings during pounding case and no pounding case. The main objective of this research was to compare the inter-storey drift of general adjacent RC buildings in pounding and no pounding case. For this study two adjacent RC buildings having same number of stories have been considered. For pounding case analysis there is no gap in between adjacent buildings and for no pounding case analysis there is sufficient distance between adjacent buildings. The model consists of adjacent buildings having 4 and 4 stories but unequal storey height. Both the buildings have same material & sectional properties. Fast non-linear time history analysis was performed by using El-centro earthquake data as ground motion. Adjacent buildings having different overall height were modelled in SAP 2000 v 15 using gap element for pounding case. Finally, analysis was done and inter-storey drift was compared. It was found that in higher building inter-storey drift is greater in no pounding case than in pounding case but in adjacent lower height building the result was reversed. Additionally, it was found that in general residential RC buildings maximum inter-storey drift occurs in 2nd floor.
