Abstract:
In recent years, BIM technology has been widely used in various engineering areas. The bases of BIM technology are the data standards, and the only way to achieve the goal of sharing information is data standards.The mainstream of BIM data standard is the IFC standard, and this paper draws lessons from foreign experiences in IFC standards as well as the research on IFC standard to define the model view of tunnel engineering construction model and investment analysis model, schedule analysis model and the security analysis model. It provides the basis for the final information sharing in BIM-5D management platform.

Abstract:
Current BIM software for structure design is just a simple copy of the original design process. And it doesn't improve the working efficiency. In the age of BIM, the main value of disciplines' cooperation is how to obtain other disciplines'data automatically and efficiently. Through the research on Structural Auto-Calculate-Load-System based on BIM, the author puts forward the following viewpoints: it can improve cooperation efficiency greatly by setting data pre-process module at data exchanging in different disciplines. Furthermore, the pre-process module can reduce the dimension of data exchanging automatically and make auto-identification possible. In summary, it improves the level of BIM application in structure design.

Abstract:
With the rapid development of BIM in China, the application of BIM in the field of architecture is more and more important, and it comes to affect working methods of construction workers, especially the analysis on green energy-saving. The traditional work method is to build models in different green analysis software based on different analysis contents, which is not only time-consuming but also difficult to guarantee the consistency of the models. At present, we can use BIM technology to achieve docking technology between BIM and green analysis software, which can improve the work quality and efficiency. With the Chengchuang Building located in Nanhai District Foshan City as an example, this article puts forward the idea of BIM-based green energy analysis and introduces in detail some key issues like model simplification, format conversion and analysis method according to different analysis content and green model analysis software. The practice results show that the analysis of green energy based on BIM can to a certain extent reduce duplication of modeling workload, guarantee the consistency analysis model and design model, and provide a new technical way for the green energy saving analysis.

Abstract:
With the "Cloud" technology and the development of the Internet, all kinds of application platforms and end use increase rapidly. It is more difficult for professional users of the Internet to obtain and deal with information, and the cost of design management is increased. The unequal mass information and information access lead to high costs, which restricts the efficiency of the professional use of information. The mature cloud platform for professional users of information has professional and efficient features. It can improve the overall level of the information utilization of the design staff through certain technical means and process modes, make the design more convenient, and reduce the cost of the design management.

Abstract:
Transportation management staff not only need to develop a reasonable program of maintenance in the tunnel after the occurrence of defects, but also need to analyze them in order to constantly improve the daily operation and maintenance plan. However, due to complex interactions and dependency of the tunnel components, , the difficulty of defect analysis increased. Building Information Model (BIM) can realize the integration of all information during the whole life cycle of buildings and thus can make this work come true. In this paper, we combine the tunnel monitoring and maintenance data with BIM data base, using the method of spatio-temporal data mining technology and high-dimensional space-time correlation to analyze the relationship between various components and defects. Finally, the paper evaluates the causes and risk levels and works out decision-making plan. All assets and monitoring information create user-defined visualization and interactive interface guides transportation management personnel to carry out tunnel maintenance with innovative thinking.

Abstract:
This paper takes closed-loop building life cycle as bases to discuss the possibility and direction of utilizing as-built data and quantifying BIM data, so that BIM projects of different scales and composition could be cross-compared in function, category, usage condition and so on. Cloud-based computing is an effective way to establish and proceed such multi-layered and process-demanding tasks. The use of cloud-based computing with BIM is also studied. With cross-comparison of BIM projects, evidence-based design and construction would be plausible and BIM as-built data would be better attended.

Abstract:
To make up for the deficiencies of Rayleigh damping and "simplified" modal damping in explicit dynamic analysis, this paper proposes the "correction" modal damping (M-M D) of modal damping and mass damping based on high-precision finite element model. It also analyzes Rayleigh damping and M-M D from the perspective of explicit solving accuracy, stability and inhibiting effect on high-order modal amplifier response. The paper uses PKPM-SAUSAGE to compare the explicit dynamic time calculation results of these two dampings and analyzes the effect of high-order modal amplifier response on structural dynamic analysis and the inhibiting effect of these two damping models on high-order modal amplifier response. The results show that M-M D excels.
