Abstract:
Data exchange between BIM (Building Information Modeling)-based application software and energy simulation tools such as EnergyPlus is a critical problem for developing BIM-based building energy-efficient design software. Although there are several related studies, neither the specific mechanisms nor commercial software have been published. In this paper, through analyzing the IFC (Industry Foundation Classes) standard which is the mainstream standard of BIM data, and the IDF (Input Data File) format which is the input format of a well-accepted software for the analysis, i. e. EnergyPlus, both the IFC-based model of design data and the IDF-based information model for the analysis of building s energy consumption were established. Then the mechanism for transformation from the former to the latter was formulated. Finally the mechanism was implemented by establishing several key algorithms in the application software and verified for a project of building design. It is shown that the established mechanism can improve the efficiency of preparing the model for the analysis significantly. This research lays a solid foundation for the development of BIM-based building energy-efficient design software.

Abstract:
BIM technologies and tools are developed very fast these years, which provide an effective and efficient method to solve the "segment"problem in building industry. However, since data exchange is still mostly based on files, an integrated BIM containing all the information of multi-disciplinary can't be constructed, so that much value of a BIM is hard to achieve. For constructing an integrated BIM, this paper proposes a framework of the modeling technology for integrated BIM, which enables integrating information generated in difference phases dynamically. The framework includes architecture, modeling flows, deployment framework and key technologies needed to be solved. After that, a prototype system of BIM data integration and server platform (BIMDISP, a BIM Server) is developed. Then a real word project is applied in the BIMDISP to test performance of the modeling technology. As a conclusion, the modeling technology proposed is feasible to support integration, management and sharing of all the building information, so as to generate an integrated BIM.

Abstract:
Based on the theory of seepage of groundwater and Terzzaghi's consolidation, this paper discussed a new prediction method combined with in-situ test. The paper introduced the concrete ideas of the new method, and corresponding calculation formulas were deduced too. The related parameters and the distribution laws of ground settlement can be derived from the in-sire pumping tests on wells, based on the relationship between drawdown and surface subsidence derived from the back analysis of the in-sire pumping tests, numerical simulation methods were used to predict the surface subsidence in the field. The results of engineering example showed that the method could better predict the surface settlement caused by dewatering of confined water, which is an effective method to predict the surface settlement.

Abstract:
With the rapid development of urbanization, the house appearance design comes to a new developing period, of which the most rapid development is roof garden. In recent years, as the earthquake disasters happened frequently, in the city the buildings with earthquake resistance property are drawing more and more attention. Combining the roof garden with the earthquake resistance, we use ADINA software to create a model and do some research on earthquake dynamic displacement response. Next, control model and control model calculation results were compared and some meaningful conclusions were displayed.
