Abstract:
The paper discussed the collaborative design standard based on Industry Foundation Class (IFC). It was found that the collaborative design standard should be based on an open industrial standard instead of any private standard. IFC is the available open standard for the building industry. However the IFC open data standard is a necessary condition for the collaborative design standard but not a sufficient condition. It was pointed out in the paper that the process of the collaborative design need also clearly defined in the standard. The paper also introduced the Information Delivery Manual, a use case based methodology to analyze the design process, and Model View Definition, a programmer view of the data exchange within the process. This article points out, based on the IFC data standard framework, the collaborative design standard should include three aspect, namely, IFC data structure, information delivery manual, and model view definition.

Abstract:
As one of the most important stages in a project lifecycle, the construction stage consumes vast quantities of resources and energy and has become a control point for the low-carbon construction. The international stage of carbon footprint evaluation standard has been used in this paper for defining the carbon source in construction stage. A carbon consumption method based on BIM and other related software has been put forward firstly, along with the detailed calculation procedure which holds an important reference meaning to guide the low-carbon construction.

Abstract:
In view of status that the new circular hybrid Steel-Concrete-CFRP-Concrete column (simply called SCCC columns) which was proposed by some scholars nearly tow years, hasn't made a deep research in seismic performance. In this paper, using finite element software ABAQUS simulate seismic behaviors of SCCC composite columns which under the action of axial compressive force and low cycle reversed loading, studied the effect on seismic performance of composite columns in different diameter CFRP tubes. Analysis results show that, along with the increase of CFRP tube diameter, the seismic performance of composite columns had different degrees of improvement. But see from the structure's fire behavior, the increse of CFRP tube diameter will make fire resistance time decreased obviously. Therefore, it is necessary to determine a suitable diameter scope, makes the composite column can play its performance. At the same time, can provide effective theoretical analysis method for experimental.

Abstract:
Single element mesh shape evaluate index of ANSYS and SAP2000 is analyzed and summarized in the present paper.Based on this indexes, a new index is proposed. Benefit from the new index, not only single element mesh but also mesh compose of more elements can be evaluated. A cantilever beam problem is meshed by different shape and procedure programmed by C++ language is used to calculate this index of the mesh, after compared the solution with exact one, a conclusion can be draw that there is a strong correlation between the index value and the precision of solution. Multilayer and high-rise buildings mesh is also evaluated, the results show the index is still efficient and reliable.

Abstract:
Brief discussion on design principles of over-limit frame-supported structure. Through analyzing the deign process, we endeavor to illustrate that for relatively complex structure system, due to the lack of clear specifications or normal requirements from current design codes, need to back to the basic deign principles of structural design. Firstly, need to set the fortification level of seismic deign, under the small, medium and great earthquake respectively, for different parts of the structure and under different forces. Then proceeding with purposive structural analysis, base on the different anticipations and acquiring the corresponding and reliable internal force values. This way, the actually structural status can be reflected and finally secure the safety of the structure.
