Abstract:
There are many drawbacks in the present modeling of the grid structure in Revit.Due to the excessive number of components, the conventional modeling is heavy in workload and difficult in to check the errors and to modify them. Applying the volume modeling can be in speed, but the overall model is not accurate enough, and the component parameters cannot be set separately.In order to improve the design efficiency and the modeling accuracy, this paper uses Microsoft's visual studio 2015 development platform for a secondary development of Revit to prepare a grid automation modeling program.This program can generate the Revit model of the welded spherical joints grid quickly, easily and accurately, through reading the LOG text to load the welded hollow sphere joint family and the member family.This program is suitable for the non-curved standard grid of welded spherical joints.The generated grid structure can be modified by the size of the corresponding components according to the LOG text.The overall size of the grid structure is in accordance with the actual situation, which greatly reduces the workload of the design staff.

Abstract:
For the implementation of the building operation and maintenance management on semantic web, a framework for BIM and ontology-based intelligent application is built. Combining some updates with the original DogOnt ontology, a ontology for building operation and maintenance management is created. The methods are proposed to extract information from BIM models for creating individuals and SWRL rules. Proposed framework for BIM and ontology-based intelligent application is implemented by applying the technologies of Revit API, OWL API and SWRL API as Revit built-in programs. The effectiveness of the framework method and programme proposed in this paper are verified by a practical project, and the proposed approach would advance the development of BIM, ontology and semantic web technologies and would be beneficial for networked and intelligent building management of building operation and maintenance.

Panoramic photography is a special imaging technique which has been popular in recent years and has been widely applied. Panoramic photography can be used to generate 360-degree 3D scene images. Direct generation of panoramic camera, such as Ricoh or XiaoMi, is simple in operation but with impressive effect of the image. Just through one shot, the 360-degree 3D images can be generated, with extensive applications of the scene. Introducing the panoramic camera panoramic model, the interactive roaming and the periodic aerial panorama records to the field of construction technology, will bring brand-new visual experience to the construction site management. Many engineering examples have shown that there is large space for the application of panoramic photography technology in the construction engineering.

Abstract:
This paper establishes an ideal model using CFD software by taking the dominant wind direction and speed as the initial condition in Xiamen to simulate the pollutant diffusion range of garbage transfer station. The results shows that the concentration of the odor pollutant was greater than the allowable value in the regional range of sixty meters, which is seen as a basis to guide the general layout. Through establishing an actual model and simulate calculation considering the sensitive building around the garbage transfer station, the result shows that, under the domain wind direction of the summer and winter, some sensitive buildings would be easily polluted, but with small pollutant concentration meeting the regulatory requirements. However, under the static wind of summer, the pollutant concentration of the residential buildings in the northwest and southwest directions would become over the standard requirements, and technical measures should be adopted to reduce the pollutant production of the garbage transfer station. After the adoption, the pollutant concentration of the residential buildings in the northwest and southwest reduces significantly, and meets the regulatory requirements.
