    Xiaoyang Zhang, the second master student under my supervision, has successfully passed thesis defense entitled "BIM-Based Analysis and Management System for Safety Performance of Time-dependent Structures" in the Department of Civil Engineering of Tsinghua University. His research aims at carrying out automatic structural analysis during construction. Based on the newly developments in Building Information Model (BIM) and 4D technology, a 4D Safety Information Model++ (4DSIM++) is proposed and established for architecture design, structural analysis and construction management. Based on the 4DSIM++, the approach and mechanism are proposed to achieve the model conversion between architecture and structure model automatically and relative analysis among structure analysis models. Then the integrated technologies are discussed on architecture and structure model and different kinds of monitoring data dynamically. Based on this information model, the application workflow and a series of methods for dynamic safety analysis and management are detailed discussed. Finally, a BIM-based Safety Analysis and Management System (BIM-SAMS) for time-dependent structure during construction is developed and the feasibility and effectiveness of the system are verified by real project applications.

    "Key-value cache based IFC model implementation for web environment", the achievements of the research team, has been published in the Journal of Tsinghua University (Science and Technology). The paper describes a web-enabled IFC object model using the JSON format and the IFC data cache with the Redis distributed key-value store for IFC application in web environment. Stepwise and dynamic parsing of the IFC data enables lightweight, standardized network data transmission with large-capacity, high-speed dynamic parsing of the IFC data. The Journal of Tsinghua University (Science and Technology) is one of the core journals of China included in the EI (Engineering Index) database.
