BIM-Based Automation Process for Seismic Detailed Assessment of Reinforced Concrete Building Structure

This paper proposes an automation process for BIM-Based detailed seismic assessment of buildings based on BIM, from the structural engineering point of view. The current building seismic assessment tasks must be performed by architects, civil engineers, or structural technicians. It is not easy to manage drawings and models, especially when the original as-built drawings or structural design drawing information is entered incorrectly by humans, it is even more difficult to check errors. It is a pity that the structural analysis model used in the assessment of reinforcement has not been converted into a building information model, and cannot be used for subsequent operation and maintenance management. Therefore, this research develops automated processes and attempts to integrate the functions expected by architects, technicians and owners. First, establish the building model information model, and obtain the main parameters of seismic evaluation analysis through the self-developed interface processing program, and then export it to the structural analysis program. Finally, assigning the plastic hinges and carrying out the nonlinear static pushover analysis, the seismic resistance of the building can be quickly and accurately obtained. The building model information model used in this study is TEKLA Structure. The advantage of applying the Tekla Structures is to figure out the beams and column reinforcements by self-developed API programs. The seismic assessment programs are TEASPA and SERCB program, and structural analysis program is ETABS. The text input file exported by TEKLA Structure for TEASPA or SERCB to calculate the properties of plastic hinges will be connected by a program developed by authors. This research finally uses a new-design building and an existing structure to demonstrate the case study. The advantage is that the information is reserved in the TEKLA Structure to facilitate the management and preservation of the data. In addition, the analysis time and the omission of information in the exchange process are reduced, and the earthquake resistance of the building can be quickly and accurately obtained. © 2021, Chinese Institute of Civil and Hydraulic Engineering.
