    Thesis AI-based prediction of seismic time-history responses of RC frame structures considering varied structural parameters has been published in the Journal of Building Engineering.

    In this paper, an end-to-end framework for Intelligent Seismic Response Prediction, ISRPnet, is introduced. ISRPnet comprises a structural parameter module for discretizing reinforced concrete frame structures into a series of static features and an encoder-decoder architecture for encoding seismic loads and autoregressively predicting seismic responses. The model is trained on a data set of 16,544 cases generated through validated fibre-based finite element models. ISRPnet achieves promising performance on both frequent and rare earthquakes. ISRPnet rapidly and highly precisely predicts temporal responses for frequent earthquakes. The peak displacement predictions remain accurate for rare earthquakes. The superiority of the physical loss and the advantages of gated recurrent unit over long short-term memory are analysed in comparative experiments. Verification with unseen seismic waves beyond the training data shows the robust generalization and extrapolation capabilities of the framework. The proposed model accomplishes efficient surrogate computation of the full-process seismic response for a class of RC frame structures.

    "Development of CAE courses for civil and architectural engineering to cultivate strong cross-disciplinary talents in the new era" has been first published on the China National Knowledge Network in the Journal of Architectural Education in Institutions of Higher Learning.

    In the current rapidly developing economic and technological environment, the civil and architectural engineering industry is facing new challenges and opportunities. To meet the demands of the new era, cultivating talents with interdisciplinary knowledge and comprehensive abilities has become an important direction for education reform in this industry. Based on an analysis of the demand for talents in the new era of civil engineering and architecture, this article explores how to cultivate strong cross-disciplinary talents through the construction of computer-aided engineering (CAE) courses and summarizes the basic experience of CAE course for civil and architectural engineering construction and reform.

    The citation count of "A self-learning dynamic path planning method for evacuation in large public buildings based on neural networks" on Google Scholar is 100. 

    Evacuation path planning is of significant importance to safely and efficiently evacuate occupants inside public buildings. Current computer simulation methods carry out evacuation analysis and then provide emergency education and management with a vivid virtual environment. However, efficient evacuation path planning approaches for evacuation guidance still meet the challenges of generating the analysis models, and lacking of real-time analysis methods under dynamic circumstances. In this study, a dynamic path planning approach based on neural networks is proposed for evacuation planning in large public buildings. First, an automatic process to develop the evacuation analysis model with simplified but sufficient information is presented. Then a path generation algorithm is proposed, together with an evaluation process, to generate a number of training sets for policy neural networks. When the primary policy neural network is preliminarily trained, it falls into a self-learning iteration process. Finally, the approach embeds a dynamic algorithm to simulate the mutual influences among all occupants in the building. The neural network was trained according to a real large public building and then the approach managed to provide rapid and feasible evacuation guidance for both occupants to escape in multiple scenarios and managers to design the evacuation strategy. Test results showed that the proposed approach runs 8–10 times faster than existing software and traditional search algorithms.
