Recent research

Constrained Stochastic Imperfection Modal Method

Based on virtual interation forces, the structural topology constraint is considered, and the constrained stochastic imperfection modal method is proposed for single-layer reticulated shells with controllable computational cost and reasonable accuracy. Journal paper

Early-warning Collapse of Planar Steel Trusses

Through parametric analysis, all collapse modes and mechanisms of planar steel truss structures under arbitrary conditions are summarized, and an early-warning method for fire-induced collapse is proposed based on the evolution laws of key physical parameters (joint displacement and displacement velocities). Journal paper

DNN-driven Real-time Displacement Prediction

Based on the measured data of structural fire response and deep LSTM neural networks, the real physical model of the fire-stricken building is identified, and a real-time prediction method for hard-to-measure critical displacement of the building under fire is proposed. Journal paper Codes

Critical Element Identification of Frames

A quantitative approach is proposed for identification of critical element identification of frame structures against progressive collapse, based on deep graph neural networks and reinforcement learning. Click the figure to see the optimized demolition plan for a 4×5 frame. Accepted manuscript

Machine-specified Ground Structure Method

The topology of 2D truss structures can be self-generated using the graph embedding and the policy network. The self-generated topologies are further utilized to generate the machine-specified ground structure, which can be applied to solve topology optimization problems with singular optimal solutions. Click the figure to see the self-generation process of a truss based on a 6×3 node-set. Journal paper
