technical field [0001] The invention relates to the technical field of steel structure performance analysis, and relates to a method, equipment and computer storage medium for analyzing the performance of building steel structures based on BIM technology. Background technique [0002] In recent years, the experience and lessons of destructive earthquake damage in major urban areas show that most of the steel structure buildings in my country have high earthquake vulnerability. Therefore, analyzing the seismic performance of building steel structures and carrying out reasonable seismic reinforcement can minimize the loss of earthquake damage and protect the safety of people's lives and property.

Problems solved by technology

[0004] 1. The existing methods for monitoring the seismic performance of building steel structures mainly use various types of sensors and monitoring equipment to monitor the connection nodes of steel structures in real time, and manually estimate the seismic performance of building steel structures, so the monitoring period is too long. The steel structure of the building is in a stable state for a long time, which affects the monitoring effect of the seismic performance, thereby reducing the accuracy and reliability of the prediction results of the seismic performance of the steel structure building;

[0005] 2. The existing methods for monitoring the seismic performance of building steel structures basically use artificial estimation methods, which cannot accurately analyze the impact of earthquakes of various levels on steel structures, resulting in differences in the estimated deformation degrees of building steel structure connection nodes, resulting in It is impossible to carry out reasonable anti-seismic reinforcement of the connection nodes of the steel structure of the building in advance, which will increase the earthquake damage loss of the steel structure building and pose a serious threat to the safety of people's lives and property;
