AI Technical Summary

Technical Problem

The design of damper placement in existing frame structures relies heavily on engineers' experience, lacks automated design processes, is inefficient, and makes it difficult to optimize performance indicators such as the number of dampers, their placement, and structural eccentricity. Novices also find it difficult to quickly acquire design experience.

Method used

An incremental allocation and conditional generation model is adopted. By acquiring structural parameters and design drawings, and utilizing DXF drawing semanticization and conditional generation model, the damper layout design drawings are automatically drawn. This includes identifying key elements, generating semantic images, training and evaluating the conditional generation model, and finally automatically generating the damper layout design drawings.

Benefits of technology

It achieves full automation of damper placement, reduces manual operation, determines the number of dampers based on the principle of maximizing vibration reduction benefits, ensures vibration reduction effect and economy, and is easy to integrate with structural analysis software and CAD software, improving the universality of engineering projects.

Abstract

The application discloses a framework structure damper arrangement method based on an incremental distribution and a condition generation model. The method is as follows: obtaining a structure analysis model, damper performance parameters, a seismic record, building design drawings and structure design drawings; based on the maximum seismic reduction benefit principle, determining the number of dampers on each floor by incremental distribution until the seismic reduction target is met; extracting, judging and converting key elements in the building design drawings, and filling and processing the key elements with different colors to obtain a building semantic image to be input; inputting the number of dampers on each floor and the building semantic image to be input into a pre-trained damper condition generation model to generate a damper arrangement semantic image; and automatically drawing the damper arrangement to the structure design drawings according to the generated damper arrangement semantic image. The application significantly improves the design efficiency of the framework structure damper arrangement.
