Abstract

The invention relates to a load evaluation method of a roof steel plate structure based on ResNet. The method comprises the following steps that Ansys finite element analysis software is used for conducting finite element simulation on a steel plate structure of a roof, a strain collection position is determined, and strain values corresponding to different loads are obtained; performing data screening and cleaning on the obtained strain values, establishing a roof panel mechanism load-strain database, and dividing a training set and a test set; training the training set data by using ResNet34, and testing in the test set to obtain a test result; and the average relative error is used as an evaluation index. After data preprocessing is completed, the training set is used for training the ResNet34 model, and the model is evaluated on the test set; and then the trained ResNet model is used for load prediction of the roof steel plate structure. According to the method, the roof steel plate structure load is accurately detected, the practicability is high, and the accuracy is higher than that of a traditional load calculation method. The method can be widely applied to the field of roof steel plate structure load calculation.

Description

technical field [0001] The invention relates to the field of roof steel structure load calculation, in particular to a ResNet-based roof steel structure load evaluation method. Background technique [0002] In the process of building roof renovation, the steel plate roof construction method is used as the main construction technology. In the actual process, the increase of roof stiffness can affect the overall stiffness of the structure, ensuring the stability and safety of the structure. However, there are few domestic studies, so it is necessary to carry out finite element overall static analysis of this structure type. Finite element analysis is a necessary means of auxiliary test research today, which can make up for the time-consuming test analysis, limited parameter analysis, and labor-intensive cost. and other shortcomings. [0003] Foreign research on roof steel plates began in the middle of the last century, and plywood was first used as roof panels; by the 1980s,...
