Embodiment Construction
[0019] The present invention will be further described below in conjunction with the accompanying drawings.
[0020] A method for predicting the crashworthiness of reinforced concrete members based on machine learning of the present invention comprises the following steps:
[0021] (1) The establishment of impact database. Through data investigation and statistics, model test and finite element numerical simulation, etc., the specific impact test parameters (impact mass, impact velocity) and member characteristic parameters (member Size, concrete strength, reinforcement ratio, hoop ratio) after impact static performance index (stiffness, ultimate bearing capacity), to obtain component impact test data, impact test parameters and component characteristic parameters as input parameters, the remaining after impact Stiffness and residual bearing capacity are used as output parameters, and the data set θ=[θ 1 , θ 2 ,...,θ N ]=[(X 1 , Y 1 ,Z 1 ), (X 2 , Y 2 ,Z 2 ),…, (X N...
