Modeling and calculation of shear capacity of prestressed high strength concrete beams with web reinforcement based on BIM

To improve the accuracy of predicting the shear bearing capacity of prestressed high-strength concrete beams with web reinforcement, shorten the prediction time, and improve the quality of engineering construction, a BIM model is proposed to predict the shear bearing capacity of prestressed high-strength concrete beams with web reinforcement. For the first time, specimens of prestressed high-strength concrete beams with web reinforcement were made, and their mechanical performance parameters, test points, and loading schemes were determined; Secondly, use the MCT file in Midas Civil to create a finite element model, and then combine the revit parameter model method to establish a BIM based finite element model; Finally, through the data conversion program between the created Revit model and ANSYS, a BIM based mechanical analysis model is generated to predict the shear bearing capacity of prestressed high-strength concrete beams with web reinforcement. The results show that this method can obtain high-quality three-dimensional renderings, with a standard deviation of 0.118 between the predicted shear bearing capacity and the experimental value, and a prediction time of about 0.5 s, which is lower than the expected results. This method has high prediction accuracy and efficiency, which can provide reliable technical reference for construction projects and improve the safety of building structures. (c) 2023 THE AUTHORS.
