Abstract: An intelligent layout design method of curvilinearly stiffened structure based on image feature learning. Firstly, the design variables of the curvilinearly stiffened structure are determined based on the path function. The autoencoder network is built to complete the learning of the structural characteristics of the image, and the transfer learning of the model is further carried out. The convolution neural network is built to complete the learning of the image set with mechanical response labels. Finally, the evolutionary algorithm is used to optimize the layout of the curvilinearly stiffened structure based on the model. The invention solves the problem that the traditional optimization method is difficult to deal with the optimization design with many and variable design variables, and is expected to become one of the most potential technical means involved in the layout design of components in the engineering field.

Abstract: The present invention belongs to the technical field of energy consumption and vibration reduction of assembled building structures, and provides an energy-consuming connecting device for a prefabricated assembled wall. The present invention provides a normal connection function between walls, and also has the functions of energy consumption and vibration reduction. A used viscoelastic material can provide energy consumption and weaken the cold and hot bridge effect, which is beneficial to building thermal insulation. Meanwhile, the energy-consuming connecting device for the prefabricated assembled wall can be connected with a prefabricated wall in advance, which can be carried out at the same time as the wall is inserted during construction, thereby effectively increasing the construction efficiency. Through the design of clamping groove devices, the wall can be connected firmly and reliably while generating displacement and consuming energy. A multi-segment fixing plate is used to replace full-length arrangement to save the steel.
