The embodiment of the invention relates to the technical field of intelligent building design, and discloses a building structure steel bar layer design method and device, electronic equipment and a medium. The method comprises the following steps of receiving input building design information in a building structure design model, acquiring data information of the building structure design model according to the building structure design model, wherein the data information comprises a model standard layer, a natural layer, a steel bar standard layer, and building design information and structural member information related to the standard layer, the natural layer and the steel bar standard layer, according to the model standard layer and the natural layer, splitting a steel bar standard layer, and acquiring at least one steel bar layer corresponding to the model standard layer, obtaining the steel bar content of each steel bar layer in the model standard layer, and according to the steel bar content of each steel bar layer, combining the steel bar layers according to a combination strategy, and acquiring a standard layer. According to the method, the steel bar layers in the structure model are automatically split and combined, manual splitting and combining are not needed, automatic model processing is achieved, therefore, the design working hours are saved, and the construction cost is reduced.
