Improving the design of reinforcing frames by simulating the arch and peltate venation structures

Based on the analyses on arch and peltate venation structures, the design of reinforcing frames was improved. First, distribution rules of the arch structure were summarized. According to the load condition and the structure of the frame, a mechanical model of arch structure was developed, and two solutions for the model were analyzed and compared with each other. Through the analysis, application rules of arch structure for improving the design were obtained. Then, distribution rules of peltate venation structure were summarized. By using the same method, application rules of peltate venation structure for improving the design were also obtained. Finally, mechanical problem of the frame was described, and rib arrangement of the frame was redesigned. A parameter optimization for the widths of ribs in bionic arrangement was also carried out to accomplish the improving design. Comparison between bionic and conventional reinforcing frames shows that the weight is reduced by as much as 15.3%.
