The dimensional design result of the building structural member embedded with the domain knowledge is very close to the design result of an engineer and meets the domain knowledge. A comparison of the building structural member dimensional design embedded with domain knowledge and the engineer's design in terms of material usage and time consumption is shown in table 5. In terms of concrete usage, the building structure member size design embedding domain knowledge uses 3.18% less on frame columns, 1.28% less on shear walls, and 2.06% less on the total of the two, compared to the engineer's design. It can be seen that the building structural member dimensioning embedded with domain knowledge is more material-saving. Furthermore, a skilled engineer typically takes more than 30 minutes to design a cross-sectional dimension once, whereas a building structural member incorporating domain knowledge typically takes only 12 seconds to design a cross-sectional dimension, which increases efficiency by 150 times.
