Uniform design (UD) method is one of the findings of number theory. UD has widely application scopes in traditional experimental design and compound design. Some newly developed applications by our team to civil engineering are introduced. These cases include experimental design of concrete corrosion by sulfuric acid, structural damage detection, calculation of response spectrum for stochastic pedestrian loads and reliability calculation of foundation pit and compartment fire. A nonparametric regression method, alternating conditional expectation (ACE), is also introduced to analyze the datum from UD in some cases. The results show that the UD is efficient and applicable in addressing many related problems in civil engineering since it can decrease the required number of experiments remarkably for both physical experiment and numerical experiment and cut down expense, calculation work and time. Therefore, the UD can be adopted to solve similar problems in the fields of civil engineering and other.
