Cai analyzed and summed up various forms of the “One-step momentum distribution method” in general rigid structureanalysis conventionally used and forwarded a more simplified and practical method. Meanwhile, he proposed the I0/I chart rectangular area method for calculating the beams and columns of varying cross-sections to calculate the deflection constants. In the respect of rigid structure using the main beam as the grid formation, he adopted two simplified and practical criteria, the co.umn top momentum action and the grid formation spanning effect, to conduct the calculation concisely following the general rigid structure analysis, achieving results as precise as those of the minimum work method and redundant force method.

He became Member of the Chinese Academy of Sciences in 1955.
