The traditional concrete structural design uses limit state method to analyze projects based on sections. However, this method is not suitable for complex stress non-linear structural members. The purpose of this paper is to study the structural safety of precast hole-web concrete deep beams and propose feasible analysis methods based on finite element theory. By using virtual simulation calculation method through finite element analysis software, this paper will analyze the application of Strut ＆ Tie modelling method in structural design of precast hole-web concrete deep beams. This paper will also discuss the application of Strut ＆ Tie modelling method in structural safety analysis by using some precast hole-web concrete deep beam project cases and use Strut ＆ Tie modelling method to calculate the internal force of precast hole-web concrete deep beam to solve practical engineering problems. Eventually, a feasible design method for precast hole-web concrete deep beams will be concluded.
