Based on the principle of energy, this paper derives the general method of lateral force analysis of rib-arch bridges under vertical loads, which can be applied in engineering design. I. INTRODUCTION In recent years, in the design of arch bridges, the importance of the horizontal distribution of loads has drawn increasing attention from bridge workers. Many researches have been conducted in this area, and some calculation methods for the lateral distribution of loads on arch bridges have been proposed. . However, some of these methods are limited to the limitations of the method or some objective factors, resulting in a certain degree of promotion and application in engineering design.
