Flexible photovoltaic brackets are gradually being widely used in fishery photovoltaic complementary projects due to their large span

few piles

and large adjustment space for ground height. With the increase of project scale

the length and width of a single flexible array can reach several hundred meters. This article models flexible supports with different spans and analyzes their stress changes. The results show that when the number of spans calculated for continuous spans reaches 6

the error of each cable force is within 5% compared to the entire array

which can be used for approximate substitution calculation. However

the cable forces of the reverse arch cable and transverse diagonal cable vary greatly with the number of spans

and the number of spans cannot be approximated as a substitute for calculation. This study can provide reference for the approximate design of flexible supports with multiple rows and spans in the future

reducing computational workload.
