For line load calculation of transmission tower structure

there are some similarities between European-American standards and Chinese standards

but there are also great differences between them. As a result

the design software based on Chinese standards is not applicable for foreign projects

which reduces the design efficiency. For far

there is no general software for load combination based on European-American standards available in electric power industry. Firstly

the similarities and differences are analyzed and discussed

and the research results of the related software are referred. And then

based on these

an efficient visual operating program system aimed to realize line load combination calculation of transmission tower based on European-American standards is developed by VB. NET program. The principle and the structure of the proposed program are introduced in detail as well as the key technology of the program. At last

an example is demonstrated

hoping to provide some help for foreign engineering design.
