it has some technical difficulties, such as weak overall lateral stiffness, poor stability, complex joint structure and great
construction difficulty. Taking this as an example, the overall construction process and construction technology of
beam string structure are summarized. The cable installation, tension sequence and tension process monitoring are
emphasized, which can provide reference for similar projects.K e y w o r d s: prefabricated; wooden; beam string structure; tension g 7 \ > ? , : n ♦ ? ?x ?A ? uZG? x
