Abstract: In this paper, the method and steps for equivalent cross-section of steel-plybamboo deck is established according to the equivalent principles and plane cross-section assumption. And then according to the material mechanics theory, the calculation methods for ultimate load and moment are given. On this basis, the relationship between and limit load, moment of different structures are studied. The results show that in order to meet use requirements, the thickness should be larger than10 mm as in engineering the span of a general board will reach 3 m.
Keywords: steel-plybamboo deck; equivalent principle; limit load
