英文摘要：

The bending rigidity behavior of full-size detachable formwork with steel bar trusses were tested under monotonic load.The deformation feature of the steel bar truss formwork system during construction phase was obtained as well as the failure modes of detachable formwork with steel bar trusses during service phase.The influences of diameter of reinforcement on the rigidity behavior of composite slab were investigated.Meanwhile,the bending rigidity were analyzed as well as suitable calculation methods and formula of bending rigidity of detachable formwork with steel bar trusses was proposed during different phase.
