RESEARCH ON DEFLECTION CALCULATION OF COMPOSITE BEAMS WITHOUT BRACING
The deflection calculation of composite beam without support construction and pouring floor slab should be considered in two stages.The dead weight of wet concrete and steel beams can only be considered when pouring floor slabs.When the floor achieves the design strength,the stiffness of composite beams can meet the requirements of the code under the dead load and service load of the building surface.The current code for design of composite structures does not mention the working conditions of deflection calculation in the construction stage.This condition is also not taken into account by common calculation software.The calculated deflection of the composite beam is smaller than the actual deflection.
