Carrying Capacity Calculation of Externally Prestressed Profiled Steel Sheet Composite Slab
According to the structural features and actual load carrying status of externally prestressed profiled steel sheet composite slab, in consideration of the deformation of the whole prestressed structure, the prestressed incremental calculation formula is established with force method and the prestressed incremental calculation formulas for arranging reinforcements in straight line or fold line with deviators; according to the positions of neutral axis, the stress-strain of externally pre-stressed profiled steel sheet and concrete composite slab section is analyzed so as to derive the calculation formulas for the elasticity bending bearing capacity and ultimate bending bearing capacity of the externally prestressed profiled steel sheet composite slab.
