Deformation calculation formulas of prestressed steel-Concrete-Steel sandwich panel

Steel-Concrete-steel sandwich panel is a new tape composite plates, in which the two steel plates are inter-connected by a series of transverse bar connectors simultaneously friction welded at both ends or only one end, the load-bearing capacity and the rigidity of sandwich panel will be enhanced by using prestressed force. The interface slip of prestressed steel-concrete-steel sandwich panel appears to a certainty under the external load, which induced internal force redistribution between concrete plate and steel plates. According to the structure characteristics of sandwich panel, the deformation differential equations that considering the effect of interface slip were established based on elasticity theory, the deformation calculation formulas of steel concrete steel sandwich panel were presented by the relationship between slip and deformation.
