Bending Capacity of T Beam with Prestressed Concrete-Filled Steel Tube
The prestressed composite T beam with concrete-filled steel tube is made through welding with half I-beam to connect the concrete-filled circular steel tube. The prestressed reinforcement was equipped on the T-beam. The load-bearing capacity and rigidity of the composite beam was enhanced by using prestressed force. In consideration of applying prestress, the corresponding parts stress and strain from the beginning of applying prestress to the phase of elimination of the pressure is calculated through the process of applying prestress; establish the equation of elastic flexural capacity with different location of neutral axis according to the theoretical analyses. Also use the superposition method to build the equation of the deflection. The computational results show that applying prestress reduces the deformation of the composite structure and the mechanic performance has improved which provide important theoretical basis with practical application in engineering.
