| Abstract: |
| In order to study the relationship between the interfacial slip of double-row stud-combined beams and single-row stud-combined beams,based on the single-row stud-glued wood-concrete theory,the interfacial slip differential equations of double-row as well as multi-row stud-combined beams were established by changing the peg slip constitutive relationship on the interface of single-row stud-combined beams,the analytical solutions of double-row stud-combined beams under the action of the three kinds of loads commonly found in the engineering were solved,the interfacial slip differential equations of triple-row as well as multi-row stud-combined beams were analysed,and the computation method of the bending stiffness of the double-row stud-combined beams was put forward.Conclusion: Although wood is an orthotropically anisotropic material,it is known from the strain relationship and Hooke’s law for interfacial slip in combined beams that the slip at the interface should be related to the modulus of elasticity in the same direction as the force.The main difference between single-row and double-row stud differential equations is that the double-row stud characteristic coefficients are twice as large as the single-row characteristic coefficients.That is,when the double-row peg stiffness K is equivalent to a single-row peg 2K,the bending stiffness that can be equivalent to a single-row peg stiffness is calculated.The errors of the theoretical formulations of slip and flexural stiffness calculations of double-row stud-combination beams with Ansys numerical simulations,respectively,are around 5-6%,which proves the reliability and practicability of the present method for analysing the interfacial slip and flexural stiffness of double-row stud-combination beams. |
