Abstract:
Based on the structural characteristics that the distribution of mass and stiffness was symmetrical in staggered truss structure, the load-carrying performance of staggered truss structure was equivalent to a pressure-bend combinational strut. Through the relationship analysis of curvatures and bending moments and shear forces of the pressure-bend combinational strut, balance differential equation of the pressure-bend combinational strut was erected. Based on Runge-Kutta method, the iteration calculation formula of lateral displacement of story was derived considering the influence of second-order effects. Authors analyzed the lateral displacements of story of staggered truss structure examples in the conditions of considering second-order effects or not, and gave a comparative analysis with finite element software ANSYS. Results show that the calculation method of second-order effect proposed in the paper has a good precision.
