Integrated Finite Strip Computation for Modelling and Frequency Analysis of Hybrid Laminated FRP Structures

This paper proposes an efficient numerical technique for simulating hybrid fiber-reinforced polymer (FRP) bridge systems. An integrated finite strip method (IFSM) is proposed to evaluate the free vibration performance of cable-stayed FRP bridges. The structural ultra-long span (ULSCSB) totally different than steel and concrete structures due complexity mechanical behavior deck. Herein, anisotropic nature laminated deck considered in analysis by introducing so-called laminate spline strips solution. interactions between all components can be handled using method. Column cable are introduced used model towers cables, respectively. In addition, a straightforward scheme modeling boundary conditions developed. A case study presented through which accuracy efficiency IFSM such structures, as well performing natural frequency long-span bridges, evaluated. results verified against element analysis, significant enhancement terms reduction computational cost demonstrated with same level accuracy.
