Abstract

This study analyses the spatial variation of the deflection, rotation, and slip at the interface of two-layer bamboo scrimber-concrete composite beam simply supported under uniform transverse load on its entire length. The Timoshenko model is considered, and the equations are solved using the analytical methods and direct numerical simulation based on finite differences schemes and a Fortran code. The results obtained show that it is a good agreement between the results from the mathematical calculation and those obtained from the numerical simulation.

Highlights

  • Composite structures have excellent combined advantages that are increasingly important in different areas of engineering practice, but more widely used in civil engineering

  • E classic cases of such structures in civil engineering are composite steel-concrete beams, composite wood-concrete panels, reinforced concrete in buildings and bridges, woodconcrete floor systems, coupled bracing walls, concrete beams reinforced externally with laminates, sandwich beams, and many others [1,2,3,4,5,6,7,8]. Some advantages of this type of composite structure constituted, for example, by two layers can be seen as easy manufacture, taking advantage of the material properties

  • The dependence of the stress state on the stress history is intrinsic. is study focuses on the mechanical behavior of two-layer beams bonded with adhesives

Summary

Introduction

Composite structures have excellent combined advantages that are increasingly important in different areas of engineering practice, but more widely used in civil engineering. Erefore, an appropriate approximation of the inplane displacements over the thickness of the plate and the incorporation of transverse shear stresses that govern the sliding behavior at the interface are considered to be key elements for the development of accurate theories of beams which can simulate the degradation of the rigidity due to the interlaying slip In this present study, a new analytical method of the twolayer composite beam with two layers with an interlayer slip which takes into account deformations, slips, rotations, and displacements has been developed using the approximate analytical method of the weighted residuals known as the least squares method [40].
