Theoretical analysis and experimental research of laminated beam

In order to accurately analyze the differences on load carrying ability among laminated beam,laminated beam with wedges and beam as a whole of the same dimension,this paper sets up a model of flection of laminated beams with rectangular cross section by taking advantage of Winkle s foundation assumption method and electric testing technique.

Calculation formulas for stress of laminated beam under bending experiment

A composite laminated beam is considered to be in a state of plane stress,the analytical solutions of frequencies and modal functions of a composite orthogonal and anisotropic laminated beam with simply-supported boundary condition are obtained by elasticity theory.

Based on generalizing the structure characteristics of bridge asphalt pavement,the laminated beam model is developed as for bridge asphalt pavement.

The rebuilding scheme fully considers the harmony of the whole bridge with the surrounding environment, meets the planned traffic function requirements and the relative technical standards, puts forward the design of the steel composite beam structure for the main bridge and the technical measures taken for the sunk shaft foundation treat.
