In the paper,based on the analysis of practical examples for the long span reinforced concrete slab-wall composite storey beams of a project to point out the problems according to the design of the primary structural member in the action of the vertical loads.

However,the occurence of the D-composite beam gives a light and strong confidence to th.

Nonlinear dynamic response for composite laminated beam with delamination under considering the effect of contact

It is significant to study the numerical simulation method of the flexural failure process of laminated beams reinforced with woven fabric.

In this paper,bending failure experiments have been carried out for five groups of laminated beams reinforced with unidirectional woven fabrics.

Analysis on contact damage problem of composite beam;

The nonlinear contact problem of composite beams is linearized by an inverse method, that is to say, the loading distribution on the contact zone with the adjustable parameter and the contact width are assumed to be given and the curvature of the cylinder is to be solved.

The vibration of a composite beam, embedded with piezo-electric film, is analysed in the paper, Hamilton principle is made in use to analyse the coupled effect between piezo-elec-tricity and structure deformation,considering the influence of electric field on deformation, the e-quation of motion of a composite beam is derived.
