Research On Capacity Of Corrugated Web Beam With Open Holes

The corrugated webs are used to open the corrugated webs in one or several bands of the web in accordance with the actual engineering requirements so that the various pipes can be made.Do not have another layer of occupation,and from the web directly through.And because there is no corresponding research on the carrying capacity of corrugated webs at domestic and abroad,the specification of this aspect is also lacking in practical design,so this paper puts forward the research on its bearing performance.In the paper,the bearing capacity of corrugated webs in the elastic stage,and compare the bearing capacity of corrugated webs with the bearing capacity of corrugated web beams and honeycomb beams are studied.According to the corrugated webs and the existing.The calculation method of the capacity of corrugated webs is presented.In the paper,the capacity of corrugated corrugated webs and corrugated corrugated webs is studied.The corrugated shapes are selected for the analysis of two ripple parameters.By comparing the influence of the physical parameters such as the centroid of the corrugated web members,the moment of inertia and the cross section resistance moments,the bending and shear calculation formulas of the corrugated webs are obtained.The FEM is used to simulate the multi-component components and compare with the previous experimental data to verify the correctness of the numerical simulation.Then,the FEM is used to analyze the practicability of the above formula,and then the finite element software is used to analyze the factors And the bearing capacity and buckling mode of the corrugated webs under different factors were analyzed.In the paper,the effects of the following factors are studied:web thickness,beam span,ripple type,ripple parameter and porosity.Through the finite element numerical analysis,the application of corrugated web opening beam in practical engineering is put forward.
