The plastic beams are produced using a unique process developed and patented by Lankhorst. Four steel reinforcement bars are integrated and encased within the plastic during the moulding process. Several diameters of plastic i beam steel bars are possible – depending on the application. that the deflections necessary to develop the stresses indicated in a plastic analysis are generally excessive, frequently to the point of incompatibility with the function of the structure. Therefore, separate analysis may be required to ensure design deflection limits are not exceeded. Also, since working materials into the plastic range can lead to permanent deformation of the structure, additional analyses may be required at limit load to ensure no detrimental permanent deformations occur. The large deflections and stiffness changes usually associated with plastic bending can significantly change the internal load distribution, particularly in statically indeterminate beams. The internal load distribution associated with the deformed shape and stiffness should be plastic i beam used for calculations.
Plastic bending occurs when an applied moment causes the outside fibers of a cross-section to exceed the material’s yield strength. Loaded with only a moment, the peak bending stresses occurs at the outside fibers of a cross-section. The cross-section will not yield simultaneously through the section. Rather, outside regions will yield first, redistributing stress and delaying failure beyond what plastic wood would be predicted by elastic analytical methods. The stress distribution from the neutral axis is the same as the shape of the stress-strain curve of the material (this assumes a non-composite plastic i beam cross-section). After a structural member reaches a sufficiently high condition of plastic bending, it acts as a Plastic hinge.
Elementary Elastic Bending theory requires that bending stress varies linearly with distance from the neutral axis, but plastic bending shows a more accurate and complex stress distribution. The yielded areas of plastic i beam the cross-section will vary somewhere between the yield and ultimate strength of the material. In the elastic region of the cross-section, the stress distribution varies linearly from the neutral axis to the beginning plastic i beam of the yielded area. Predicted failure occurs when the stress plastic beams distribution approximates the material’s stress-strain curve. plastic outdoor furniture The largest value being that of the ultimate strength. Not every area of the cross-section will have exceeded the yield strength
