摘要： A rollover protective structure (ROPS) for use with construction machinery includes a two-post frame having upright posts attached between a base and canopy and cross members attached between the posts. The posts are constructed from a pair of angled post members to define a box-like cross-section for the posts. The posts have rounded interior corners and square interior corners between adjacent sides thereof. Reinforcing members are attached between the adjacent sides and across the rounded interior corners to uniformly stiffen the post. Additionally, reinforcing members are attached between the base and upright posts to reinforce the intersection thereof. The reinforcing members include an upper portion attached between the post and base and a lower portion attached between the upper portion and base. The upper portion and the lower portion are constructed to collapse sequentially to maintain resistance to additional load deformation as the rollover protective structure is deformed.

摘要： A system and method for statistically analyzing a structural member design is provided to obtain a probability that the structural design will meet predetermined design criteria. The present invention provides for numerous spreadsheets, interrelated by way of a macro, to performing statistical analysis on a design, wherein one spreadsheet accepts design input variables. The design input variables are then evaluated by a number of recommended design criteria. If the design fails to meet the recommended design criteria, the user can establish the design (e.g., optimize it in one embodiment) using the optimization spreadsheet. The optimization spreadsheet established the structural member design by automatically adjusting various design inputs so that the structural member design satisfies as many design criteria as possible. Once the desired design input values are discovered, a probability spreadsheet uses random data points to calculate the probability that the structural member design will fail to meet the design criteria.
