“…The second substrategy characterizes the optimization problem, and considers constant relative stiffness between roof and columns. This method was previously demonstrated by [30], with constant relative stiffness being enforced during optimization to ensure that the algorithm was solving the equivalent structural system in every iteration. In this study, implementing constant relative stiffness can effectively improve the optimization result, as the columns' axial stiffness can vary throughout optimization to give different structural systems.…”

The roof–column structural system is utilized for many engineering and architectural applications due to its structural efficiency. However, it typically requires column locations to be predetermined, and involves a tedious trial-and-error adjusting process to fulfil both engineering and architectural requirements. Finding efficient column distributions with the aid of computational methods, such as structural optimization, is an ongoing challenge. Existing methods are limited, with continuum methods involving the generation of undesired complex shapes, and discrete methods involving a time-consuming process for optimizing columns’ spatial order. This paper presents a new optimization method to design the distribution of a given number of vertical supporting columns under a roof structure. A computational algorithm was developed on the basis of the optimality-criterion (OC) method to preserve and removed candidate columns pre-embedded with design requirements. Three substrategies are presented to improve optimizer performance. The effectiveness of the new method was validated with a range of roof–column structural models. Treating column locations as design variables provides opportunities to significantly improve structural performance.

“…Compared with the transverse ribs of traditional box girder, the bionic design of bamboo can correspondingly reduce the number of transverse ribs, which could meet the stability requirements, as well as the lightweight requirements, while also meeting the strength and toughness requirements. Zhao et al [134] explored the biomechanical morphology of the leaves and stems of representative emergent plants by combining experimental and numerical methods, and they developed an interdisciplinary topological optimization method that combines mechanical properties and dual ecological constraints. In the two-way evolutionary structure optimization technique, the proposed biophysical insights are expected to be used to design efficient and advanced structures (aircraft wings and turbine blades).…”

In the field of mechanical equipment manufacturing, the focus of research and development is not on weight reduction, but on how to choose between the rigidity and performance of components (such as strength or flexibility). For this contradiction, lightweight is one of the best solutions. The problems associated with lightweight were initially considered and systematically studied in aircraft manufacturing in engineering. Therefore, lightweight has been greatly developed in aviation research and has played an increasingly important role in construction machinery. This paper presents a brief description of the current status of lightweight in machinery by reviewing some significant progress made in the last decades. Potential research topics are also discussed from the four aspects of material, structure, bionics, and manufacturing, and they forecast the development trend of lightweight in the future construction machinery. The entire body of literature about the field is not covered due to the limitation of the length of paper. The scope of this review is limited and closely related to the development of lightweight technology in engineering applications.

The static properties of leaves with parallel venation from terrestrial orchids of the genus Epipactis were modelled as coupled elastic rods using the geometrically exact Cosserat theory and the resulting boundary-value problem was solved numerically using a method from Shampine, Muir and Xu. The response of the leaf structure to the applied force was obtained from preliminary measurements. These measurements allowed the Young’s modulus of the Epipactis leaves to be determined. The appearance of wrinkles and undulation characteristics for some leaves has been attributed to the small torsional stiffness of the leaf edges.
