Proper Balance

After sufficient consideration for the proper balance between material and formal constraints, this chapter describes a pedagogical approach that transforms the education of future architects through a 'form-finding' method, allowing the material to accommodate itself to form and celebrate its own nature. To enhance pedagogical improvement of foundational studies in architecture and further explore this pedagogy based on form-finding in early design education, this chapter also presents the challenges to integrating materiality within the design process, as derived from the incorporation of experimental form-finding methods into early-stage design.

Tensegrity structures is a light-weight structure compared to concrete structures that are heavy and rigid in shape. The studies on form-finding for tensegrity configuration are still ongoing and have been extensively conducted. Additionally, many proposed tensegrity structures have not been built for real applications. This study aims to determine potential self-equilibrated configurations of three-stage Class I tensegrity model assemblage with triangular cells, which may be applied as deployable towers. The form-finding methodology involves phases in establishment of desired form and formulation for the self-equilibrated state. The system of equilibrium equations was solved by Moore-Penrose generalized inverse method.  A range of twist angles 10o – 50o for triangular cells was investigated in the form-finding process.  It was found that the form-finding method via changing of twist angles has successfully search self-equilibrated tensegrity models.

Corrosion Of Steel

For bridge structures using the traditional steel material, some problems are hard to solve, such as corrosion of steel bar and fatigue of steel deck. And the self-weight stress of the traditional high-strength steel as the material of cable stayed and suspension bridges will limit the main span and load-carrying. As a new type of high performance structural material, fiber reinforced plastic (FRP) has many advantages, such as small mass density, high tensile strength, excellent corrosion and fatigue resistant ability. Therefor in recent years, it has attracted much attention by the construction industry. In this paper, characteristics of FRP material are introduced and then applications of FRP material in bridge structures are discussed.

This paper takes the new type of mining truck bucket as research object and analyzes the strength and rigidity of the truck body in typical situations of dead load, swerve and slanting load. According to the analysis, the author will put forward four improvement measures in the stress concentration parts and give optimization design to those parts that have much allowance to the strength of the truck structure. The calculating result indicates that the improvement of the truck structure can significantly reduce the peak stress and improve the working life of the truck. In the premise of guaranteeing the strength of the truck structure, the weight of truck bucket induces from 30t to 27.1t achieves the goal of lightweight.
