“…In the Intermeshed steel connection (ISC) project, the fundamental concept is to replace the existing steel connections with conventional standardized profiles (e.g. I-Beams) with interlocking connections [13]. Projects such as the Mitoseum [14] and Adidas Herzogenaurach membrane facade showcased the combination of digital detailing and laser cutting technology for designing adaptive joint system in gridshell structures.…”

The research project presents the development of a fully digital design to manufacture process chain for high‐performance curved steel elements produced by laser cutting thin steel sheets and assembled through elastic deformation. Although there have been developments in industrial robotic setups to automate steel beam bending, these processes rely on an iterative approach and are time‐consuming and costly when there is a need for high accuracy.The paper shows how the production of tailor‐made geometric parts with interlocking connections enables the design of free‐form structure as well as the complete integration of secondary functions such as façade and mounting positions. The research is based on an integrated co‐development of the construction system, structural FEA analysis, as well as manufacturing and assembly methods. A computational tool was developed to combine geometric studies and structural analysis and to automate fabrication data. This project is situated in an industrial context to test the potential for upscaling the system and detailing techniques for the assembly of curved geometries. The potential of the system is demonstrated through the design and fabrication of a 1:1 scale canopy.

To solve the problem of vibration caused by unbalanced dynamic force and surface crack on a marine air conditioner frame, three types of optimally designed structures were developed, and the core components were simulated. Using the finite element software ANSYS Workbench, an analysis of the optimized structure strength was conducted, and the natural frequency and corresponding mode shapes of the marine air conditioner frame were obtained. By comparing modal analysis results with the entire structure under actual operating conditions, it was identified that the maximum/minimum natural frequency of the frame is significantly less than the excitation frequency of the marine air conditioner, indicating that the frame structure will not resonate under the excitation frequency. Meanwhile, strength analysis results demonstrated that the stress on the surface of the upper middle beam under the impact load is the largest, in which the maximum total deformation was approximately 20 mm; while the maximum total deformation was approximately 1.5 mm using the optimized structure design.

Steel fiber reinforced concrete (SFRC) structures have been widely adopted and attracted great research attention due to their excellent performance in resisting tension and flexure bending. However, the existing analytical and numerical analyses of SFRC structures rely mainly on the experimental data of material tests, thereby being suitable for a case‐by‐case basis. This is due to the lack of a general and reliable constitutive material model for SFRC, which analytically considers the fiber‐dependent parameters such as fiber geometry, fiber stiffness, and interface properties of fibers and concrete matrix. This study presents an approach to modify the concrete plastic damage model to represent the SFRC material constitutive relations for simulating the structural behavior of SFRC. In this approach, the general procedure to integrate the bridging effect of fibers through the pull‐out mechanism into the constitutive relation of SFRC was proposed. The comparison between the numerical and experimental results was conducted to verify the reliability of the proposed model. The results demonstrated the proposed model could well represent the material performance of SFRC and the numerical simulations could capture reasonably the effect of the volume fraction, geometry, and properties of fibers on the structural response of SFRC.
