And Performance

Over the past few decades, digital tools have become indispensable in the field of architecture. The complex design tasks that make up architectural design methods benefit from utilizing advanced simulation software and, consequently, design solutions have become more nature-adapted and site-specific. Computer simulations and performance-oriented design enable us to address global challenges, such as climate change, in the preliminary conceptual design phase. In this paper, an innovative architectural design method is introduced. This method consists of the following: (1) an analysis of the local microclimate, specifically the wind situation; (2) the parametric shape generation of the airport terminal incorporating wind as a form-finding factor; (3) Computational Fluid Dynamics (CFD) analysis; and (4) wind-performance studies of various shapes and designs. A combination of programs, such as Rhinoceros (Rhino), and open-source plug-ins, such as Grasshopper and Swift, along with the post-processing software Paraview, are utilized for the wind-performance evaluation of a case study airport terminal in Reykjavik, Iceland. The objective of this wind-performance evaluation is to enhance the local wind situation and, by employing the proposed architectural shape, to regulate the wind pattern to find the optimal wind flow around the designed building. By utilizing the aforementioned software, or other open-source software, the proposed method can be easily integrated into regular architectural practice.

<p>The traditional design method of high-rise building structure often has a lot of redundancy, on the one hand, it consumes a lot of engineering materials and energy, and there is a large space for optimization; on the other hand, due to the failure of rational and effective use of structural materials, it may lead to increased safety risks. In addition, the traditional design method is based on experience judgment and manual iteration, so the design workload is heavy and the design efficiency needs to be improved. In this paper, based on the bi-directional evolutionary structural optimization, the optimal seismic design of a braced steel frame tall building is carried out. The results show that the algorithm can reasonably distribute the materials to each member, and achieve an efficient seismic optimization design.</p>

Integrally Stiffened Panels

Recent development in structure optimization offers the potential for significant improvements in the design of more durable structures. The present paper reveals the importance of structural optimization with crack propagation life of integrally stiffened panels. In the full paper, we explain in detail how to optimize structural fatigue life and design the structure of integrally stiffened panels which has the optimization life. The first topic is: the review of existing structural optimization design method. The second topic is: optimization methodology with crack propagation life. In our optimization methodology, the RSM (Response Surface Methodology) and GA (Genetic Algorithm) are successfully applied for structural optimization design with crack propagation life. The third topic is: damage tolerance optimization of integrally stiffened panels with crack propagation life. In this paper, structural parameters: the height and location of stringer, are the design variables. The structural weight is a fixed value. Through analyzing, the optimization structure with maximum life can not simply be chosen, and the maximum life would not increase all ways while the high of stringer increased. At last, the optimization structure, which has maximum crack propagation life, is given on the integrally stiffened panels.
