“…There can be various choices of third-party simulation software, which makes it possible to expand or customize the proposed workflow, and thus adapt to various needs in multi-disciplinary design environments. For instance, structural simulation software SAP2000 is another possible choice; it can be combined with Grasshopper by using Grasshopper's plug-in Geometry Gym; or it can also be combined with modeFRONTIER by using an Excel file (Rizzian et al, 2017).…”

There are an increasing number of optimal-design paradigms used in architectural design nowadays. In these paradigms, a design task is formulated, or partially formulated, as an optimization problem. Multi-Disciplinary Optimization and Multi-Objective Optimization, as two important optimal-design paradigms, have shown their great potential in improving the performances of complex buildings in recent decades. Nevertheless, current paradigms for ill‑defined conceptual architectural design still lack ways to ensure the achievement of a reliable optimization problem, which hinders reliable design solutions despite the use of advanced optimization algorithms. To address this problem, it is necessary to shift the focus from Optimization Problem Solving to Optimization Problem Formulation. This research particularly focuses on knowledge‑supported, dynamic and interactive Optimization Problem Re-Formulation in order to construct a new Multi‑Objective and Multi-Disciplinary Optimization (MOMDO) method suitable for use in ill‑defined conceptual architectural design. The proposed method consists of two subtype methods: Non‑dynamic, Interactive Re-formulation method (Subtype-I) and Dynamic, Interactive Re‑formulation method (Subtype-II), which can be used to explore design space in a convergent and divergent manner respectively. To support the re-formulation, various kinds of information and knowledge need to be extracted by utilizing different computational techniques, such as advanced sampling algorithms, Self-Organizing Map, Hierarchical Clustering, Smoothing Spline Analysis of Variance, Two-Level Variable Structure and modular programming. Moreover, a software workflow that can provide these computational techniques is developed; it integrates McNeel’s Grasshopper, ESTECO's modeFRONTIER and simulation software tools Daysim, EnergyPlus and Karamba3D. With the support of this software workflow, the proposed method is demonstrated via two case studies concerning the conceptual design of indoor sports halls.

In Korea, there is still no plan to secure earthquake-resistant performance in private buildings despite being exposed to the risk of large and small earthquakes. Therefore, this study considered the current status of domestic and foreign support systems as well as prior research on improving the seismic resistance rate of private buildings, and surveys of experts and residents were conducted based on them. According to the survey, direct support such as financial support for seismic reinforcement, technical/administrative support, rental housing support, and deregulation should be considered to improve the seismic resistance rate of private buildings. In addition, it is necessary to prepare a cost-effective plan and review the financial security plan. As social consensus is important for these support systems, continuous policy research is needed.

“…Peng et al [12] optimized an adaptive sliding base isolation system to prevent possible failure of isolator devices during an extreme ground motion and thus to improve the seismic performance of structures. Rizzian et al [13] presented a study on sizing optimization of seismic isolated reinforced concrete structures where optimum design main parameters were superstructure material cost, top floor displacement, and acceleration and it was revealed that when the cost of seismic isolator devices was considered, base isolation did not provide a cost advantage to the structure in total while it had positive effects in top floor response and acceleration. In a study that Jiang et al [14] conducted, isolator devices used in seismic-isolated simply supported bridge model in the near-fault region was optimized by considering the pulse effect.…”

In the study, the weight efficiency of the Triple Friction Pendulum Bearing (TFP) Isolators is investigated on optimal weight of planar steel frames. For this investigation, an optimization program based on Artificial Bee Colony (ABC) algorithm have been developed for this study. In the design of steel frames, the structure should satisfy strength, inter-story drift, top-story drift and geometric requirements that are implemented from LRFD-AISC. For the research, 8 different planar frames were optimized as seismic-isolated and fixed-based, which were diversified according to story height and bracing. According to the results, the frames with TFP isolators, especially non-braced ones are a lot more advantageous regarding the optimal weight.
