This research suggests a novel visualization approach utilizing Generative AI to render photorealistic architectural alternatives images in the early design phase. Photorealistic rendering intuitively describes alternatives and facilitates clear communication between stakeholders. Nevertheless, the conventional rendering process, utilizing 3D modelling and rendering engines, demands sophisticate model and processing time. In this context, the paper suggests a rendering approach employing the text-to-image method aimed at generating a broader range of intuitive and relevant reference images. Additionally, it employs an Text-to-Image method focused on producing a diverse array of alternatives reflecting architects' styles when visualizing the exteriors of residential buildings from the mass model images. To achieve this, fine-tuning for architects' styles was conducted using the Low-Rank Adaptation (LoRA) method. This approach, supported by fine-tuned models, allows not only single style-applied alternatives, but also the fusion of two or more styles to generate new alternatives. Using the proposed approach, we generated more than 15,000 meaningful images, with each image taking only about 5 seconds to produce. This demonstrates that the Generative AI-based visualization approach significantly reduces the labour and time required in conventional visualization processes, holding significant potential for transforming abstract ideas into tangible images, even in the early stages of design.

Recently, greenery system is frequently applied on buildings and artificial grounds to improve urban ecological functionality. Specifically, architectural greenery is also known as an architectural language that can meet the sustainable design concept of architects. Although the architectural greenery system can be optimized through an interdisciplinary approach between architecture, horticulture and landscape- architecture, there is a problem of communication on the ideal gap between them. Therefore, this study is expected to establish the comtemporary architecture as hi-tech and the organic architecture in internationalism. Moreover, it can analyze the case study on architectural greenery system designed by a Pritzker Prize winner who represents the comtemporary architectural trend. In this analysis, we calculate and compare the U-value of the free-form surface system based on the international standards: ISO and CIBSE etc. Moreover, we calculate a change of artificial soil transmittance respect on compounding ratio of the bottom ash and pearlite. In the case of California Academy of Science by Renzo Piano, total transmittance of the greenery system results in 48% of domestic thermal insulation standard in dry condition. This result will be used as a basic study to promote developing the advanced system based on the concept of consilience.

The aim of this study on the Munich Olympic Park is to understand the characteristics and design techniques of the environmental design of G$\ddot{u}$nther Behnisch's architecture. This particular work is chosen because it represents a turning point in his architectural life in terms of his approach to environmental design. The goal of this paper is to research Behnisch's design techniques in order to realiz a way to apply nature-friendly design in contemporary-architecture. In Behnisch's architectural works, the organic design philosophies of Hugo H$\ddot{a}$ring and Hans Scharoun are clealy echoed. The site and natural surroundings are always important in his architecture. In terms of his environmentally-friendly approach, Behnisch's architecture can be defined as one which espresses a harmony between architecture and the naturale-surroundings. In terms of the structural aspect, Behnisch's architectural forms are not imposing, but rather waiting to be discovered naturally. In terms of spatial characteristics, Behnisch's spaces are based on organic characteristics and have a strong relationship between the outside and inside. In particular, the artificial architectural landscape in the Munich Olympic Park through cable-construction connects perfectly with nature.

Beam-column joints play a significant role in static and dynamic performances of reinforced concrete frame structures. This study contributes a numerical approach of topologically optimal design of carbon fiber reinforced plastics (CFRP) to retrofit existing beam-column connections with crack patterns. In recent, CFRP is used commonly in the rehabilitation and strengthening of concrete members due to the remarkable properties, such as lightweight, anti-corrosion and simplicity to execute construction. With the target to provide an optimal CFRP configuration to effectively retrofit the beam-column connection under semi-failure situation such as given cracks, extended finite element method (X-FEM) is used by combining with multi-material topology optimization (MTO) as a mechanical description approach for strong discontinuity state to mechanically model cracked structures. The well founded mathematical formulation of topology optimization problem for cracked structures by using multiple materials is described in detail in this study. In addition, moved and regularized Heaviside functions (MRHF), that have the role of a filter in multiple materials case, is also considered. The numerical example results illustrated in two cases of beam-column joints with stationary cracks verify the validity, benefit and supremacy of the proposed method.

This paper proposes an efficient approach for the structural topology optimization of bi-directional functionally graded structures by incorporating popular radial basis functions (RBFs) into an implicit level set (ILS) method. Compared to traditional element density-based methods, a level set (LS) description of material boundaries produces a smoother boundary description of the design. The paper develops RBF implicit modeling with multiquadric (MQ) splines, thin-plate spline (TPS), exponential spline (ES), and Gaussians (GS) to define the ILS function with high accuracy and smoothness. The optimization problem is formulated by considering RBF-based nodal densities as design variables and minimizing the compliance objective function. A LS-RBF optimization method is proposed to transform a Hamilton-Jacobi partial differential equation (PDE) into a system of coupled non-linear ordinary differential equations (ODEs) over the entire design domain using a collocation formulation of the method of lines design variables. The paper presents detailed mathematical expressions for BiDFG beams topology optimization with two different material models: continuum functionally graded (CFG) and mechanical functionally graded (MFG). Several numerical examples are presented to verify the method's efficiency, reliability, and success in accuracy, convergence speed, and insensitivity to initial designs in the topology optimization of two-dimensional (2D) structures. Overall, the paper presents a novel and efficient approach to topology optimization that can handle bi-directional functionally graded structures with complex geometries.

Built-up environments by humans are cultural byproducts which combine social ideology and architectural paradigm. The process of modernization in the Western countries has the characteristic of decisive paradgm based on materialism. Therefore, environmental design in modern world failed to focus on the essential features of humanity which are the subject of space and replaced it for objective and unilateral architectural environments, instead. Environment without supporting the human psychological and complicated behaviorism is as same as the hardware without the vitality. under these regards, this study will cover the design approach of pattern language as a design method of environment design. The purpose of design approach by pattern language lies in creating the space of flexibility, adaptability and strong vitality. It is summed up as humanization in space and it helps the user to verbalize individualized space language for their own. The range and method of in the study attribute to the pattern language of Christopher Alexander and a researcher' method on them. In premise that human behavior ought to the multilateral and indefinite under rapid change of circumstances in modern world, th study tried to find the design method stimulating creative behavior of human being.
