The high-rise building is a dramatic phenomenon and a powerful expression of architecture in the modern civilization. The architecture of these high-rise buildings has been developed with mutual contributions of architectural aesthetic form and advanced technologies. Architecturally the significant evolution of tall buildings from ancient towers is a "change of function" from some religious symbols to a commercial concept that has aesthetically become acceptable with the changing of modern society and culture driven by a technological evolution. Generally, this commercial function in the evolution of high-rise building is office where high-rise working style is simply a necessity to meet quantitative market demands since this style in major cities around world has been changed from low-rise to high-rise during the last several decades in influenced of the modern industrial society. To achieve optimum spaces with architectural aesthetics in the high-rise building, the design has become collaborative, requiring the input of architects, engineers, economists, and other consultants. Hence, architects must deeply understand the basic planning theories of high-rise buildings and try to find optimum planning between architectural aesthetics and other issues. For the approach, we can firstly start with measurement and analysis of the planning use situation for major planning issues of high-rise buildings in practice. Therefore, this study is to analysis Design Elements and to find commonly used planning strategies, tectonic, of high-rise building in practice. It will give a chance to confirm commonly used planning and then becomes the starting point of the planning development of high-rise buildings based on practical planning issues.

When planning buildings, safety should be considered as a priority over any other performance. The study aims to derive and systematize elements that can be reflected in the design stage, which affects the safety of construction workers and building users. The elements for safety of workers are classified by type of work, and the elements for safety of users are classified by fields. Elements that are difficult to be reflected in design stage or those whose effects are insignificant are excluded. In addition, application scenarios have been proposed for each element so that the elements created in this study can be directly applied and utilized in practice. This will contribute to lowering the accident rate of construction projects by evaluating the harmful risks of construction projects at the design stage.

건축교육의 궁극적 목적은 아름답고 안전한 건축물을 기능적으로 잘 설계하고 시공하는 것에 있다고 볼 수 있다. 그러한 측면에서 건축교육에 있어서 설계와 시공은 비록 서로 다른 영역으로 분리되어 있지만 그것은 단계적 구분에 불과하다. 따라서 건축을 교육하는 대학에서도 이러한 두 영역을 접목하는 교과과정을 프로그램으로 개발하여야 필요가 있으며, 스틸하우스 교육은 그러한 목적에 가장 적합하다고 할 수 있다. 한국기술교육대학교 건축공학부에서는 이러한 측면에서 지난 10년 전부터 스틸하우스 교육을 시행하였고, 건축학과 건축공학 전공이 분리된 이후에도 두 전공의 공통 교과목으로 운영하였다. 일반적으로 단기간에 이루어지는 스틸하우스 교육과정이 단순작업을 위주로 편성되어 있는 것에 반하여 대학에서의 교육 프로그램은 이론과 설계 교육 프로그램을 추가하여 졸업 이후 단순작업자가 아닌 중간관리자(실천기술공학자)로서의 역할을 담당할 수 있도록 하였다. 본 연구에서는 대학교에서 스틸하우스 교육프로그램을 효과적으로 운영하기 위한 지침이 될 수 있도록 교과편성과 프로그램 구성 및 운영에 관한 내용을 제시하고자 하였다.

Art Nouveau was a short-lived European phenomenon in art and architecture. Despite the fact that Art Nouveau architecture never fully succeeded as an anti-historical movement, it is important to identify its place in modern architectural historiography. The significance of Art Nouveau-that it incorporated decorative elements into the centre of architectural practice-certainly serves to acknowledge its place within the Modern Movement. Architectural works of Victor Horta, Hector Guimard and Charles Rennie Mackintosh are carefully examined in this paper to find out (1) how they individually emerged and manifested distinctive characteristics and creativity within their own local contexts, and (2) how they can collectively fit into historical discourse of Art Nouveau. Art Nouveau was not a mere fin-de-ci cle phenomenon, but a complicated transient phase at the dawn of European Modernism.

This article presents a proposed analytical methodology to determine seismic force-resisting system R-values for steel diagrid framed systems. As current model building codes do not explicitly address the seismic design performance factors for this new and emerging structural system, the purpose of this study is to provide a sound and reliable basis for defining such seismic design parameters. An approach and methodology for the reliable determination of seismic performance factors for use in the design of steel diagrid framed structural systems is proposed. The recommended methodology is based on current state-of-the-art and state-of-the practice methods including structural nonlinear dynamic analysis techniques, testing data requirements, building code design procedures and earthquake ground motion characterization. In determining appropriate seismic performance factors (R, ${\Omega}_O$, $C_d$) for new archetypical building structural systems, the methodology defines acceptably low values of probability against collapse under maximum considered earthquake ground shaking.

This study presents conceptual information of newly optimized shapes and connectivity of the so-called outrigger truss system for modern tall buildings that resists lateral loads induced by wind and earthquake forces. In practice, the outrigger truss consists of triangular or Vierendeel types to stiffen tall buildings, and the decision of outrigger design has been qualitatively achieved by only engineers' experience and intuition, including information of structural behaviors, although outrigger shapes and the member's connectivity absolutely affect building stiffness, the input of material, construction ability and so on. Therefore the design of outrigger trusses needs to be measured and determined according to scientific proofs like reliable optimal design tools. In this study, at first the shape and connectivity of an outrigger truss system are visually evaluated by using a conceptual design tool of the classical topology optimization method, and then are quantitatively investigated with respect to a structural safety as stiffness, an economical aspect as material quantity, and construction characteristics as the number of member connection. Numerical applications are studied to verify the effectiveness of the proposed design process to generate a new shape and connectivity of the outrigger for both static and dynamic responses.

The post-tensioned (PT) flat plate slab system is commonly used in practice, and this simple and fast construction method is also considered to be a very efficient method because it can provide excellent deflection and crack control performance under a service load condition and consequently can be advantageous when applying to long-span structures. However, a detailed design guideline for evaluating the lateral behavior of the PT flat plate slab system is not available in current design codes. Thus, typical design methods used for conventional reinforced concrete (RC) flat plate slab structures have inevitably been adopted in practice for the lateral load design of PT flat plate structures. In the authors' previous studies, the unified equivalent frame method (UEFM) was proposed, which considers the combined effect of gravity and lateral loads for the lateral behavior analysis of RC flat plate slab structures. The aim of this study is to extend the concept of the UEFM to the lateral analysis of PT flat plate slab structures. In addition, the stiffness reduction factors of torsional members on interior and exterior equivalent frames were newly introduced considering the effect of post-tensioning. Test results of various PT flat plate slab-column connection specimens were collected from literature, and compared to the analysis results estimated by the extended UEFM.

구조물의 고층화가 진행됨과 동시에 효율적인 기초 설계를 위해 대구경 PHC 말뚝의 사용이 증가하고 있으며, 특히 600mm PHC 말뚝의 사용량이 급증하고 있다. 본 연구에서는 현재 사용되고 있는 설계법의 적정성을 평가하기 위하여, 직경 600mm PHC 매입말뚝에 대하여 수행된 46본의 동재하시험 결과를 분석하였다. 선단지지력은 초기항타시험의 결과를 이용하였으며 주면마찰력은 재항타시험 결과를 이용하여 각각의 허용지지력을 산정하였다. 동재하시험으로부터 산정된 허용지지력을 현재 사용되는 설계법으로 평가된 허용지지력과 비교하였다. 분석결과, 동재하시험으로 산정된 허용선단지지력은 대부분의 말뚝에서 설계기준보다 컸지만, 허용주면마찰력은 많은 말뚝에서 설계기준보다 작게 산정되었다. 이와 같은 큰 선단지지력과 작은 주면마찰력은 천공장비의 성능 향상 및 굴착 깊이의 증가 때문이며 이로 인해 전체지지력에서 선단지지력이 차지하는 비율이 높아졌기 때문이다.

Code-compliant seismic design should be essentially applied to realize the so-called emulative performance of precast concrete (PC) lateral force-resisting systems, and this study developed simple procedures to design precast industrial buildings with intermediate precast bearing wall systems considering both the effect of seismic and blast loads. Seismic design provisions specified in ACI 318 and ASCE 7 can be directly adopted, for which the so-called 1.5S_y condition is addressed in PC wall-to-wall and wall-to-base connections. Various coupling options were considered and addressed in the seismic design of wall-to-wall connections for the longitudinal and transverse design directions to secure optimized performance and better economic feasibility. On the other hand, two possible methods were adopted in blast analysis: 1) Equivalent static analysis (ESA) based on the simplified graphic method and 2) Incremental dynamic time-history analysis (IDTHA). The ESA is physically austere to use in practice for a typical industrial PC-bearing wall system. Still, it showed an overestimating trend in terms of the lateral deformation. The coupling action between precast wall segments appears to be inevitably required due to substantially large blast loads compared to seismic loads with increasing blast risk levels. Even with the coupled-precast shear walls, the design outcome obtained from the ESA method might not be entirely satisfactory to the drift criteria presented by the ASCE Blast Design Manual. This drawback can be overcome by addressing the IDTHA method, where all the design criteria were fully satisfied with precast shear walls' non-coupling and group-coupling strength, where each individual or grouped shear fence was designed to possess 1.5S_y for the seismic design.

Purpose: To prove the credibility of EBD, it is necessary to define concepts regarding the nature of credible knowledge and the hierarchy of evidence. In addition, the relationship between EBD and EBP needs to be addressed through a practical viewpoint. Methods: The systematic review is applied to define the nature of knowledge and the characteristics of research papers in architectural EBD while analyzing the field of study, knowledge focus and types of keywords of the first author. Results: As a whole, the types of research focus evaluated using the most frequent keywords include function(40.86%), specialized knowledge(30.52%), professional practice(21.37%), and health(5.78%). Empirical research(83.72%) is more likely to be found than theoretical research(13.95%). The EBD research papers ranked as top-tier are only 7(2.03%) among a total of 344, while the research papers ranked in the third to fourth tiers are 276(80.23%). Implications: There is a deficiency of reliable 1-2 tier research papers. From a practical viewpoint, it would be realistic to recommend that healthcare architects appropriately evaluate the quality of EBD research and apply it in practice, rather than to conduct EBD research themselves. This systematic review illustrates the nature of EBD research.
