The more repetitive, complex and objective the work, the more effective automation is. Code checking is an example of this. Checking building codes through a thick set of drawings is error-prone and time-consuming. In order to overcome this problem, several organizations have initiated efforts to automate building-code checking. Initiated study mainly focused on checking codes for invalidation, required size and crash, and then area of checkable codes have been expanding. But, it has not been considered for codes regarding anti-disaster/egress, which is also issued these days. This study is about how to automatically check codes for anti-disaster and egress based on Korea building codes. The codes can be categorized as five sections: egress way, material/capability, principals of evacuation, evacuation stairway and fire protection partition. To check automatically, there are problems, such as expression of codes for egress and limitation of extractable information from the BIM model. This paper shows what problems exist and assignments to be resolved. Also, current developing processes are presented, and suggestions are made about the direction for the work that remains.

The movement towards sustainable building design can result in unique fire protection challenges and concerns, especially with super tall buildings in relationship to traditional prescriptive code compliance. Different countries haves different code requirements as well as local best practices and may cause conflict with the design features when designing green buildings. These include, but not limited to green roofs, sprinkler water quality and testing, fire department access and areas of refuge with direct or indirect impact by the perspective code compliance. The solutions to these prescriptive code challenges and fire safety concerns can range from simple alternatives to more detailed engineering performance-based design analyses with good solid practice.

최근 건축물이 대형화, 복잡화되면서 예기치 못한 상황에 대한 안전성 문제가 이슈화되고 있다. 그러나 초대형 건물의 경우 규모가 커서 수작업으로 방재 및 안전성과 관련한 법규 검토에 시간이 많이 걸리고, 실수가 일어날 가능성도 높다. 이러한 문제로 한 조사에 따르면 건축 및 건설관련자-실무자의 83%가 자동법규검토 시스템이 필요하다고 응답하였다. 본 연구는 기존의 자동법규검토 시스템 및 연구현황을 살펴보고, 기존 BIM기술을 이용하여 국내 방재 및 피난 관련법규를 자동으로 검토하기 위한 시스템개발 가능성을 검토하고자 한다. 이밖에 자동법규검토 시스템의 필요성과 그 기대효과를 분석하고 기존 연구사례를 통해, 국내 적용가능 여부를 검토하고, 지역적 특수성에 대한 문제점, 한계를 논의한다. 또 그러한 문제점들에 대한 해결책과 향후 발전방안을 제시한다. 본 연구에서는 피난관련 법규로 그 범위를 제한하였지만 앞으로 전체적인 법규 자동검토시스템이 구축되기 위해 필요한 노력과 작업에 대해 알아보고 연구해 나가야할 것이다.

This research traces the history of legislative matters regarding the enactment and revision of laws and regulations related to the outdoor landscape in apartment complex. The years before 1976 can be classified as 'a period of darkness' for the landscape in apartment complex due to absence of landscape legislation. From the year of 1977 when the landscape planting and mere necessities were carried out according to the local administration's building standard to the year of 1990 can be classified as 'a period of quickening'. The year of after 1991 when the enactment of the code#32 called "the green space in site" in the "Korea Building Code" and the "Korea Housing Standard & Regulation" was made, and various construction regulations and provisions were revised in order to improve the scantiness of the apartment complex and its environment should be called 'a period of development'.

Recently, construction projects are gradually becoming high-rise and large-scale, and furthermore, the use of new buildings is emerging through the deepening of the underground. In this situation, a lot of fire damage has occurred in recent years, mainly in buildings and tunnel structures. In particular, damages caused by fires during large-scale construction projects such as freezing warehouse accidents are increasing. In this situation, in Korea, it is still trying to secure safety from human fire through the administrative system divided into the building law and the fire law, but it is being developed in a negative direction rather than a positive direction. The fire risk is getting bigger even when the road is not maintained. In this current situation, it is considered that the development of a Korean integrated life safety code centering on the consciousness base of Koreans will be necessary, and in particular, the ease of revision will also be needed by promoting the integrated safety code rather than current laws and regulations. This is a summary of the future tasks.

An efficient code has been developed to predict dispersion of indoor air pollutants. The computing capability of the code has been compared with that of a commercial code in a benchmark test. After that, the code has been employed to compute dispersion of a pollutant released from a new furniture, a kind of Sick Building Syndrome(SBS). A sofa which generates formaldehyde is implemented by using an immersed boundary method. Large Eddy Simulation (LES) is employed to obtain time-dependent velocity and concentration fields. LES has been regarded as an academic tool, but the newly-developed code reveals a possibility of application of LES to practical problems, especially dispersion of indoor pollutants.

ACK는 가상 스택 기계에 기반을 둔 EM 중간 코드로부터 레지스터 구조에 기반을 둔 SPARC 기계에 대한 목적 코드를 생성하기 위해서는 코드 확장기(code expander)를 이용하고 있다. 따라서 EM 코드로부터 SPARC 목적 코드를 생성하기 위해 스택 지향 구조로부터 레지스터 지향 구조로 변환하여야 한다. 코드 확장기를 이용한 SPARC 코드 생성 기법은 각 EM 명령어에 대해 SPARC 코드로 확장하는 루틴들로 구성되며 코드 생성기에 비해 코드의 질을 개선하기 위해 푸쉬-팝 최적화 동작을 수행한다. 하지만 코드 확장시에 별도의 자원과 관리를 요구하는 혼합 스택(hybrid stack)을 이용하고 있으며 전단부의 정보 손실로 레지스터 윈도우를 이용한 효율적인 매개변수 전달을 고려하지 않는다. 본 논문에서는 ACK의 전체적인 구조의 변경 없이 목적 기계의 스택과 매개변수 전달을 고려하나 효율적인 SPARC 코드를 생성하기 위해 EM 트리를 이용한 SPARC 코드 확장기를 설계하고 구현하였다. 이를 위해, 순차적인 EM 코드를 입력으로 받아 스택 속성을 반영한 트리로 구성하며 혼합 스택을 제거하기 위해 지역 변수 정보를 별도로 관리하였다. EM 트리의 순회 및 확장 과정에서 목적 코드를 생성할 수 있는 루틴을 통하여 목적 코드를 출력하며 추출된 정보와 노드의 성격에 출력 시기와 목적 코드를 결정한다.

The continuing trend of built environment set forth by the rise of modernization and industrialization has led every country in achieving their respective economic development. Along side this trend is an issue that needs to be addressed - the environmental impacts of the built industry. Construction and maintenance of buildings are said to consume 40% of the world's energy, 65% of electricity, and 40% of raw materials, creating drastic pollutants harmful not only to the environment but also to human. Figures have been released and analyzed proving the contributions of built environment with environmental depreciation. Said figures earned concerns not just from different private and non-profit organizations but also the governments of every country, thus, steps towards sustainable development are being implemented. As a response, the "green" was added in the built environment. Later on, the now emerging concept of "National Green Building Code" found its role in the policy of various states in protecting the people in accord with the nature. This paper appreciates the initiatives of various countries and non-profit organizations in their drive to pursue sustainable green built environment in general, and specifically proposes an establishment of an "incentives grant framework" as an additional legislative policy to be included in the draft of the National Green Building Code of the Philippines.

The current 2002 Indonesian Seismic Code consists of prescriptive criteria that are intended to result in buildings capable of providing certain levels of performance. However, the actual performance capability of buildings is not assessed as part of the code procedures. Several analysis procedures are allowed, and the state of practice is to use the RSA with six-zone seismic map developed for 475-year earthquake. This code is being revised and will adopt many of the ASCE7-10 provisions and 2475-year earthquake for MCE. The growth of tall buildings compels engineers to look for more optimal lateral system. The use of RC core wall as single system has been adopted by very few engineering firms, which is allowed in the current code but will no longer be the case if the new one is in effect. Other innovative structural system such as core wall and outrigger is not addressed in the proposed new code. Engineers must then resort to NLRHA. Currently, one 50-story building under construction using RC core wall and outrigger has been designed with RSA and employing capacity design principles, then evaluated using NLRHA per TBI Guidelines. Based on the evaluation, the performance of the 50-story building generally still meets the criteria of the TBI Guidelines. The result of the case study is presented in this paper.

This study was performed to develop an LRFD (Load Resistance Factored Design) Code for Domestic Larch. To accomplish his, we evaluated bending, compression, tension and shear strength. The results of the strength evaluation were utilized to verify the distribution and code conversion. For bending, tension and compressive strength, the Weibull distribution was well-fitted, but for shear strength we observed a normal distribution. For evaluating the bending and compressive strength, a full-sized specimen was used. A small clear specimen was used to test tension and shear strength. Compressive strength in particular was found to be affected by tight knots, although there was little difference between grades. In the code conversion, the design value of the LRFD was larger than the existing allowable stress value in the Korean Building Code. However, the allowable stress in this study was about two times higher than the value listed in the Korean Building Code. This result induced the difference between the soft and hard conversions. For greater reliability, the accumulation of additional data is necessary and further studies should be performed
