국악전용 공연장으로 지어진 국립국악 소극장의 음향 특성을 실내 음선도, 암소음, 잔향시간 및 음압분포에 의해 분석.평가하였다. 연구결과 무대 앞부분과 객석모서리에서 음선경로차가 17m 이상으로 나타나 회주공조현상의 발생이 예측되며 남부순환도로와 인접하여 소극장내에 높은 암소음이 측정되었다. 잔향시간의 측정결과 과다한 실내 흡음력으로 인해 공석시에 계획값 보다 0.8초 정도가 짧으며 이는 관객입장시 더욱 악화될 것이 예측되어 1석당 실용적을 증가와 실내 흡음력을 가능한 줄일 필요가 있다. 음압레벨은 음악당 전 객석에서 고른 음압분포가 보이고 있으나 무대 음원에서 객석전열 사이에 초기 음압감쇠가 크게 나타나 무대주변의 음압 보강이 요구된다.

As performance-based design (PBD) has a direct impact on evacuation safety assessments, designing fire scenarios based on real fire tests is essential. To improve the reliability of the PBD for fire safety in multiplexes, information on fire behavior, such as heat release rate (HRR) and fire spread rate, are provided in this study by conducting a standard fabric flammability test. To this end, several chairs were arranged in a pattern that resembled a theater-style seating. The peak HRR and heating value per unit mass for each chair ranged from 415 kW to 988 kW and 15.2 MJ/kg to 23.8 MJ/kg, respectively. The heating values per unit mass of the new and old chairs were 23.6 MJ/kg and 16.7 MJ/kg, respectively. As the quantity of plastic and cushioning materials in the new chairs was more than that of the old ones, the new chairs were more vulnerable to fire hazards. Furthermore, when the chairs were arranged in a line, the fire spread rate was observed to be 0.39-0.42 m/min, regardless of the ignition location. Finally, a fire growth curve showing the peak HRR and fire spread rate was also demonstrated.

In this Paper, the effect of stage ceiling height on the acoustic characteristics of rectangular concert halls are investigated. To find out the acoustic properties of audience area, A simple Boston Symphony Hall(BSH) model which is typically rectangular shaped was applied for computer simulation. A newly built rectangular concert hall with 400 seats was also chosen for a scale model $(1.2m{\times}0.68m{\times}0.31m)$ study and its computer simulation varing the stage ceiling height and the volume. The results show that RT increased as the stage ceiling was lowered and the difference rate of RT by its variance is from -0.09 to -0.06[sec/m].

Due to the recent Law on facilities Improvement in public performance facilities, equal access to the need of cultural satisfaction and the standards of facilities for people with disabilities are to be assessed. The aim of this study was to determine how to improve the facilities for disabled individuals and provide complementary guidelines for amenities designed for people with disabilities based on a comparative analysis of the disability codes in Korea, Japan, USA, Australia and Canada as well as a field observation. The results suggest the need for improved guidelines in terms of accessibility and accessible seating, which are summarized as follows: (1) The facility standards need to be complemented and clarified in terms of a detailed description, (2) regarding facilities for accessible seating, fall prevention handrails should be lowered to a height within the range of vision of the individual (3) The purpose and user's manual for theater and cultural facilities as well as detailed dimensional requirements need to be restated, and (4) an improvement in accessible seating in theaters and cultural facilities is needed. The purpose of the this study is to show an arrangement of a fundamental judgement and a ground data which can be complemented in planning a public performance facilities for the people with disabilities.

In this work, the effects of fire curtain and forced smoke ventilation on smoke spread to auditorium in the stage fire of theater were investigated using the Fire Dynamics Simulator (FDS). For the stage of 31 m (Width)${\times}$34 m (Depth)${\times}$32 m (Height) in dimension, the fast growth fire condition with 10 MW of heat release rate was applied. The forced smoke ventilation was set based on the National Fire Safety Code (NFSC) and previous research. The gap distances between the fire curtain and proscenium wall was established to be 0 m and 0.5 m. When the fire curtain was attached completely to the proscenium wall without any gap, no smoke spread from the stage to the auditorium occurred, independent of forced smoke ventilation. When the gap distance between the fire curtain and proscenium wall was 0.5 m, the smoke layer in the stage descended to the lower height from the bottom than the case without the fire curtain, which was because the smoke spread to auditorium was impeded by the fire curtain. Under the same fire curtain condition, the case with the forced smoke ventilation led to decreasing the mass flow rate of outflow through the gap between the fire curtain and proscenium wall, as compared to the case without the forced smoke ventilation. Based on this study, it was confirmed that the fire curtain and forced smoke ventilation were the effective tools to hold down the smoke spread to the auditorium in the stage fire of theater.

The purpose of this study is to grasp the characteristic of indoor thermal environment from large enclosures in connection with heating condition and outdoor environment. This study has measured indoor thermal environment in accordance with heat loads from occupant for large enclosures in winter. We examined indoor thermal environment of the large enclosures in this study which include temperature distribution vertical, horizontal, seat and surface and thermal comfort environment.

A study on techniques to evaluate auditorium assignment visible efficiency using three-dimensional simulation. The most important thing to be considered is to ensure the visibility to the podium upon assigning auditorium of venues, classrooms or seminar rooms. However, since there are so many variables to be considered such as the form of the stage, the area and height of the stage, size of screen, and the distance and angle of the auditorium from the podium, the methods to assign auditorium are staying at the level of basic for a long time. Thus, in this study, we proposed simulation methodology to quantitatively evaluate the three-dimensional visible efficiency based on Visual Graph Analysis (VGA) theory. After analytical methodology manufactures application, it sets examples of visibility depending on location of screen, visibility depending on degree of height difference and visibility about three-dimensional Mass Zoning like a stage and verifies the efficacy. In addition, based on results, visibility expectation curve is drawn and the method to calculate the stepped height depending on necessary visibility is proposed.
