This work introduces to the international scientific community the Chinese Code on fire safety design of steel building structures. The aim of the Code is to prevent the structure of a steel building subjected to fire from collapsing, ensure safe evacuation of building occupants, and reduce the cost for repairing the damages of the structure caused by fire. The main contents of the Code is presented in this paper, including the fire duration requirements of structural components, fundamental requirements on fire safety design of steel components, temperature increasing of atmosphere and components in fire, loading effect and capacity of various components in fire, and procedure for fire-resistant design of steel components. The analytical approach is employed in the Code and the effectiveness of the Code is validated through experiments.

This research studies in the field of domestic fires are an issue in many scientific fire research as a research method to validate the domestic environment and ISO-9705 housing on the basis of experiments in virtual space by making a single fire compartment space for conducting experiments and Appearance of a fire occurring within each flammable Heat Release Rate analysis was carried out mainly. Placed within the space of one flammable HRR calculated as the sum of the number of single-room fire experiments conducted and the results compared with the value in comparing the conduct of fire locations and fire load within the building area of the future, the HRR value represents the change in domestic a consideration of the safety of the building is to propose matters.

The Urban-type building is an building that it relaxed the construction standard and subsidiary facility standard. The most of the urban-type buildings are pilotis, the main case of representing these building's fire risk is the Uijeongbu fire this study investigated to piloti urban type housing risk on the basis of Uijeongbu fire, and we checked structural problem that unable to escape from the rooftop inside the piloti. also, there was confirmed limit to the evacuation of the occupants because the smoke was rapidly transferred to the top layer through inside the electric duct. and when we analyzed smoke flow use of Fire simulation, it was confirmed Available Safety Egress Time that is four minutes of CO.

Fire resistance properties and mechanical properties of high strength concrete mock-up column using organic fiber by KS F 2257 Methods of fire resistance test for elements of building construction and compression test was investigated for application of precast concrete column method of high rise building in this study. As a test result, it was appeared that ECC permanent form is available as fire resistance method of high strength concrete and new precast concrete construction method for facilitating construction of high rise building.

A fire in a steel framed building can decrease a structural stability and cause deformation. And the fire continues the building can be demolished. Therefore, every country requires fire resistance performance of structural elements. In case of column, fire protective thickness derived from a specific fire test using an horizontal furnace is allowed to apply any kinds of sections and lengths of column. However, the lengths and sections of the column in steel framed buildings are various. In this paper, to know the differences of fire performance of steel column according to variance of lengths, a maximum allowable stress, steel surface temperature history, deflection are calculated and the thickness of fire protective material for longer column(4700 mm) need to enforce about 10% more than shorter column (3500 mm).

Due to the nature of modern society, buildings are becoming larger and more complex. As a result, the design conditions of the building are changing. However, despite the complexities of buildings, the fire resistance performance is still equalized to one hour without considering fire engineering analysis in Korea, so there is a risk according to actual fire design conditions. Therefore, the purpose of this study is to calculate the required fire resistance time for actual fire through fire mechanics analysis and case study.

The prediction performance of design fire curves was evaluated using a Fire dynamics simulator (FDS) for a solid fuel fire in a building space by comparing the results with experimental data. EDC 2-step mixing controlled combustion model was used in the FDS simulations and the previously suggested 2-stage design fire (TDF), Quadratic and Exponential design fire curves were used as the FDS inputs. The simulation results showed that smoke propagation in the building space was significantly affected by the design fire curves. The predictions of simulations using design fire curves for the experimental temperatures in the building space were reasonable, but the TDF was found to be the most acceptable for predicting temperature. The predictions with each design fire curve of species concentrations showed insufficient agreement with the experiments. This suggests that the combustion model used in this study was not optimized for the simulation of a solid fuel fire, and additional studies will be needed to examine the combustion model on the FDS prediction of solid fires.

The use of high-strength concrete has increased for its excellent structural stability as buildings become higher and bigger than ever before in Korea and overseas recently. The functional requirement of building materials has also been bolstered so for the high -performance, high-quality construction materials to be used more extensively. However, the internal structure of the high-strength concrete is very dense so spalling can be caused during fire. The spalling in turn can cause critical structural damages followed by the fatal consequences, demolition of the building. Therefore, ensuring fire safety for high-rise buildings is assumed to be urgent. Alumino-silicate fire resistant board producing technology has been developed in situations that new materials with excellent fire resistance and easy installation has been sought. The alumino-silicate fire resistant board turned out to exhibit not only fire resistance and excellent physical and dynamical characteristics but also excellent onsite applicability and easy process and transportation after completing Mock-up test. Its excellence as a high-performance building materials was proven.

Fire safety engineering is a critical specialization to include in the design of a tall building yet is often excluded from the Building Information Model (BIM) and integrated design process. The design of fire safety systems is interdependent with building/structural geometry, HVAC, mechanical, and electrical systems. A BIM is a 3D visual representation that stores data on these kinds of systems. The compatibility between BIM and fire safety design seems obvious yet has received a dearth of attention in structural (fire) engineering literature. The authors herein have reviewed over 40 recent papers on utilizing BIM for fire safety engineering, focusing on contemporary literature to obtain a more up-to-date review of the state-of-the-art. The resulting trends, technologies, research gaps, and methodologies are presented in this paper. Adoption of BIM in fire safety engineering is slow and behind other disciplines which may be improved if research involved more industry partners. For BIM technology to reach its potential, industry manufacturers need to provide high LOD fire BIM objects, fire engineers and researchers need to collaborate on future advancements, and building owners/management need to be educated on how to use the benefits provided.
