To evaluate the fire resistance performance of the iTECH beam, a test was conducted for 4.7m-span-length iTECH beams under given conditions in a laboratory. The fire resistance performance of unprotected coatings of the iTECH beam has been examined, and a longer period of fire resistance was achieved by increasing the section size and decreasing its load ratio. Coating for the fire protection of iTECH beams reduce the rate of temperature rise of the beam in case of fire, and the required thickness of spray-on fire protection coatings can be determined by means of tests. Before reviewing the fire test, I will present the basic concepts of the iTECH composite beam. Then, I will present the fire-resistance test overview and test results. The name of this composite beam is \" iTECH\", which means \" Innovat ive\" , \"Technical\", \"Economical\", \"Convenient\" and \"Hybrid System\". This composite beam was developed mainly for the purpose of reducing the story height of high-rise residential steel buildings. This figure compares the \"conventional composite beam\" and the \"iTECH composite beam\". By adopting this floor system, a story height reduction of about 200 mm can be obtained. The advantages of a reduced story height are : First, increased number of stories and more lease area, second, reduced exterior and interior wall space, and third, reduced air conditioning and heating space.

Wakamatsu","doi":"10.3210/FST.26.315","DOIUrl":"https://doi.org/10.3210/FST.26.315","url":null,"abstract":"The construction methods that exposed the steel tube surface from an aspect of architectural design may be used for columns of steel structures, and the method of double tubular steel columns is also one of them. The double tubular steel column secures the fire resistance performance by making some space outside the steel tube that bears load, and installing the finish steel tube. Generally, this space is filled up with cement mortar or insulation material. However, the part directly exposed to fire heating is the outside steel tube, and since the inside steel tube has the space. Even if the fillers are not used, the temperature of the inside steel tube will not increase rapidly. It is expected that the temperature rise of the inside steel tube is governed by the radiative heat transfer from the heated outside steel tube rather than convective heat transfer from the air of the space. Therefore, if the emissivity on the surface of steel tube is low by fitting of paint etc., the effect that controls the temperature rise of the inside steel tube is expectable. So, in this research, the fire resistance tests of the double tubular steel column which galvanized the outside steel tube are carried out. The temperature rise of each part of the member that the heat-resistant paint with low emissivity was applied on the perimeter surface of the inside steel tube, is compared with the temperature rise of each part of the steel that is not applied, and the influence that contributes to improvement in fire resistance performance is considered. In addition, Tokyo University of Science has applied for the patent about the fire-resistant construction method of the double tubular steel column with such heat-resistant paint.","PeriodicalId":12289,"journal":{"name":"Fire Science and Technology","volume":"32 1","pages":"315-319"},"PeriodicalIF":0.0,"publicationDate":"2007-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"81098588","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, it was presumed to be not clear what the margin the design limit had against the collapse of the whole frame because the relation between the collapses of a member, the partial frame, and the overall frame was not sufficiently taken into consideration. In this research, focusing on the effect of the stress redistribution on the ultimate temperatures of the overall frame that seismic design was carried out, the relation between the collapse of the overall frame and the total buckling of heated columns was considered by analysis results.","PeriodicalId":12289,"journal":{"name":"Fire Science and Technology","volume":"13 1","pages":"333-338"},"PeriodicalIF":0.0,"publicationDate":"2007-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"81128490","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Regarding the curve of the heat release rate (hereinafter, HHR curve), the increasing heat release rate can be expressed by the fire growth rate and the maximum heat release rate. However, it is uncertain how the fire growth rate and the maximum heat release rate change when the burning occurs in open space and inside a compartment. Therefore, in this report, a method for estimating the increased portion of the fire growth was developed in order to create a simplified model of the heat release rate curve, such as determining the calculation method of the fire growth and the maximum heat release rate. This method makes use of a variable defined as the radiative heat transfer from the smoke layer and the compartmental walls due to the combustion of a legless chair and a sofa inside the compartment.","PeriodicalId":12289,"journal":{"name":"Fire Science and Technology","volume":"57 1","pages":"523-527"},"PeriodicalIF":0.0,"publicationDate":"2007-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"78853889","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
