EVALUATION OF FIRE PROTECTION METHODS OF STEEL STRUCTURES

摘要

entrOne of the most significant problems encountered in steel structures is their insufficient fire resistance. This problem is eliminated by protecting structural steel elements through active and passive protection methods. Active methods are fire extinguishing systems implemented to make fire ineffective by controlling the fire as of its beginning. Passive methods are protective applications designed for steel structures by considering the emergence possibility of fire. In addition to such precautions, fire escape points should be identified during design stage of the building by taking emergence of fire into consideration. Regulations arrange rules regarding locations of fire-escape, their distance to the escape points, etc. In this study, fire protection methods of steel structures are evaluated in compliance with requirements of Fire codes.?elik yap?larda g?rülen en büyük sorunlardan biri yang?na kar?? dayan?m?n?n az olmas?d?r. Bu nedenle yang?n olay? s?ras?nda yap?n?n tahliye süresince, güvenli bir ?ekilde ayakta kalmas?n? sa?layacak y?ntemler geli?tirilmi?tir. Bu y?ntemler aktif ve pasif koruma y?ntemleridir. Aktif y?ntemler, yang?n?n ba?lad??? andan itibaren yang?n? kontrol alt?nda tutarak etkisiz hale getirmek i?in uygulanan s?ndürme sistemleridir. Pasif y?ntemler ise, yang?n?n olu?abilece?i g?z?nüne al?narak ?elik yap? elemanlar?nda yap?lan koruma uygulamalar?d?r. Bu ?nlemlerin yan?s?ra bina tasarlan?rken yang?n olu?umu g?z ?nünde bulundurularak yang?n ka??? noktalar? belirlenmelidir. Y?netmelikler yang?n merdivenlerinin yerle?im yerleri, ka??? noktalar?na uzakl?klar? vb ile ilgili belirli kurallar? ortaya koymaktad?r. Yap?lan bu ?al??mada Yang?n Y?netmeli?inin gerektirdi?i esaslara uygun olarak ?elik yap?lar?n yang?na kar?? korunma y?ntemleri de?erlendirilmi?tir.
