Fire stops for plastic pipe

Undue fire hazards may arise when plastic pipe penetrates fire-rated walls or floors. Fire stops for protecting these penetration openings are available commercially. This paper discusses the physical characteristics and operating modes of these devices. A selected number of fire stops were tested in accordance with CAN 4-S115-M85 in either horizontal (wall) or vertical (floor) configurations, using two small-scale furnaces. Reference: K. K. Choi, Fire Stops for Plastic Pipe,Fire Technology, Vol. 23, No. 4, November 1987, pp. 267–279.     

钢结构工程抗力时变模型的构建与验证

提出了一种全新的钢结构抗力时变模型,对多种影响因素在模型中的表述方式与初步取值范围展开了探讨。采用通用有限元程序提供的APDL语言将结构分析和其PDS模块的统计分析能力相结合,实现了基于蒙特卡罗（the Monte Carlo）有限元模拟方法的时变可靠度计算,并与非时变条件可靠性计算结果做出对比。经算例验证,结果表明：考虑抗力时变后,时间因素对结构的可靠性影响显著;同时文中提出的钢结构抗力时变函数在形式上是基本合理可行的。

A numerical imperfection sensitivity study of cold-formed thin-walled tubular steel columns at uniform elevated temperatures

A numerical study is carried out on cold-formed rectangular hollow section columns to evaluate the sensitivity of column failure strength to initial imperfections, stress–strain relationships and to assess the existing design methods. It is shown that the magnitude of initial local buckling imperfection has a significant effect on the ultimate strength of short columns where failure is predominantly local buckling. Its effect on long columns is relatively small. Similarly the magnitude of initial global imperfection has more influence on the ultimate strength of a long column, whose failure is governed by global buckling, than on short columns, where local buckling controls. The shape of the stress–strain relationship of cold-formed steel will have noticeable effect on the column failure load. Current design methods, for high temperatures in ENV1993-1-2 and for ambient temperature in ENV1993-1-3, can provide a valid basis of calculation but modification will be necessary, depending on the exact model of stress–strain relationship of cold-formed steel at elevated temperatures.     

Experimental study of structural fire behaviour of steel beam to concrete filled tubular column assemblies with different types of joints

This paper presents experimental results of structural fire behaviour of steel beam to concrete filled tubular (CFT) column assemblies using different types of joints. The joint types include fin plate, end plate, reverse channel and T-stub. The structural assembly was in the form of a “rugby goalpost”. In each test, loads were applied to the beam and then the structural assembly was exposed to the standard fire condition in a furnace while maintaining the applied loads. In total, 10 tests were carried out. In eight of the 10 tests, fire exposure continued until termination of the fire test, which was mainly caused by structural failure in the joints under tension when the beam was clearly in substantial catenary action. In the other two tests (one using fin plates and one using reverse channels), fire exposure stopped and forced cooling started when the beam was near a state of pure bending and just about to enter into catenary action. The results of the experiments indicate that even the relatively simple joints used in this study were able to allow the beams to develop substantial catenary action so that the final failure times and beam temperatures of the assemblies were much higher than those obtained by assuming the beams in pure bending. At termination of the tests, the beams reached very high deflections (about span/5), even then failure of the assemblies always occurred in the joints. Therefore, to enable the beams to reach their full potential in catenary action, the joints should be made to be much stronger. The results also indicate that reverse channel connection has the potential to be developed into a robust connection characterised by high stiffness, strength, rotational capacity and ductility. The beams in the two cooling tests developed high tension forces, however there was no structural failure in the assemblies. The principal aim of this paper is to present experimental results of joint behaviour in fire (which until now is lacking) to enable development of better understanding and rational design methods for robust construction of joints to resist extreme fire attack.
