1 Experimental behaviour of steel columns with partial damage of fire retardant coating in fire

This paper is presenting experimental results on insulated columns subjected to fire with partial loss of protection. The description of the experimental set up is clear and detailed. The major outcomes are also described.

Not a very new idea, though useful in practice. Form the abstract it does not seem to be a very systematic investigation rather a single shot. The conclusion could also be derived by the calculation models in the Eurocodes

True it is a good topic for the conference but the number of column tested are very limited and the heat transfer analysis is missing. My point of view it will an excellent poster presentation

2 An analytical solution for Stresses in an oil tank under elevated temperature

This paper presents an analytical solution in an oil tank under elevated temperature. Unfortunately no scientific information is provided in the abstract. The abstract is 12 lines long with only 4 lines sort off describing some outcomes. There is no description of the model and the authors do not explain how they have developed this model.

The subject is very interesting. It is based on numerical simulation. From the

Abstract is very difficult to estimate the real contribution to the knowledge and

the applicability of the results for the fire safety community.

This paper investigates the behaviour of a cylindrical steel tank when an adjacent tank is on fire. This paper presents an analytical solution for the stresses in a partially filled tank under the elevated temperature regime caused by fire in an adjacent tank. This reviewer has not seen this kind of work before and it should be very interesting.

3 Shear Panel at Elevated Temperature

It can be felt that this paper might provide valuable information to the fire safety engineering community but the English should be improved. Because of the poor English it is not clear what the final version will contain. Also the authors do not explain why they decided to follow a heating curve recorded during the Cardington tests.

This appears to be an interesting contribution containing both experimental and modelling results. However, it is a little difficult to be certain as the language used is poor. A full paper would require a significantly better standard of English.

The abstract suggests an interesting topic of study. However, as written, the abstract gives very little specific information about the study. For example, I would have expected the abstract to give the main conclusions of the study, but there is none. Also the written English is very poor.

4 Connections during fire tests on building

This paper studies the global structural and thermal behaviour on a three-storey steel frame building at Mittal Steel Ostrava before demolition. The objective was to verify the prediction method of the joint temperature. Comparisons are made between the test results and the temperatures predicted for connections by the structural Eurocodes.

The work presented is of interest but the abstract as written is poor. The third sentence stops mid-sentence and the English throughout the abstract is poor. The abstract should have given an indication of what was found not just that a comparison was made. For these reasons I have given this a score of 4.

The abstract does not provide enough information for a positive judgement. Important information such as fire load and details of the construction is missing. Therefore the abstract should be extended including these details.

5 Column Behaviour during Localised Fire Test

A paper based on this abstract would contain interesting experimental results and also numerical modelling. It would add to the very limited availability of data from “real” fires

The abstract is too simple to make the theme of the proposed paper clear, though its topic is interesting.

It is a good oral paper for discussion as long there is a compartment fire tests and numerical calculation used for comparison.

6 Thermal and Structural Response of a Two-story, Two-bay Composite Steel Frame under Fire Loading

This abstract promises very interesting results based on full-scale tests of a structure subject localized fires. Information on the behaviour of structures in such fires is very limited and this sounds like a valuable contribution. More information of the T-t curves used would have enabled an even more positive review.

The subject on fire test is filling the gap between the today level of prediction

and the experimental evidence. In the abstract is mentioned he furnace test and

the size of the structure is smaller than in the real steel structures.

This paper presents valuable and new results from large-scale fire tests with conclusions drawn on the influence of the location and size of the fire. This paper will contribute to the state-of-the-art knowledge leading me to award it a mark of 9

7 Slender Steel Columns Exposed to Localised Fire

The paper offers an applicable contribution to the commonly described

problem. The description of the simulation of the heat transfer to the column

and its verification is in the abstract not described.

This abstract gives a lot of information that is rather basic to the structural engineering profession, e.g. buckling behaviour of slender columns. The only worthwhile contribution is the effect of non-uniform temperature distribution along the column length. The authors should focus their paper on this aspect, e.g. generation of temperature profile, column behaviour and design. A practical case study is welcome, but the paper should focus on the scientific contribution.

The subject of steel columns subjected to localized fires is very interesting and actual. The abstract does not provide enough information about the real new contribution for the knowledge.

8 A new method to analyze the membrane action of composite floor slabs in fire condition

This abstract describes a research on the membrane action of composite floor slabs. The abstract provides enough information regarding the new developments and comparisons with experimental results and simulations

This abstract describes another method of calculating the strength of floor slabs when subject to fire load. It mentions three other authors’ work in this area but does not identify why the suggested method is superior or earlier work lacking. On the face of it this work does progress knowledge much.

Although this is not a new area of research, a new approach to the design of composite slabs in fire is being proposed. This is a valuable area of research and it is important for different approaches to be developed and presented to test previously published methods and possibly improve on them. I have awarded this paper a mark of 8.

9 On the numerical prediction of the thermal response of steel door frames subjected to ISO 834 fire

It is not possible recognised, if it is the problem of doors of structural

behaviour. The modelling is not stressed as far as I understood.

The topic of this paper does not represent mainstream structures in fire research. Nevertheless, it is an important part of fire resistance design. If the authors do not merely repeat the information they have already presented in the paper that has been accepted for publication in Fire Safety Journal, I would recommend accepting the paper.

The paper is related to steel door frames which are considered as a non-structural element but still good to be accept as a poster presentation.

10 Development of a Transient Heat Transfer Model on External Steel Elements Based on Numerical Modelling and Experimental Studies

Based on an extensive research project a useful tool seems to be developed tackling key issues missing in current standards allowing for an improved fire design of external steel which has substantial market potential

It is not very clearly described in the abstract that what is the main achievements of the study presented in the paper.

This is a good paper dealing with an aspect of steel structural fire design where a revision is long overdue. I have seen some of the work being presented in other places. However, there are new materials and it’s also worth repeating some of the information already presented. There are a few grammatical errors.

11 Fire-Resistant Steel at Elevated Temperatures

The paper is of very high interest of promising results. The fire resistant steels

are not new but paper promising the data of material as well as the results of

test by ISO application.

Research into and the use of fire-resistant steel is not a new subject. What is new here is the development of reduction factors for a specific alloy steel. The development of the computer program has been carried out previously so one would expect the predictions against the test results to be good once the material properties are obtained. Nevertheless the results are of interest and therefore I have awarded the paper a mark of 6. I note that this was a 2-page abstract where I believe a maximum of 1-page was specified. However, this has not influenced my mark.

The paper deals with research work on the behavior of resistant steel columns at elevated temperature. Costly intumescent coating could be avoid if fire resistant steel is used. The paper should mention the costs of these two solutions. Comparisons between numerical and experimental results are made. The authors should correct the definition of the section factor A/V (surface area of the member “A” divided by volume “V”, both per unit length)

12 Full scale test of a steel and concrete composite floor exposed to ISO fire

Useful fundamental data on key issue in composite construction, worth disseminated to the community though no final results are available. The approach of fire protecting only a part of the steel structure is still under debate amongst researchers and authorities.

This paper presents the results from a recent full-scale fire test looking at the performance of composite slabs and unprotected beams. The results are used to validate or improve existing design methods. Both the fire test and comparison with the design methods will be of great interest and have not been published previously. This represents a state-of-the-art paper leading me to award it 10.

This is a good paper showing the results of full scale test of a steel and concrete composite floor exposed to ISO fire. The test was shown that the global structural stability of the floor is not affected even with a long duration fire.

13 Experimental Investigation of the Behaviour of Flush Endplate Connections in Fire

The work promised the interesting experimental data very important for

evaluation of the component method. The 18 test will bring a good contribution

to the today knowledge.

Research on the fire behavior of steel connection is always welcome because it was paid little attention in the past. In fact evidence from recent building collapses shows that connections may be the weakest link of a structure in fire conditions. The results of 18 tests on flush endplate connections presented in the paper allow the component model to be validated for elevated temperature.

Investigations on the connection behavior are a current are of research. Though the experimental work considers an isolated connection and not the whole load-bearing structure, the research may include interesting results on connections subjected to different load combinations. In this context, the effects of tying are addressed in this paper, which is an innovative approach.

14 Temperature Developments in Fire in Partially Protected Steel-Concrete Composite Joints using Intumescent Coating

Important and well structured assessment of joint behaviour in fire, which is a key uncertainty in practice. The paper covers tests, assessment and design recommendation, making it worth being presented.

This paper deals with fire tests on composite steel joint assemblies with different connection components and fire protection schemes. Several interesting conclusions are given in the paper. The author should correct EN 1993—1-2: 2005 (E)

The effect of intumescent coating depends significantly on the thickness of the applied painting. As the relationship between thickness and fire protection is nonlinear, it seems to be unrealistic predicting general rules for intumescent coating. It is expected that the results of this research are only valid for a particular product and therefore not of general interest.

15 A New Design Method for Industrial Portal Frames in Fire

The paper promised the new method and interesting findings. The problem

itself was already presented. The discussion of the influence of the base plate

stiffness will bring a clear view to the subject.

Important topic, but not completely new. The design method based on numerical work only could be a improvement of an existing method that is mainly applied in the UK and is already ahead of practice elsewhere

Interesting paper on the behavior of full-scale tests of frames with slim floor slab construction under furnace loading. It is expected that the paper will present interesting conclusions from the tests.

16 An Experimental Study on the Behavior of Full-Scale Frames with Slim Floor Slab Construction under Furnace Loading

This paper presents experimental results on slim floor. The experimental procedure is well described and the outcomes of the two tests well explained.
