A study on Heat transfer analysis and Experiment of Reinforced concrete columns using 500℃ Isotherm method In-Hwan, Yeo, a,Kyu-Jae, Hwang,bJae-Hong, Anc and Jong-Ho, Lee,d Korea Institute of Construction Technology, Republic of Korea ayeo@kict.re.kr, bhkjthink@kict.re.kr, crehong@kict.re.kr, dljh84@kict.re.kr Keywords:unstressed tests, axial load ratio, assessment of fire resistance performance, RC columns Abstract.This study aims to assess heat transfer analysis of RC columns and unstressed test by applying 500℃ isotherm method, which is the strength deterioration estimation method of Eurocode, inorder to use it as basic data for fire engineering design.
Also, it aims to evaluate strength alleviation of RC column members, which are exposed fire, in order to use it as basic data to establish fire engineering design system, by adopting the simple method described in Eurocode for the axial load ratio affected on column members.
Annex B of EN 1992-1-2, in which fire resistance design method is described, suggests a simple method, which can be easily applied, and use of data by experiments are available for.[1] Figure 1.
The analysis results of the adopted model of RC columns showed an error range of at least 0.2% but no higher than 20%. 2) As the distance from concrete surface grew farther 10mm to 45mm while cross-sectional size increased based on 3 hours of fire resistance time, temperature reduction effect occurred up to 53.2% and 56.2% respectively. 3) Axial load ratio was calculated through remaining strength ratio estimated by experiment and analysis results.

This methodology permits the optimization of the parameters values z1, y1 by taking into consideration the production plan against minimization of the gauges number, especially the shaft gauge, what gives reduction to the product cost by cutting down the gauges fabrication costs [6].

Figure 3 shows an example of this dependency, where four clusters of data points can be clearly distinguished.
To assign data points to clusters, k-means was used.
The algorithm determined 4 clusters of data points.
Additionally, a cluster analysis were carried out on the recorded data.

ERA is a modal analysis technique which generates a system realization using the frequency response given input and output data.
As a comparison, finite element model was built to obtain the environmental stimulus response data.
The modal parameters are identified precisely only to obtain the response data.

Little however has been reported on the data from the compression set test itself.
There is good agreement between the two data sources.
This is illustrated by the data in Fig.1 for all temperatures investigated.
This observation cannot be applied to the 25% initial fixed compressive strain data.
As shown in Fig.1 this data is more widely scattered than that obtained from the 50% initial fixed compressive strain tests.

So we consider both types of features. 2.2 Dissimilarity Representation and Data Preprocessing An appropriate representation of samples is based on data.
And 200 examples are used as training data.
All the detection accuracy is low when fewer features is used on both original data and transformed data.
It’s fairly to say that if the original data cannot be described, the structure of these data isn’t exists either.
So there is no ground that the transformed data may absorb the structure information of the data.

Where M is the number of BP neural network training data, N is the smallest scale, namely, to predict the scale coefficient of the first M+1 data by the scale coefficient of the last M data; BP neural network 1 to N can use the same structure, parallel processing the N sets of data at the same time, so generating a new set of scale coefficient of each layer, as well obtaining the scale coefficient prediction output value by means of the trained network.
Step 7:Getting the multiplier by the above step 2 to step 3, then using it for the actual data to initialize the AR model, estimating parameters of AR model, and then according to (11), getting the prediction multiplier; (11) Step 8: Calculating on the basis of prediction multiplier, and to conduct wavelet inverse transformation combining with the scale coefficient, generating prediction data, as shown in fig. 1.
Predicting the first M data by the the scale coefficient prediction value of last M data and multiplier AM + 1, and so on, the first M+2 data can be predicted, etc.
Fig. 1 Predicted data generation method Fig. 2 BP neural network structure Three layers BP neural network can approximate any nonlinear function [4], as shown in fig. 2, the circles represent neurons nodes, number of nodes in each layer references experience value and the experiment value.
We conduct on experiment by "the Silence of the lambs" (from the university of Berlin mpeg-4 video tracking database [5]), As known in fig. 3, it may be observed that when the size of a video frame doesn’t change sharply, the difference is small between the predicted values and the real value; When the amount of data change severely, the difference between the predicted values and the real value also increases, but predicted value can reflect the change trend of real data to a certain degree.
