Abstract. Several numbers of strength models of FRP-confined circular concrete columns have been published by several researchers. In this study, strength models were proposed based on experimental data. Nine existing FRP-confined strength models of column confinement were reviewed in this study and two forms of strength models of FRP-confined circular concrete columns were proposed. The models were proposed based on different number of experimental data collected from literature. Based on the number of experimental data, i.e. 64-, 106-, 156- and 192-, the strength models were developed. The performance of the existing and the proposed strength models were evaluated and compared. The evaluation results showed that the strength models proposed based on 192-data had the best performance among other models proposed with smaller number of data. It was also shown that the proposed strength models had better performance than the existing strength models.

Introduction

Strengthening of reinforced concrete structures has become very important and has been accepted in the world of construction along with that many structures of civil buildings suffered damage (deterioration). The strengthening method is more advantageous to be done when compared to the method of replacing or rebuilding of the structures. There are several conditions that make reinforced concrete structures require strengthening or retrofitting for example cracks, corrosion, damages due to earthquake loads, the imperfection of the design, and increment of service load. For concrete column structures, strengthening by wrapping columns with certain materials (method of jacketing) has become a popular method, where it especially has been done using fiber reinforced polymer (FRP). FRP has several advantages in mechanical properties such as high strength, high stiffness and durability, low density, corrosion resistance, low thermal coefficient and high strength to weight ratio [1]. FRP types that commonly used as structural strengthening materials are Glass, Carbon, Aramid and Kevlar fiber.

Some experimental tests on concrete columns with circular cross section have been conducted by several researchers [2,3,4,5,6]. The results of such studies showed that strengthening concrete columns with FRP increased the strength and performance of the columns.

(12)

Methodology

This study was conducted by reviewing and analyzing some existing strength models of confined circular concrete columns. Several researchers have published strength models to determine the axial compressive capacity of circular concrete columns confined with FRP sheets, such as Newman and Newman [13], Fardis and Khalili [7], Mirmiran and Shahawy [14], Miyauchi et al. [8], Toutanji [9], Lam and Teng [10], Lam and Teng [11], and Matthys et al. [12]. The strength models were formulated based on the testing results having various parameters and different number of specimens.

The majority of the available existing models to determine the compressive strength of FRP-confined circular concrete columns are based on the confinement model derived by Richart et al. [15] using Eq. (1).

where, fcc' and fco' are the compressive strength of confined and unconfined concrete, respectively;

1

k is the coefficient of confinement effectiveness, and f is the lateral confining pressure. The l

lateral confining pressure provided by the FRP jacket is expressed in Eq. 2 as:

d t f

fl =2 f f (2) where, f is the rupture tensile strength of FRP; f t is the thickness of FRP; and d is the diameter f

of the confined concrete.

Lateral confining pressure of FRP jacket on the circular concrete section can be illustrated as in Fig. 1.

Fig. 1. Confining pressure of FRP jacket

Some of the existing strength models for FRP-confined circular concrete where had been published in the literatures were reviewed and analyzed in this study, including:

(13)

- Model of Fardis and Khalili [7]

- Model of Mirmiran and Shahawy [14]

'

where, fl,a is the actual confining pressure and can be calculated as:

d average value of strain efficiency factor (εh,rup εf ) of 0.63 was obtained for a different type of FRP, where εf is the ultimate tensile strain of FRP from coupon tests.

- Model of Matthys et al. [12]

(14)

and some other models had the following form:

where α is the coefficient of the lateral confinement ratio.

In formulating Eqs. (12) and (13) which is determining the values of k1 and α, analysis using

optimization methods was done. Optimization was done by using a statistical indicator i.e. the criteria of Sum of squares error (SSE), which was formulated as follows [16]:

(

) (

)

The analysis to formulate the strength models was done based on different number of experimental data. The data were grouped according to the research development or based on the year of publication. The data were summarized as follows and in detailed were shown in Table 1.

- 1994 to 1999 : 64 data - 1994 to 2001 : 106 data - 1994 to 2007 : 156 data - 1994 to 2012 : 192 data

Results and Discussion

Strength Models Proposed Using Different Number of Experimental Results

Analysis to determine the value k1 of the Eq. 12 was performed by means of optimization

process to obtain the smallest value of SSE. Optimization was done for each number of testing data

and the results were shown in Fig. 2.

Fig. 2. Performance of strength models in a form of Eq. 12 with different number of testing data

It can be seen from Fig. 2 that the larger the number of experimental data resulted in a greater value of SSE. The model based on 64 testing data had the smallest value of SSE which was about

4.90. Meanwhile, the greatest value of SSE was obtained from the strength model proposed based on

192 testing data which was about 12.63.

Furthermore, analysis to determine the value k1 and α of the Eq. 13 was performed by similar

method to obtain the smallest value of SSE. Optimization was also done for each number of

experimental data and the results were shown in Fig. 3.

Fig. 3. Performance of strength models in a form of Eq. 13 with different number of testing data

Similar condition as in Fig. 2 was observed from Fig. 3 as well. The larger the number of testing data resulted in a greater value of SSE. The model based on 64 testing data had the smallest value of

SSE which was about 2.87. Meanwhile, the greatest value of SSE was obtained from the strength

model proposed based on 192 testing data which was about 10.61. Until this stage, no optimum

(16)

Verification of the Proposed Strength Models

In order to define the proposed strength model which gives the best performance, i.e. the smallest value of SSE, all strength models with corresponding coefficients k1 and α were evaluated

using 192 data of experimental results. The result of the evaluation showed that the strength model proposed using 192 experimental data had the best performance with the values of SSE of 12.63 and

10.61, respectively for models having the form of Eqs. 12 and 13. The evaluation results are completely shown in Figs. 4 and 5.

Fig. 4. Performance of strength models having a form of Eq. 12

Fig. 5. Performance of strength models having a form of Eq. 13

Based on the aforementioned evaluation results, the following equations were proposed as the strength models to determine the axial compressive capacity of FRP-confined circular concrete columns:

12.2 12.4 12.6 12.8 13.0 13.2

2.22 (192 data)

10.0 10.5 11.0 11.5 12.0

(17)

When compared with the existing strength models and analysed using 192 experimental data, again the strength models proposed in this study showed the best performance, as shown in Fig. 6.

Fig. 6. Performance comparison between proposed and existing strength models

Conclusions

Strength models of FRP-confined circular concrete columns under axial compressive loads were proposed in this study based on different number of experimental data. The analysis results showed that the value of confinement effectiveness k1 varies between 2.10 to 2.22 and the value of

coefficient of lateral confining ratio α varies between 0.81 to 0.89. The strength models that proposed in this study using 192 experimental data had the best performance. The analysis also shows the proposed strength models have better performance than those of the existing strength models.

Effect of transverse steel ratio on overall torque–twist behavior: a circular column axial compression=2 MPa; b square column axial compressive stress=1 MPa Downloaded from

Compressive strength testing of concrete using WPC and grey cement was carried out at ages: 3, 7, 14, 21, and 28 days.. The compressive strength of concrete using WPC is higher than

The polypropylene content was taken as 1% where an increase in compressive strength and split tensile strength can occur by adding a fiber content of 1% of the total volume of concrete
