“…The paper by [ 17 ] examines the effect of PBO (P-phenylene benzobisoxazole)–FRCM (fabric-reinforced cementitious matrix) reinforcement on the stiffness of eccentrically compressed reinforced concrete columns. Reinforcement with FRCM consists of bonding composite meshes to the concrete substrate by means of mineral mortar.…”

This issue is proposed and organized as a means to present recent developments in the field of testing of materials in civil engineering. For this reason, the articles highlighted in this issue should relate to different aspects of testing of different materials in civil engineering, from building materials and elements to building structures. The current trend in the development of materials testing in civil engineering is mainly concerned with the detection of flaws and defects in elements and structures using destructive, semi-destructive, and nondestructive testing. The trend, as in medicine, is toward designing test equipment that allows one to obtain a picture of the inside of the tested element and materials. Very interesting results with significance for building practices of testing of materials and elements in civil engineering were obtained.

“…The FRCM method provided good results for the retrofitting of RC elements to obtain sufficient ultimate capacity, ductility, and stiffness. Although the FRCM method exhibits good results in strengthening/retrofitting, the effect on the ultimate capacity and ductility decreases when the number of FRCM layers increases [16][17][18][19][31][32][33][34][35][36]. The failure of the FRCM is caused by the slippage of the fibre inside the cementitious matrices rather than by fibre rupture.…”

This paper presents an analytical and experimental examination of reinforced concrete (RC) columns strengthened with a combined system of fibre-reinforced cementitious material (FRCM) and externally bonded fibre-reinforced plastics (EB-FRP). The proposed technique makes use of these advantages in enhancing the strength and minimising the premature failure of RC columns. Seven square RC columns were cast: one control column, four FRCM-strengthened columns, and two hybrid-strengthened columns. Two fibres, namely, carbon and glass fibres, were used. The columns were tested under an axial compression load in a loading frame. The ultimate strength, load vs. deformation, failure, and ductility were discussed to examine the failure and strengthening behaviour. The proposed method provided a higher confinement effect and increased capacity with fewer FRCM with EB-FRP than the other methods. Analytical predictions of the peak load were made and correlated with the experimental results.

“…Improper estimation of member stiffness leads to an inaccurate evaluation of structural response quantities. Some of the important factors that are affected by member stiffness are the period of the structure, deformation demands, distribution of loads, and yield displacement [ 1 , 2 , 3 , 4 , 5 , 6 ]. Tensile strain developed in the section reduces the effective area of the RC section, and it is called a cracked section.…”

A Prediction Model for the Calculation of Effective Stiffness Ratios of Reinforced Concrete Columns

et al. 2021

Nonlinear dynamic analyses of reinforced concrete (RC) frame buildings require the use of effective stiffness of members to capture the effect of cracked section stiffness. In the design codes and practices, the effective stiffness of RC sections is given as an empirical fraction of the gross stiffness. However, a more precise estimation of the effective stiffness is important as it affects the distribution of forces and various demands and response parameters in nonlinear dynamic analyses. In this study, an evolutionary computation method called gene expression programming (GEP) was used to predict the effective stiffness ratios of RC columns. Constitutive relationships were obtained by correlating the effective stiffness ratio with the four mechanical and geometrical parameters. The model was developed using a database of 226 samples of nonlinear dynamic analysis results collected from another study by the author. Subsequent parametric and sensitivity analyses were performed and the trends of the results were confirmed. The results indicate that the GEP model provides precise estimations of the effective stiffness ratios of the RC frames.
