In the numerical analysis of engineering problems, it is often necessary to properly model the behavior and effects of discontinuities and interfaces. The parameters of the experimental and analytical programs were the concrete compressive strength and shear span-depth ratio. Discrete and smeared ways of analysis of the bond link element were used. Effort has been given using non-linear 3D FEM program to predict the punching shear failure mechanism and the crack pattern of open sandwich slabs. Based on the analytical

With the establishment of several construction applications of FRP reinforcement, there is a need for a system to resist lateral loads induced from wind and earthquake loads in these constructions. Reinforced concrete shear walls have shown effective performance in resisting lateral loads caused by wind and earthquake loads. Therefore, shear walls are frequently used in parking garages and multi-story buildings exposed to high lateral loading. This research involved testing a shear wall totally

Fiber-reinforced polymer (FRP) materials have proven their effectiveness as an alternative reinforcement for concrete structures in severe environmental conditions. Many studies have investigated the flexural and shear behaviors of FRP-reinforced concrete beams and slabs. Limited research, however, has gone into investigating the behavior of internally reinforced FRP concrete columns. This paper reports the experimental investigation of the compressive performance of concrete columns reinforced

Few studies are available on members reinforced internally with fiber-reinforced polymer (FRP) bars and subjected to compressive axial load; therefore, the behavior of FRP internally reinforced concrete columns has not been well established. In this paper, experimental results of 23 nearly full-scale square concrete columns reinforced transversally with glass FRP (GFRP) and carbon FRP (CFRP) ties, and longitudinally with GFRP, CFRP, and steel bars, and subjected to concentric monotonic axial compression

The ACI and CSA design codes offer no unified method for evaluating the deformability of fiber-reinforced polymer (FRP) reinforced-concrete (RC) structures, although numerous experimental results for such elements are available. This study discusses the methods for quantifying the deformability in FRP-RC structures. The methods were assessed based on the experimental results of four full-scale RC shear walls: three reinforced with FRP bars and one with steel bars

The test results on shear walls with glass fiber-reinforced polymer (GFRP) reinforcement have proven the applicability of such structural members in resisting lateral loads and strongly suggested the necessity of proposing a design procedure for them. The elastic and inelastic deformations were identified and suggestions for appropriate definitions provided. The force modification factor Rd was estimated based on the idealized curve of the tested shear walls. The virtual plastic hinge lp for GFRP-reinforced walls was described

Effort has been given using non-linear 3D FEM program to predict the punching shear failure mechanism and its strength of steel-concrete open sandwich slabs with stud. In the analysis the stud is modeled by link element whose constitutive model is derived from the authors' experimental study. The results show very good agreement between the analytical and experimental values. Punching shear failure phenomena is carefully examined in the analysis observing predicted concrete cracking pattern and concrete crushing
