“…Based on the experimental result; the stirrups increased the joint shear capacity and restrained the deformations. As the stirrups percentage increase the crack load increase and the crack appear in a late stages in the back face of the beamcolumn joint as stated by Marthong et al [12].…”

The present research investigates experimentally the behavior of the reinforced concrete BCJ joint under quasi-static cyclic loads for different mount of the shear reinforcement. The specimen consisted of two columns and two beams; one is a free end and the other is a fixed end. The shear reinforcement of the joint was 1Ø6 mm, 2Ø6 mm, and 3Ø6 mm. Three specimens were tested under quasi-static cyclic loading up to failure. The cracking loads, ultimate loads, deflection of the free end of the loaded beam, crack patterns and failure modes for BCJ were recorded and analyzed at each cycle. Also energy dissipation and stiffness degradation of all specimens were discussed. The experimental result indicates that the increase in the amount of the stirrups of the joint transmitted the main failure into the column far away from the joint. The increase in the amount of joint stirrups enhanced the joint capacity. The stirrups are most effective in is the middle third part of the BCJ than others two parts.

“…Experiments on structural elements under fatigue loading representative of traffic loads on bridges are not very common. The influence of cycles of loads that represent seismic actions has been studied experimentally (El-Bahy et al, 1999;Mander et al, 1994;Manfredi and Pecce, 1997;Marthong et al, 2016;Thomson et al, 1998). Such experiments use loads that result in stress reversals, a situation which is different from what happens in a bridge subjected to repeated traffic loads (Elfgren, 2015;Forrest et al, 2010;Schlafli and Bruhwiler, 1998).…”

“…Nevertheless, the specimens designed according to the Indian Standards represent higher energy dissipation at a preset drift ratio. Marthong et al [15] studied the in uence of di erent frequencies' cyclic excitations on the seismic behavior of external RC beam-column specimens with typical deficiencies. e results indicate that the influencing effect of the loading rate is significant in beam-column joints with beam weak in flexure, while the effect is not so significant in the other joints.…”

The effect of a cast-in-place slab on the beam-column joint at beam ends in reinforced concrete (RC) structures under earthquake attacks has not been fully understood, and therefore, it is not manifestly addressed to some of the design criteria or specifications. Consequently, the contribution of slab to the seismic resistance of structures is often ignored or just included in an approximate manner. In this study, the experiment of two 1/2-scaled exterior beam-column joints without slabs and three 1/2-scaled joints with slabs under the combination of quasi-static repeated cyclic loading and constant axial force was carried out to investigate the effect of the cast-in-place slab on the seismic performance of exterior beam-column joints. The results show that for specimens EBCJ1 and EBCJ2 without slab, the decline was approximately 5%, while for specimens EBCSJ1 and EBCSJ3, the decline in the load is obvious and approximately more than 10%. For specimen EBCSJ2, which exhibited a slightly different behavior in the hysteresis curves, the maximum carrying capacity reached at the displacement of 70 mm during the first cycle. The cast-in-place slab has different effects on the failure mechanism and load transfer mechanism of the exterior beam-column joint, which depends on the column-beam moment strength ratio in the loading protocol. The slab has a positive effect on the energy dissipation capacity of the joint but has a negative effect on the load carrying capacity. In addition, finite element (FE) analysis of the tested specimens was conducted. The FE numerical models were established based on the construction information and loading conditions from the experiment and then validated by comparing them with the experimental observation.
