“…Fayed et al [18] investigated the behaviour of 3D constructions that included BCCs. The behaviour of structural components was examined in studies [19][20][21][22][23][24][25][26][27][28][29][30][31][32][33][34][35][36][37].…”

An experimental investigation studied performance of Scorner beam-column connection (BCC) under cyclic loading. Each BCC consisted of upper, lower column and two beams; one of them was free end (A) while the other was fixed end (B). The cyclic loading was applied on the end of beam (A) while the beam (B) was unloaded and subjected to torsion stresses due to fixation. Two variables were investigated. The first is the eccentricity of the beam about column edge while the second is the effect of stirrup joint configuration on BCC under cyclic loading. All BCCs were tested under reversible fourteen cycles. The vertical displacement at the free end of the beam (A), horizontal sway at mid height of the column, crack and ultimate loads were observed in details at each cycle. The findings noticed that the increase of stirrup length in the connection decreased the deflection at the same level of the load. The ultimate load of specimen, which was shifted by 25mm, was less than the ultimate load of specimen, without shift, by 24%.When the joint stirrup was extended outside the column core by 50 mm in specimen Sp2, the capacity of the connection increased.

The most current used technology for strengthening reinforced concrete (RC) beams is aluminum plate (AP). The use of AP to strengthen RC beams was investigated in this study. The experimental program included twenty-five RC beams (1/5 scale), with 14 and 11 beams strengthened in shear and flexure, respectively. All beams were the same size. All beams were subjected to four-point bending flexural tests. Various AP-based strengthening approaches were used. To improve shear strength, APs were glued vertically, inclined by 45 0 degrees, diagonally, and horizontally on the beams' sides (SS). The effect of AP pitch, height, and amount was investigated. APs of varying length, number, and pitch were agglutinated at the beam soffits to improve flexure strength (FS). All APs improved shear and flexure capabilities, while some of them modified the failure mode.

“…Generally, the composite concrete material can significantly affect the major behavior of stiff mode into the ductile one with the presence of steel bars or use new generation of concrete [19][20][21][22]. Also, a comperhensive research have been carried out for the concrete structures influenced by ambient conditions [23][24][25][26].…”

In this paper, the time-displacement response of Reinforced Concrete (RC) slab subjected to impact loading was investigated through the Finite Element (FE) modeling in which the Concrete Damage Plasticity (CDP) model was employed. The main parameters of the current study were the thickness of the slab (100, 150, 200, and 250 mm), the area of tension reinforcement, and the area of compression reinforcement. Results showed that the slab thickness and the tension reinforcement area significantly influenced the time-displacement response of the RC slab under impact loading. On the other hand, the compression reinforcement area showed almost no significant effect on the time-displacement response.
