Theoretical and experimental study of precast reinforced concrete walls with different openings under seismic loads

Prediction of capacity of reinforced concrete shear wall with multiple openings by using nonlinear finite element analysis

“…In the literature review, it was determined that the variables that play the most effective role on the horizontal force bearing capacity of the RC shear walls with openings are the size of the opening left in the RC shear walls, the position on the shear wall, the number of openings and the concrete compressive strength. [5][6][7][8][10][11][12][14][15][16][17][18][19] In this manner, it was decided to examine these variables in the parametric numerical analysis study. While creating finite element models, an 8-node linear brick element with reduced integration and hourglass control (C3D8R) for the shear wall, a 2-node linear beam element (B31) for the reinforcement steel, and a 4-node bilinear quadrilateral rigid element (R3D4) for the load transfer bar that performed the loading were selected in the software.…”

“…In addition, the concrete compressive strength used in the production of RC shear walls on the horizontal earthquake force bearing capacity is also an effective parameter. In the literature review, it was determined that the variables that play the most effective role on the horizontal force bearing capacity of the RC shear walls with openings are the size of the opening left in the RC shear walls, the position on the shear wall, the number of openings and the concrete compressive strength 5–8,10–12,14–19 . In this manner, it was decided to examine these variables in the parametric numerical analysis study.…”

“…Investigation on the impact of the openings left in RC shear walls on the general loaddisplacement behavior, maximum load-bearing capacities, stiffness, displacement ductility ratios, and energy dissipation capacities of the shear walls remain an essential issue in the scientific research area. [4][5][6][7][8][9][10][11][12][13][14] When the literature is examined, it is seen that a generalizable result to determine the effect of the openings in the RC shear walls, especially on the maximum bearing capacity of the shear wall, has not been reached yet.…”

“…Although there are no definite equations or methods in the regulations 1–3 of these openings required to be left in RC shear walls, and to which extent they reduce the capacities of structural members, various rules have been included to limit the negative effects of openings on the overall seismic performance of RC shear walls. Investigation on the impact of the openings left in RC shear walls on the general load–displacement behavior, maximum load‐bearing capacities, stiffness, displacement ductility ratios, and energy dissipation capacities of the shear walls remain an essential issue in the scientific research area 4–14 . When the literature is examined, it is seen that a generalizable result to determine the effect of the openings in the RC shear walls, especially on the maximum bearing capacity of the shear wall, has not been reached yet.…”

Mechanisms and Prediction Model of Load-carrying Capacity in Staggered Perforated RC Flanged Shear Walls

“…Hosseini et al (2019) studied the relationship between the eccentric distance of the perforation and failure mode in the shear wall. Dan et al (2021) conducted the theoretical and numerical analysis of the various perforation in the shear wall. And the seismic performance was discussed.…”
