Finite element analysis of reinforced concrete shear walls
… study the cyclic response of slender, reinforced concrete shear walls. Material models which represent the cyclic response of concrete and reinforcing steel in shear walls were developed in this investigation. These material models were verified both at the element and structural levels; the …

Ultra-High Performance Concrete Shear Walls in Tall Buildings
… the implications of using ultra-high performance concrete (UHPC) for shear walls in tall buildings considering structural efficiency and environmental sustainability. The Lattice Discrete Particle Model (LDPM) was used to simulate the response to failure of concrete shear walls without web steel …

Seismic retrofitting of the Ste-Justine Hospital in Montreal
… exceeds 65,000m², and none of the buildings have shear walls or bracing. The engineers have apparently been counting on the frame behavior of the continuous reinforced concrete structure to resist lateral forces. In their current conditions, the existing buildings do not meet the actual code …

Modelling of debonding mechanisms in externally bonded FRP sheets in RC shear walls for earthquake resistance
… the hysteresis response behaviour of reinforced concrete shear walls repaired or strengthened with externally boned FRP sheets under the reversed cyclic loading of earthquakes. The proposed computer model can accurately simulate the IC debonding mechanism under the two-dimensional stress state of …

Multi-objective optimization of vertically mixed lateral systems
… i.e. moment frames, steel cross bracings and concrete shear walls are utilized at varying elevations of the building to determine an optimal set of results. Besides analyzing structural optimality, the MATLAB algorithm developed as a part of this research paper also evaluates each system for …

Shear Behavior of Reinforced Concrete Beams and Prestressed Concrete Beams
… the last decades, developments in high-strength concrete materials are rapid, but codes of practice still limits the concrete compressive strength in design of concrete structures due to a lack of experimental research data. As an effort to overcome the limitation to the use of high strength …

Computational Investigation of Tunable Steel Plate Shear Walls for Improved Seismic Resistance
Steel plate shear walls (SPSWs) are popular lateral force resisting systems whose practical applications range from high seismic regions to medium and low seismic areas and wind load applications. The factors which make SPSW attractive include its energy dissipation capacity, excellent ductility, …

Determination of the Modal Parameters of a Five Story Reinforced Concrete Structure Using Ultra-Low Level Excitation and Computational Analysis
… San Luis Obispo, a five-story reinforced concrete shear wall structure. The specific testing procedure used has been verified to produce accurate results in smaller buildings, but the Kennedy Library represents the most massive subject structure. Other characteristics of this structure …

Dynamic analysis of concrete coupled wall structures : a parametric study
Concrete coupled wall structure is a system that can efficiently dissipate energy under the effect of lateral loads. It has been widely used in medium height buildings for several decades. While researchers have conducted both experimental and analytical investigations in order to improve the …

Nonlinear three-dimensional behavior of shear-wall dominant reinforced concrete building structures
The behavior of shear-wall dominant, low-rise, multistory reinforced concrete shear-wall dominant building structures commonly built in Chile, Japan, Italy and Middle East countries are investigated. Because there are no beams or columns and the slab and wall thickness are approximately equal, …

Inelastic Dynamic Behavior And Design Of Hybrid Coupled Wall Systems
… beams are used to couple two or more reinforced concrete shear walls in series, can be designed to have these attributes and therefore have the potential to deliver good performance under severe seismic loading. This research presents an investigation of the seismic behavior of this type of …

Experimental assessment of the mechanical behavior of immersion joints and a seismic mitigation method in immersed tunnels
… rubber seal, the secondary rubber seal, the shear keys, the steel shell and the pre-stressing cables. Such a complex configuration leads to difficulties to investigate the behavior of the joint. To have a comprehensive understanding of that, an experimental investigation on the joint …

Shear Behaviour in Slender Reinforced Concrete Beams with and without Transverse Reinforcement
This study investigates shear crack behaviour in slender reinforced concrete (RC) beams, focusing on the critical shear crack (CSC) geometry and its impact on crack kinematics and shear transfer mechanisms. Existing models often oversimplify CSC shape assumptions, potentially leading to …

Impact of cross section, web reinforcement and load history on the seismic performance of slender concrete walls
Many reinforced concrete buildings in seismic regions employ reinforced concrete shear walls as part of the lateral force resisting system and these walls often have non-planar cross-sectional geometries. To date, the majority of experimental tests on slender concrete walls have been conducted on …
