Abstract:
Design and construction of special shear walls requires consideration of several factors including the magnitude and direction of lateral loads, height and aspect ratio of the concrete walls, wall location, and material properties. Recent research has shown that the ACI 318-19 required boundary transverse reinforcement for rigid wall flexible diaphragm buildings may be too restrictive leading to unnecessary construction costs. This is quite common for tilt-up construction where concrete shear walls are tilt-up panels, and the roof is constructed by light wood panels; therefore, more detailed assessment of the ACI 318 design requirements is warranted to determine if relaxing requirements for this type of construction is possible or if alternative requirements should be developed. To address this need, studies based on available research and appropriate models are used to propose new, more cost-effective, detailing requirements that will greatly improve the safety and performance of tilt-up buildings while also providing cost-effective and efficient construction solutions.
