Rolling shear refers to the shear forces that occur between the layers of Cross-Laminated Timber (CLT) as they interact under load. This type of shear is particularly critical in CLT construction, where multiple layers of timber are stacked perpendicular to one another to enhance structural stability and strength.
The grain direction plays a vital role in resisting rolling shear. In CLT panels, alternating the grain direction of each layer helps to distribute shear forces more evenly and reduces the risk of shear failure. When the grain is properly aligned, the timber layers can effectively resist the sliding forces that cause this problem, ensuring the integrity and durability of the structure.
Effective management of rolling shear involves meticulous design and detailing to ensure that connections between layers are robust and that the overall panel configuration maximizes shear resistance. By prioritizing grain direction in the design phase, engineers can significantly enhance the performance of CLT panels, making it a fundamental consideration in sustainable timber engineering.
At Ergodomus, we utilize advanced analytical tools to identify potential rolling shear issues and implement necessary reinforcements. Our expertise ensures that CLT structures not only meet but exceed structural integrity standards, providing safe and durable timber buildings. Through comprehensive clash detections and precise detailing, we address it proactively, ensuring that every timber element performs optimally under various loads.
