Lately, there has been increasing demand for structural solutions and building technologies with minimalized CO₂ footprint. One way to approach the carbon neutrality is through reuse of structural components. In order to enable economic reuse of precast concrete elements, their connections must be designed to allow an effortless dismount. While dismount ability provides additional value to the structure, it cannot have a negative impact on other crucial properties of the connection. One of those properties is the load-transfer capacity. While the impact of improved demountability on the load-transfer of axial forces is negligible, the capacity of such joints to transfer shear forces can be questioned, as it is often assumed to rely on the friction generated along compressed section. This paper studies the effects of an improvement of demountability on the shear-transfer system in a bolted joint of precast concrete columns.

可拆卸预制柱连接的剪切试验

最近，对具有最小化 CO _{2 的}结构解决方案和建筑技术的需求不断增加脚印。实现碳中和的一种方法是重复使用结构部件。为了能够经济地重复使用预制混凝土构件，它们的连接必须设计成可以轻松拆卸。虽然拆卸能力为结构提供了额外的价值，但它不会对连接的其他关键特性产生负面影响。这些特性之一是负载转移能力。虽然改进的可拆卸性对轴向力的载荷传递的影响可以忽略不计，但这种接头传递剪切力的能力可能会受到质疑，因为通常假设它依赖于沿压缩截面产生的摩擦力。本文研究了可拆卸性的改进对预制混凝土柱螺栓连接中剪切传递系统的影响。
