In a tensile pull-out test, what criteria must the anchor meet?

For an anchor to be deemed adequate in a tensile pull-out test, it is essential that it meets or exceeds the specified pull-out resistance. This criterion directly relates to the performance of the anchor in practical applications, ensuring that it can withstand the required loads without failure. Pull-out resistance is critical for maintaining the structural integrity of a project, especially in situations where significant tensile forces are expected.

Understanding this criterion is vital for verifying that the anchor will function as intended in the field. Meeting or exceeding the specified pull-out resistance guarantees that the anchor can adequately support the loads applied to it, thereby contributing to the overall safety and durability of the installation.

The other options, while they may have their own considerations in different contexts, do not address the fundamental requirement for performance under load, which is the primary concern during pull-out testing. Therefore, focusing on whether the anchor fulfills the defined pull-out resistance is essential for ensuring reliable anchorage in construction practices.
