Jointing Principles in AMC—Part 1: Design and Preparation of Dry Joints
Round 1
Reviewer 1 Report
The authors presented a very interesting problem for performing dry connections in prefabricated elements. The work is prepared at a very high level. A few comments and suggestions can be introduced:
1) Page 10, first paragraph: Fig. 7 should be referenced instead of Fig. 9,
2) Too little information about the practical application of this type of connections. Are there practical applications available?
3) Based on a very detailed and multi-criteria rating, the authors rated the highest triangular and saw tooth joints (50 and 49 scores). These are one-way shaped and straight line connections. They are the simplest performed and they are best suited to shearing forces. Connections between prefabricated elements are rarely designed for transferring stretching forces and there is no problem with the pressure forces. On the other hand, dovetail and fungal connections have been the worst rated. They are probably the most difficult performed due to concave surfaces and they are not suitable for connection of prefabricated elements. Transferring tensile forces through plane concrete without reinforcement is too risky. Perhaps adding such conclusions would be sensible.

Reviewer 2 Report
In this paper, the authors proposed an evaluation criterion for 3D-printed-concrete dry joints, which is useful for fast assembly of 3D printed component. However, there are some unclear information and the structure of the paper is not well organized. And there are many sentences hard to understand. The reviewer believes that this manuscript needs a major revision before it can be published
