    USING GRAVITY FOR BUILDING ARCHES LIKE THE ANCIENT ROMAN BUILDERS DID ►
    The Arch-lock system uses gravity for joinery! The precast concrete blocks are used for building the strong free-standing structures like tunnels, overpasses or storage sheds without the need for mortar.

    #6 Thank you, Lada, for your detailed answer. My questions were more than idle curiosity, as I have professional interest in the science of string materials and the associated engineering of structures that take best advantage of those modern materials. But the fact is one cannot fully appreciate strong materials and engineering for minimum weight unless one has an appreciation for structures such as the Roman arch. Cheers!

    #4 (Sequel to my previous answer)
    Yes, we are in the age of the strong materials such as steel and prestressed concrete that allow construction of much larger arches than the ancient Romans did. But the fact is that these ancient arch bridges and aqueducts still standing today and they survived despite seismic activities throughout the centuries, which many modern buildings didn't.
    We can't build arches like that anymore because the method of construction is both material and labour intensive. The massive falsework was required to support all parts of the structure, which has no stability prior to the insertion of the keystone on the top of an arch.
    That's why I see many benefits of this modern and improving approach to the true Roman arch. 1.) This method eliminates falsework. 2,) Interlocking design holds the precast concrete voussoirs together during and after assembly and eliminates the need for mortar.
    I read about some project in Canada where the Arch-Lock system would be used, as a low-cost vaulted tunnel on the railway line that would allow the construction of the highway directly over.

    As for bonding the wedge-shaped stones together, the Romans had used the slow setting mortar and some kind of shimming to overcome dimensional irregularities of cut stone voussoirs.

    #4 Phil, first, I admire you as a commenter because your questions always provoke further engagement with the post. I'm glad you find this topic interesting. I'm also glad that there are people (though, very few) who will engage in such "engineering" topics, commenting on its core. :-)
    This is the first part of my response. I'm writing this while drinking my morning coffee before going to work. I'll continue in the afternoon. Regards

    #3 The Roman arch is, of course, fascinating, being able as it is to transfer all the loads in such a way as to hold itself together and stable, as well a support external loading at the same time. But, here are a couple of questions I still have:

    1) Does bonding the component stones together have any beneficial effect on the arch's ability to withstand loading? Has anyone ever experimented with that?

    2) In this age of the science of strong materials and the techniques of creating structures that dispose strength-contirbuting cross-section where it does the most work underloads, outmode the true arch which is a pure compression structure?

    #1 Phil, thanks for stopping by and commenting. :-)
    I've been interested in Ancient Roman architecture for a long time. The Roman arch has had a lasting impact on architecture all the way to the present time.
    Both the angle and the number of wedge-shaped stones (voussoirs) have an effect on the strength and stability of an arch. For the semicircular arch, it seems that an "ideal" angle is when 180 degrees divides into 11 sectors, at about 16 degrees each.
    It is the number of concrete wedge-shaped elements in the post picture.

    there are roman constructions over 2000 y.o. and they are prefect. Most of new/current constructions will never last for the same number of years.

    Interesting, Lada. I've always wondered if there's an "ideal" number of stones for the arch or an ideal angle for the shape?

    Great article John! Thanks for sharing. Prefabrication is such a viable solution in addressing labor shortages and on-site construction challenges. It will be interesting to see if health care facilities begin to use repeatable component design to minimize the redesign that is common on each new project.

    I have sat in on progress meetings (plant shutdowns) with over 50 attendees. Some of these meetings ran over 1 hour. The cost of a meeting that size is grotesque. There are better ways to communicate to large teams than lengthy meetings. The key is finding a medium that works well and engages colleagues regularly. Great article!
