I just had a Renaissance moment, a real eureka moment.
My friend Matt and others will say "jeez, he is only realizing that now?"
I am not a trained professional engineer or builder, but I have some experience. All my arches and vaults are semicircular or catenary curves. Vaults I build without centring, and but arches over openings with centring, as i need a wall to "glue" the bricks. Like the first arch below.
So here it is
IF I USE POINTED ARCHES (middle type) IT WILL MEAN THE LAST BRICKS WILL BE MORE VERTICAL INSTEAD OF HORIZONTAL!
Pointed arches are like the second arch above and this one below.
I see it all the time in pictures but it just dawned on me now that it will make some vaults easier, as the curve stays more vertical, hence less gravity pulling it down before the arch is closed! Jeez Matt why didnt you yell at me? Your latest WTO has pointed in it!
I see some issues as they will require greater height in arches over doors.
So my groined vaulted rooms will look like this maybe.
Which means I should be able to go horizontal course much higher
"The main advantage of the pointed arch was that it concentrated the thrust of the vault on a narrow vertical line that could be supported by the flying buttresses, a major feature of Islamic architecture and also European Gothic architecture. The pointed arch enables the reduction of the lateral thrust on foundations. It enabled architects to lighten the walls and buttresses which had to be massive to support earlier semicircular arches(endnote 2). Additionally, it resolved the difficulty of achieving level crowns in the arches of the vault allowing the vault to become suitable for any ground plan."

I mean look how steep that is!
Is this the new look on my buildings?
