Re: Glu-Lam "Bents" --> Church Sanctuary

[Subject Prev][Subject Next][Thread Prev][Thread Next]
Bill,
 
        Tutor Arch is an architectural term for a pointed arch.  Roman Arch is an architectural term for a rounded arch.
 
        A three hinged arch is an engineering term for any arch with three hinges.  GlueLam Tutor Arches for churches are usually (but not necessarily) three hinged arches.  Three hinged arches are statically determinate, which historically made them easier to analyze.
 
        A two hinged arch is an engineering term for any arch with only two hinges usually (but not necessarily) at the base on each side.  Roman Arch Quonset hut structures are usually (but again not necessarily) two hinged arches.  Two hinged arches are one degree statically indeterminate, which requires a little more engineering effort but has the advantage of economy of materials.
 
        Thus ends the gospel according to Seaint Respondent.
 
Happy New Year, Bill.
 
Regards,
 
H. Daryl Richardson

Thanks. Seems like the votes are in for ?three-hinged arch.? Of course, I like ?tudor arch? better, but how many engineer-poets can we have in a single generation?

Bill-

Do you mean "Three Hinged Arch".  See www.aitc-glulam.org , Technical Notes, TN-02 and TN-23 for details and Technical Information, Three-hinged arch tables for design information.
