Catenary Arches
A catenary arch is a type of architectural arch that follows an inverted catenary curve. The catenary curve has been employed in buildings since ancient times. It forms an underlying principle to the overall system of vaults and buttresses in stone vaulted Gothic cathedrals and in Renaissance domes. It is not a parabolic arch. In history The 17th-century scientist Robert Hooke wrote: "''Ut pendet continuum flexile, sic stabit contiguum rigidum inversum''", or, "As hangs a flexible cable so, inverted, stand the touching pieces of an arch." A note written by Thomas Jefferson in 1788 reads, "I have lately received from Italy a treatise on the equilibrium of arches, by the Abbé Mascheroni. It appears to be a very scientific work. I have not yet had time to engage in it; but I find that the conclusions of his demonstrations are, that every part of the catenary is in perfect equilibrium". Structural properties Architecturally, a catenary arch has the ability to withstand the we ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Beehive Home
A beehive house is a building made from a circle of stones topped with a domed roof. The name comes from the similarity in shape to a straw beehive. Occurrences The ancient Bantu used this type of house, which was made with mud, poles, and cow dung. Early European settlers in the Karoo region of South Africa built similar structures known as corbelled houses. These white-washed structures are described as coursed rubble on a circular plan, with each successive course smaller and slightly corbelled over the course below so that a conical shape is achieved as each course is completed. Beehive houses are some of the oldest known structures in Ireland and Scotland, dating from as far back as around 2000 BC. Bee houses have also been built in the Italian peninsula, with some still being built as late as the 19th century in Apulia (south-eastern Italy). In Southern Italy, these houses are called '' trulli'' while its prehistoric Sardinian versions were referred to as ''nuraghi'' ...

Christopher Wren
Sir Christopher Wren PRS FRS (; – ) was one of the most highly acclaimed English architects in history, as well as an anatomist, astronomer, geometer, and mathematician-physicist. He was accorded responsibility for rebuilding 52 churches in the City of London after the Great Fire in 1666, including what is regarded as his masterpiece, St Paul's Cathedral, on Ludgate Hill, completed in 1710. The principal creative responsibility for a number of the churches is now more commonly attributed to others in his office, especially Nicholas Hawksmoor. Other notable buildings by Wren include the Royal Hospital Chelsea, the Old Royal Naval College, Greenwich, and the south front of Hampton Court Palace.
