Common Threads Structural Issues in Historic Buildings By Craig M. Bennett, Jr., P.E. Charleston, South Carolina is blessed with historic structures. Eighteenth and nineteenth century houses, churches and civic buildings adorn every block. The city has ® interesting challenges for the structural engineer… the east coast’s largest earthquake, hurricanes, city-wide fires and poor soils have put buildings and their designers to the test. Because the primary structural materials found here, soil, masonry, timber and iron, are the same as those used everywhere over the last three centuries, struc- tural issues common to buildings in Charleston are found in historic buildings all over the nation. Buildings move due to consolidation of soils; masonry cracks; lime leaches out of mortar; timber creeps under stress and rots when faced with water intrusion and iron corrodes. The only threat not severe here is a regular freeze- thaw cycle.

Geometric Proportioning Strategies in Gothic Architectural Design Robert Bork*
$UFKLWHFWXUDO Bork, R 2014 Dynamic Unfolding and the Conventions of Procedure: Geometric +LVWRULHV Proportioning Strategies in Gothic Architectural Design. Architectural Histories, 2(1): 14, pp. 1-20, DOI: http://dx.doi.org/10.5334/ah.bq RESEARCH ARTICLE Dynamic Unfolding and the Conventions of Procedure: Geometric Proportioning Strategies in Gothic Architectural Design Robert Bork* This essay explores the proportioning strategies used by Gothic architects. It argues that Gothic design practice involved conventions of procedure, governing the dynamic unfolding of successive geometrical steps. Because this procedure proves difficult to capture in words, and because it produces forms with a qualitatively different kind of architectural order than the more familiar conventions of classical design, which govern the proportions of the final building rather than the logic of the steps used in creating it, Gothic design practice has been widely misunderstood since the Renaissance. Although some authors in the nineteenth and twentieth centuries attempted to sympathetically explain Gothic geometry, much of this work has been dismissed as unreliable, especially in the influential work of Konrad Hecht. This essay seeks to put the study of Gothic proportion onto a new and firmer foundation, by using computer-aided design software to analyze the geometry of carefully measured buildings and original design drawings. Examples under consideration include the parish church towers of Ulm and Freiburg, and the cross sections of the cathedrals of Reims, Prague, and Clermont-Ferrand, and of the Cistercian church at Altenberg.

Jan Lewandoski Restoration and Traditional Building 92 Old Pasture Rd. Greensboro Bend , Vermont 05842 802-533-2561; 802-274-4318 [email protected] May 7, 2020 The Granville Town Hall, Granville Vermont A Preservation Trust of Vermont Technical Assistance Survey The Granville Town Hall is a tall 2-story, white, clapboarded structure located on the west side of Rt. 100 at the center of Town. It was first built as a church in 1871. It is currently attached to the Town Offices, which are located in the Town’s 1857 schoolhouse. The Town Hall probably started life sitting on a stone foundation on the ground. At a later date the church was lifted and had the current first floor added beneath it. The doorway appears to be of the original period of the church (1871), and to have been relocated to the new lower story. The original tower may have been only the first square section, but at some later date the second square and spire were likely added. I base this observation on fact that the second square section of the tower, and the spire, don’t start within the first section as is usually done (telescoping), but just sit on top of it. The architectural style is vernacular Greek Revival. Characteristic of this are the wide pilasters, closed pediment, and wide double frieze. There is an interesting projection, reflecting the position of the tower or a porch for the doorway, on the middle of the front wall. This is seen occasionally on Vermont churches. The Town Hall is of timber frame construction, spruce and hemlock, and measures about 36 x 48 in plan. -
Architecture of the Cabildo
Architecture of the Cabildo The Cabildo in New Orleans is one of the most historically significant buildings in Louisiana. It was the seat of Spanish colonial government, the site of the Louisiana Purchase transfer ceremony, and home of the Louisiana Supreme Court. It is now part of the Louisiana State Museum. Learn more about the architectural features of this iconic building! Architecture The Cabildo was built 1794-1799 under Spanish rule. It was designed by Gilberto Guillemard in the classical style, which is modelled on the architecture of ancient Greece and Rome. This style was common for eighteenth-century Spanish government buildings and has been used throughout history to convey power and wealth. The wrought-iron balcony railings were created by Marcelino Hernandez, an immigrant from the Canary Islands. The Spanish coat of arms in the pediment was replaced with a patriotic sculpture of an American bald eagle in 1821, a few years after Louisiana became a state, sculpted by Italian artist Pietro Cardelli. In 1847, a third floor with a mansard roof and cupola replaced the original flat roof. This popular French roof style was added in part to match the planned scale of the Pontalba apartment buildings on Jackson Square, which were begun in 1849. These features form an impressive façade that reflect changing influences in New Orleans over time.

WHY YOU ASK? ST MARY’S Because This Will Be ‘NO MORE’ If the Spire Is Not Repaired URGENTLY! CHURCH BROOMFIELD This Is NO Cliche! This Is SERIOUS!
DO YOU LOVE TO HEAR THE BELLS RING? DO YOU LOVE THE HERITAGE OF OUR VILLAGE CHURCH? DO YOU LOVE THAT THIS IS ONE OF ‘FEW’ CHURCHES ‘LEFT’ WITH A ROUND TOWER? DO YOU LOVE THE SCENIC VIEWS OF OUR CHURCH IN ALL SEASONS? DO YOU LOVE HAVING A RARE ‘CHURCH BUILDING’ IN OUR VILLAGE? WHY YOU ASK? ST MARY’S Because this will be ‘NO MORE’ if the Spire is not repaired URGENTLY! CHURCH BROOMFIELD This is NO cliche! This is SERIOUS! If you love your church, your village, your community – PLEASE HELP? Please see attached for the ‘worrying’ facts and the financial status….. DO YOU LOVE TO HEAR THE BELLS RING? Did you know the bells have rung from as early as 1482? DO YOU LOVE THE HERITAGE OF OUR CHURCH? Did you know that the spire dates from the 15th century and ‘2 of our 6’ bells date from 1613 and 1580? DO YOU LOVE A RARITY? Did you know there is a ‘Fresco’ painting in the tower? The ‘only’ modern/20th century Fresco painting in England? This was painted by the famous artist Rosemary Rutherford in 1942. The painting is of ‘Christ stilling the storm’. It was painted on wet plaster during a break from the war. DO YOU LOVE THAT WE ARE ONE OF ‘FEW’ CHURCHES LEFT WITH A ROUND TOWER? Did you know there are only 6 Round Tower Churches left in Essex including ours? DO YOU LOVE THE PHOTOS TAKEN OF OUR CHURCH IN ALL SEASONS? The winter mornings, the sunrise, the sunsets, the springtime, the summer weddings, the family occasions! All of the above will just be ‘HISTORY’ if we FAIL to repair the SPIRE ROOF! I know you hear many times that churches need funds for roof repairs but this REALLY is the case! The Spire roof is so BADLY damaged from water ingress that the timbers underneath the ‘wood tiled shingles’ are rotting and very soon, ‘sadly’, they will be unable to hold the heavy church bells.
