Analysis

Analyzed For The First Time

In 2017, Old Structures began work on the engineering portion of the restoration of the Serbian Orthodox Cathedral of Saint Sava. The design team is headed by Don Zivkovic and Brian Connelly of Zivkovic Connelly Architects; Shaquana Lovell from OSE performed most of the structural design. The first step of any project is to figure …

Temporary Exposure and Temporary Stability

The picture above shows the sanctuary of the Serbian Orthodox Cathedral of Saint Sava last summer, when work was starting on restoration. It is nearly the same view as the painting I used for yesterday’s post. The loss of the roof and the destruction of the interior of the church in the fire explain, I …

Modeling and Understanding, Part 6 and the End For Now

Part 1, part 2, part 3, part 4, and part 5 give the context. Engineers create models. So do architects, economists, sociologists, physicists, biologists, and sculptors, among others. What makes our models special? Not every single structural engineering problem is life and death, but a large percentage of them carry the possibility of catastrophic failure if dealt with improperly. …

Modeling and Understanding, Part 5

Part 1, part 2, part 3, and part 4 give the context. Strength and stiffness are both easy to understand in a qualitative way, as how much load something can hold and how much it will move when it holds the load, but non-engineers tend to underestimate the amount of time engineers spend addressing stiffness issues. I find …

Modeling and Understanding, Part 4

Part 1, part 2, and part 3 give the context. Also, it occurs to me that my illustrations in this series have gone from an entire structure to a piece of a structure, to a drawing of a structure, to an analysis diagram. I’m sure that progression means something, but I’m not sure what. If …
