Only as anecdata, many years ago, circa 2000, I was marginally involved in a project for the re-building of Stari Most (the bridge at Mostar): https://en.wikipedia.org/wiki/Stari_Most https://en.wikipedia.org/wiki/Stari_Most the initial team of "modern" structural engineers were convinced - after mathematical analysis and computers simulations - that the bridge could not possibly be re-built exactly as it was. Then we contacted to verify the calculations an "old" structural engineer that believed that if something has been built and resisted (before the bombing) some 400 years, it can be built and is resistant enough. It came out that due to some limitations of the software used at the time, and to some approximations in the design of the computer model, the resistance (and influence) of the lead fixed steel pins (that were - for the time of building - a technical marvel) was greatly underestimated, as well as the effect of the steel strips.
